How to Recover Deleted Files


How to Recover Deleted Files

Have you accidentally deleted your files from the Hard disk? Do you desperately want to recover them back? Well you need not panic! It is possible to recover the deleted files back from the hard disk  (even after you have Shift+Deleted)  provided you act as soon as you realize that the files are deleted and use the best deleted files recovery software. In this post you will find a detailed information on how to recover the deleted files from your Windows PC or Mac.
Today there exists hundreds of data recovery tools and softwares on the market which boast to recover 100% of all the deleted files back in the original condition. But in reality most of these softwares are neither effective nor capable of recovering your files back. So it is very much necessary to make the right choice of the file recovery software in order to recover deleted files back in the original condition. We recommend the following softwares to recover the deleted files:
Stellar Phoenix is one of the best company specializing in deleted files recovery services and solutions since 1993. Stellar’s Data Recovery Solutions encompasses a wide range of software for almost any data loss situation ranging from accidental formats to virus attacks to software malfunctions. Hence Stellar provides the best tools to recover deleted files with over 1,000,000 satisfied customers across 137 countries.

How the File Deletion Process Works?

When you delete a file from your computer (or even from the recycle bin) the file is not actually deleted. Unlike what most people think, the file is not permanantly deleted or dropped from your hard disk. Let’s take an example of a book containing 50 pages. Suppose when you delete the page 25, assume that only the entry in the index which points to the page 25 is deleted and not actually the page 25 itself. Likewise when you delete a file from your hard disk, only the pointer which points to this file is removed and not actually the file itself. This file still exists intact and is 100% possible to recover it back in the original condition. In this condition the file becomes invisible and hence appears to have deleted.

What are the Chances of Recovering my Files Back?

Since the operating system doesn’t immediately re-use the space from the deleted files, it is most certainly possible to recover the deleted files back in 100% original condition. It may take up a very long time for those files to be completely deleted since the modern hard disks have ample capacity. Hence the chances are too less that the space from the deleted files are re-used immediately. So, it is really worth to try out the file recovery softwares like Stellar Data Recovery for Windows or Stellar Data Recover for Mac. Some files are reported to have recovered even after years of it’s deletion. However for the best results, it is recommended that you use the file recovery software as immediately as possible to recover your files.

Recovering the Deleted Files

In order to recover the deleted files all you need to do is perform a scan (search) for the deleted files using a File Recovery Software. Please be informed that there is no manual way to recover the deleted files. The Phoenix Data Recovery software performs a thorough scanning of the hard disk sector by sector and will locate the existence of deleted files to restore them back in the original condition. It is the only software that supports 185 popular file types including Windows NT Registry, JPEG, MP4, GIF, BMP and MS Word files. The software offers rich graphical support and incorporates advanced scanning methods to completely scan and recover deleted files from your hard drive. With this you can

How to Test the Working of your Antivirus – EICAR Test


Have you ever wondered how to test your Antivirus software to ensure it’s proper working? Well here is a quick and easy way to test your antivirus. The process is called EICAR test which will work on any antivirus and was developed by European Institute of Computer Antivirus Research. This process can be used by people, companies and antivirus programmers to test the proper functioning of the antivirus/antimalware software without having to deal with the real computer virus which can cause damage to the computer. Here is a step-by-step procedure to test your antivirus.
1. Open a notepad (New Text Document.TXT) and copy the following code exactly onto it, and save the notepad.
EICAR Test code
X5O!P%@AP[4\PZX54(P^)7CC)7}$EICAR-STANDARD-ANTIVIRUS-TEST-FILE!$H+H*
2. Rename the file from New Text Document.TXT to myfile.com
3. Now run the antivirus scan on this myfile.com file.
If the antivirus is functioning properly on your computer, then it should generate a warning and immediately delete the file upon scanning. Otherwise you may have to re-install your antivirus.
NOTE: Most antivirus will pop-out a warning message in the Step-1 itself
You can also place the myfile.com file in a ZIP or RAR file and run a scan on it so as to ensure whether your antivirus can detect the test string in the compressed archive. Any antivirus when scanning this file will respond exactly as it will do for a genuine virus/malicious code. This test will cause no damage to your computer even though the antivirus will flag it as a malicious script. Hence it is the safest method to test the proper functioning of any antivirus.

5 Ways to Speed Up PC

Speed Up PC
Are you fed up with your slow PC? Well you can Speed Up your PC by 3 times. In this post you’ll find some of the most significant ways to speed up your PC. For your convenience, I ’ll split this post into 2 parts.
1. Automatic Ways to Speed Up PC (Using PC Speed Up Softwares)
2. Manual Ways to Speed Up PC

Automatic Ways to Speed Up PC

You can use a PC Optimizer Tool to automatically boost the Speed of your PC without the need to worry about the manual ways of doing it. These tools will automatically find and fix upto 99% of your PC errors by optimizing the Windows registry, cleaning up junk files, removing unwanted items from the start up etc. This can speed up your PC and Internet speed by upto 3 times. Here are some of the best PC Optimizer Programs that I recommend.
Using a PC Optimizer is the easiest way to speed up your PC. This is because, most of the performance tweaks such as Registry Cleanup cannot be done manually.

Manual Ways to Speed Up Your PC

1. Free Up Disk Space to increase the speed of your PC
  • Remove temporary Internet files.
  • Empty the Recycle Bin.
  • Remove Windows temporary files.
  • Uninstall Programs that you no longer use.
2. Periodically Perform Hard Disk Defragment. This can Speed Up your PC significantly.
3. Clean Up your Registry (Highly Recommended)
Cleaning Up your Windows Registry is very much necessary to speed up your PC. Unfortunately you cannot do this manually. You have to use a Registry Cleaner to do this. Here is the best registry cleaner on the web.
A complete review of registry cleaners can be found at Registry Cleaner Comparison
4. Clean Up the browser cache to Speed Up your Internet.
Spywares can really hurt the performance of your PC. So, install a good anti-spyware to protect your PC from spywares and improve the speed of your PC. I recommend the following Antispywares to protect your PC.

Which is the Best Way to Speed Up my PC? (Auto or Manual)

The best way to speed Up your PC is by using a PC Optimizer such as Perfect Optimizeror Registry Easy. This is because, manual ways can only perform 30-40% of the tweaks to improve the speed of your PC, but the most important aspect of the Speed Up process such as Registry clean Up and other advanced performance tweaks can only be done using a PC Optimizer software. So if you are serious about improving the speed of your PC, then you need to use a PC Optimizer.

Ways to Hack Orkut Account



Ways to Hack Orkut Account

1. Using Keyloggers is one of the Easiest Way to Hack Orkut password. Keylogger programs can spy on what the user types from the keyboard. If you think that you can just uninstall such programs, you are wrong as they are completely hidden.
A keylogger, sometimes called a keystroke logger, key logger, or system monitor, is a hardware device or small program that monitors each keystroke a user types on a specific computer’s keyboard. Keylogger is the easiest way to hack an Orkut account.
A keylogger program is widely available on the Internet. Some of the best ones are listed below
A detailed information on Keylogger Hack can be found in my post Hacking an Email Account.
2. Phishing Attack is the most popular way of hacking/stealing other’s password. This attact works by using fake login pages to fool innocent Orkut users to enter their Orkut username and password in these fake login pages instead of the real ones. When the users land on these page they enter their Orkut username and password thinking it to be the real page but actually it is other way round. It submits all the entered details to the creator of the fake login page. In this way it’s obvious for many people to lose their Orkut account password.
3. Orkut New Features: Some sites on internet may claim to offer many additional features for Orkut users. Also these sites will offer a login page from their own website and force users to login to their Orkut account from this page itself inorder to gain access to the additional features. In fact these sites are acam and they take away your password when you enter your Orkut username and password on their pages. This is similar to that of phishing attack.
4. Community Links: Many times you are provided with a link to a community in a scrap. Read the link carefully, It may be something like http://www.okrut.com/Community.aspx?cmm=22910233 OKRUT not ORKUT. This is definitely a trap created by the hacker to hack your Orkut password. Clicking on this link will take you to a fake login page and there you loose up your password.
5. Java script: You must have seen the circulating scraps that asks you to paste this code in your address bar and see what happens! Well sometimes they also leak out your information. Check the code and if you are unsure of what to do, then I recommend not to use it. So be careful, javascripts can even be used to hack Orkut!
6. Primary mail address: If by some means a hacker came to know the password of your Yahoo mail or Gmail, which users normally keeps as their primary mail address in their Orkut account, then hacker can hack Orkut account by simply using USER ID and clicking on ‘forget password’. This way Google will send link to the already hacked primary email ID to change the password of the Orkut account. Hence the email hacker will change your Orkut account’s password. Hence your, Orkut account is hacked too.
So a better thing would be to keep a very unknown or useless email ID of yours as primary email id so that if the hacker clicks on ‘Forgot password’ the password changing link goes to an unknown email id i.e. not known to the hacker. Hence your Orkut account saved.
So, I hope that this post not only teaches you to hack Orkut account but also to hack protect your Orkut account.

Hack Facebook Password


Hack Facebook Password

Hack Facebook PasswordWondering to know how to hack Facebook password? Well before you try to hack any Facebook password, it is necessary to understand the real ways of hacking that actually work and also those that are simply scam and don’t work. Everyday I get a lot of emails where people ask me “how to hack Facebook password?” So in this post I have taken up this topic to show you the possible ways to do that!
Today even a noob computer user (perhaps like you) can easily hack Facebook or any other social networking site with ease in a matter of hours and thus hacking is no longer the secret art of a Russian hacker! Well the idea behind this post is to expose the truth behind hacking Facebook account so that you can stay away from all those scam sites which will rip off your pockets by making false promises to obtain any password for you. Also this post is not meant to encourage people into hacking Facebook, but rather it is meant to educate the Internet users to be aware of the common scams and frauds and stay away from them.
With my experience of over 7 years in the field of ethical hacking and security, all I can tell you is that there are only two ways to successfully hack a Facebook account.

1. Keylogging – Easiest Way to Hack Facebook Password

Keylogging refers to simply recording each and every keystroke that is  typed on a specific computer’s keyboard. This is possible with the use of a small computer program called keylogger (also known as spy software). Once installed, this program will  automatically load from the start-up, runs in invisible mode and start capturing each and every keystroke that was typed on the computer.  Some keyloggers with advanced features can also capture screenshots and monitor every activity on the computer. To install and use a keylogger one doesn’t need to have any special knowledge. That means anyone with a basic knowledge of computer can install and use this software with ease. Hence for a novice computer user this method is the easiest way to hack Facebook password. I recommend the following keylogger as the best for gaining access to facebook password.

How to Detect Anonymous IP Addresses


How to Detect Anonymous IP Addresses


Detect-ProxyAs the fraudsters are now becoming more sophisticated in bypassing the Geo-location controls by using proxies (Anonymous IPs) to spoof their IP address, it has become very much necessary to come up with a means for detecting the proxies so that the authenticity of the users can be verified. Using a proxy (web proxy) is the simplest and easiest way to conceal the IP address of an Internet user and maintain the online privacy. However proxies are more widely used by online fraudsters to engage in cyber crimes since it is the easiest way to hide their actual Geo-location such as city/country through a spoofed IP address. Following are some of the examples where fraudsters use the proxies to hide their actual IP.
1. Credit Card Frauds
For example, say a Nigerian fraudster tries to purchase goods online with a stolen credit card for which the billing address is associated with New York. Most credit card merchants use Geo-location to block orders from countries like Nigeria and other high risk countries. So in order to bypass this restriction the credit card fraudster uses a proxy to spoof his IP address so that it appears to have come from New York. The IP address location appears to be legitimate since it is in the same city as the billing address. A proxy check would be needed to flag this order.
2. Bypass Website Country Restrictions
Some website services are restricted to users form only a selected list of countries. For example, a paid survey may be restricted only to countries like United States and Canada. So a user from say China may use a proxy so as to make his IP appear to have come from U.S. so that he can earn from participating in the paid survey.

Proxy Detection Services

So in order to stop such online frauds, Proxy Detection has become a critical component. Today most companies, credit card merchants and websites that deal with e-commerce transactions make use of Proxy Detection Services like MaxMind andFraudLabs to detect the usage of proxy or spoofed IP from users participating online.
Proxy Detection web services allow instant detection of anonymous IP addresses. Even though the use of proxy address by users is not a direct indication of fraudulent behaviour, it can often indicate the intention of the user to hide his or her real IP. In fact, some of the most used ISPs like AOL and MSN are forms of proxies and are used by both good and bad consumers.
How Proxy Detection Works?
Proxy detection services often rely on IP addresses to determine whether or not the IP is a proxy. Merchants can obtain the IP address of the users from the HTTP header on the order that comes into their website. This IP address is sent to the proxy detecting service in real time to confirm it’s authenticity.
The proxy detection services on the other hand compare this IP against a known list of flagged IPs that belong to proxy services. If the IP is not on the list then it is authenticated and the confirmation is sent back to the merchant. Otherwise it is reported to be a suspected proxy. These proxy detection services work continuously to grab a list or range of IPs that are commonly used for proxy services. With this it is possible to tell whether or not a given IP address is a proxy or spoofed IP.
How to Tell Whether a given IP is Real or a Proxy?
There are a few free sites that help you determine whether or not a given IP is a proxy. You can use free services like WhatisMyIPAddress to detect proxy IPs. Just enter the suspected IP in the field and click on “Lookup IP Address” button to check the IP address. If it is a suspected proxy then you will see the results something as follows.
Detect Anonymous Proxy
So for all those who think that they can escape by using a spoofed IP, this post is the answer. I hope this information helps. Pass your comments.

How Antivirus Software Works


How Antivirus Works

An antivirus software typically uses a variety of strategies in detecting and removing viruses, worms and other malware programs. The following are the two most widely employed identification methods:

1. Signature-based dectection (Dictionary approach)

This is the most commonly employed method which involves searching for known patterns of virus within a given file. Every antivirus software will have a dictionary of sample malware codes called signatures in it’s database. Whenever a file is examined, the antivirus refers to the dictionary of sample codes present within it’s database and compares the same with the current file. If the piece of code within the file matches with the one in it’s dictionary then it is flagged and proper action is taken immediately so as to stop the virus from further replicating. The antivirus may choose to repair the file, quarantine or delete it permanently based on it’s potential risk. 
As new viruses and malwares are created and released every day, this method of detection cannot defend against new malwares unless their samples are collected and signatures are released by the antivirus software company. Some companies may also encourage the users to upload new viruses or variants, so that the virus can be analyzed and the signature can be added to the dictionary.
Signature based detection can be very effective, but requires frequent updates of the virus signature dictionary. Hence the users must update their antivirus software on a regular basis so as to defend against new threats that are released daily.

2. Heuristic-based detection (Suspicious behaviour approach)

Heuristic-based detection involves identifying suspicious behaviour from any given program which might indicate a potential risk. This approach is used by some of the sophisticated antivirus softwares to identify new malware and variants of known malware. Unlike the signature based approach, here the antivirus doesn’t attempt to identify known viruses, but instead monitors the behavior of all programs.
For example, malicious behaviours like a program trying to write data to an executable program is flagged and the user is alerted about this action. This method of detection gives an additional level of security from unidentified threats.
File emulation: This is another type of heuristic-based approach where a given program is executed in a virtual environment and the actions performed by it are logged. Based on the actions logged, the antivirus software can determine if the program is malicious or not and carry out necessary actions in order to clean the infection.
Most commercial antivirus softwares use a combination of both signature-based and heuristic-based approaches to combat malware.

Issues of concern

Zero-day threats: A zero-day (zero-hour ) threat or attack is where a malware tries to exploit computer application vulnerabilities that are yet unidentified by the antivirus software companies. These attacks are used to cause damage to the computer even before they are identified. Since patches are not yet released for these kind of new threats, they can easily manage to bypass the antivirus software and carry out malicious actions. However most of the threats are identified after a day or two of it’s release, but damage caused by them before identification is quite inevitable.
Daily Updates: Since new viruses and threats are released everyday, it is most essential to update the antivirus software so as to keep the virus definitions up-to-date. Most softwares will have an auto-update feature so that the virus definitions are updated whenever the computer is connected to the Internet.
Effectiveness: Even though an antivirus software can catch almost every malware, it is still not 100% foolproof against all kinds of threats. As explained earlier, a zero-day threat can easily bypass the protective shield of the antivirus software. Also virus authors have tried to stay a step ahead by writing “oligomorphic“, “polymorphic” and, more recently, “metamorphic” virus codes, which will encrypt parts of themselves or otherwise modify themselves as a method of disguise, so as to not match virus signatures in the dictionary.
Thus user education is as important as antivirus software; users must be trained to practice safe surfing habits such as downloading files only from trusted websites and not blindly executing a program that is unknown or obtained from an untrusted source. I hope this article will help you understand the working of an antivirus software.
