How to remove hijack virus?

You may have read news about planes being hijacked. For example a passenger plane which is supposed to go to London may be hijacked by terrorists and flown to Turkey. The hijack virus does just that. If you key in a website address in your browser’s address bar and press ‘Enter’ then instead of going to that website the browser may open some other website such as an adult website or an advertisement website or a search engine website. If this happens in your computer then your browser has been infected by a hijack virus.
Why does this happen, you may wonder? This means a hijack virus has entered your computer without your knowledge and is working at its will. You can remove hijack virus and prevent it from happening using some software.
Process Guard is one such software. Just search for this software athttp://www.download.com/ and install it in your computer. This program will guard your computer against these hijack viruses

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.

          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.
