Currently using CA internet Security for virus, spyware, and firewall protection.
I keep getting a notice that I have a Virut virus, I have tried Symantecs Virut Removal Tool but it keeps coming back.
Any ideas on this would be appreciated

Hello.

Virut infections are very nasty. Best option is to Format now. Take a read below.

Posted ImageVirut File Infector Warning

Your system is infected with a polymorphic file infector called Virut. Virut is capable of infecting all the machine's executable files (.exe) and screensaver files (.scr) and also web pages (.html and .htm). However, the problem is that the virus has a number of bugs in its code, and as a result, it may misinfect a proportion of executable files and therefore, the files are corrupted beyond repair. As of now, security experts suggest that a clean Reinstall or Reformat is the only way to clean the infection and it is the only way to return the machine to its normal working state.

Backup all your documents and important items (personal data, work documents, etc) only. DO NOT backup any executable files (softwares) and screensavers (*.scr) or any web pages (*.html or *.htm). It attempts to infect any accessed .exe or .scr or .html/.htm files by appending itself to the executable.

Also, try to avoid backing up compressed files (zip/cab/rar) files that have .exe or .scr files inside them. Virut can penetrate and infect .exe files inside compressed files too.

More information on Virut can be found over here and here

Tell me what you decide to do.

With Regards,
Extremeboy

Newer variants can even get by your AV protection

Your System is infected with Virut!!
Virut is a file infecting virus which is able to modify itself each and every time it runs. In addition, when it infects, sometimes it will destroy the file it tries to latch onto.
For these reasons, you really can't truly fix Virut. You will need to format/reinstall the operating system on this machine.

There are bugs in the viral code. When the virus produces infected files, it also creates non-functional files that also contain the virus.

W32/Virut.h is a polymorphic, entry point obscuring (EPO) file infector with IRC bot functionality. It can accept commands to download other malware on the compromised machine.
It appends to the end of the last section of executable (PE) files an encrypted copy of its code. The decryptor is polymorphic and can be located either:
Immediately before the encrypted code at the end of the last section
At the end of the code section of the infected host in 'slack-space' (assuming there is any)
At the original entry point of the host (overwriting the original host code)

No. Try not. Do... or do not. There is no try.
