A couple of weeks back my AVG Anti-Spyware found and quarantined a Trojan called KillAV.It was found in the following file.

C:\I386\MMSSETUP.CAB/msmsgsin.exe -> Trojan.KillAV : Cleaned with backup (quarantined)

At the time I did a Google search on it and found out that it destroyed audio/video on ones PC. I thought therefore that as it was a Trojan it was pointless leaving it in Quarantine and so I deleted it.

This morning I came across a post on this Trojan in the HiJack This forum and found out that it is in fact a false positive and I should in fact have restored it.

My question is: Is there an easy way to restore the file. Until now I haven't noticed anything out of the ordinary with the way my PC runs other than twice in the last couple of weeks when switching my monitor on I found that I had lost the flashing Icon in my sign in screen and couldn't sign in without first rebooting my PC. At that time I used to switch my monitor off at night but since I stopped switching it off and just left it on screensaver it hasn't happened again.

Thanks for any advice offered.

The easiest way would be to repair the install of Messenger by either re-installing it or first removing it and than re-installing it.

You still should have the msmsgs.exe file that's located in the C:\Program Files\Messenger folder. The file which you deleted was found and removed from the I386 folder which holds the files used to install, repair, modify, update and rebuild Windows. The critical files in that folder are also located on your Windows XP installation CD if you have one.

When a program quarantines a file or moves it into a virus vault, that file is safely held there until you take action to delete it. The reason for doing this is to prevent deletion of an essential file that may have been flagged as a "false positive". If that is the case, then you can restore the file. Doing this also allows you to view and investigate the files while keeping them from harming your computer. Thus, quarantine is just an added safety measure unless, as you have just learned, you delete them too quickly.
