accidentally deleted system.sav file

i was running Anti-viral Toolkit Pro and a trojan was found in C:\SYSTEM.SAV\DELTREE.PIF -- that file came up as infected and it prompted me for an action to take and i accidentall deleted it instead of cleaning it ----- what should i do -- is this an impportant file and how do i replace it? -- and is it one of those files that i might have a hard time replacing because its content depends on the applictions that ive installed in the past? ---

Deltree is a DOS command for deleting directories with files. The PIF file is for Windows to allow it to run it. It isn't important. Neither is Deltree.You can delete directories using Explorer anyway.

If I remember correctly. System.sav is a directory containing info about a previous windows setup. It sounds to me like you have installed over an earlier version. Don't worry about it. I am not sure though how it could have become infected but if your machine is clean now then don't lose any sleep over it.

I have never come across it myself. I wouldn't worry about it though.
