HiJackThis.exe

I just had a strange thing happin My virus detction just now found a Virus W32/Generic.Worm!p2p In the Hi Jack this file and it deleted the virus as well as HiJackthis. I have had HiJackThis on here for some time with no problum. I have done all kinds of scans From my Mcafee to Etrust House call and all came up clean. I have all kinds of stuff on here to protect aginst this kinda thing. I noticed that while looking up the worm it said it is spreed by File sharing such as Kazza and such of wich none of them i us. Any Idea why HiJack this was infected with it ?

 

Ok new problums now. It wont let me down load HiJackThis now. When i down load the Hijackthis.exe version it says w32/generic.worm!p2p was found in c:\Documents and settings\Owner\ local settings\Temporary and stops down load and when i do the zip version it says That Hijack had the worm and stops downloading.

 

I just found out my own problum. I was down loading Mcafee from a CD That was not up to date and had a old Virus Defnitions and the old defs pick HiJack this up as the worm above. Fixed with the new deftions.
