Linux AV problem or windows AV problem??

[thilina]

Guys,i have both win xp & ubuntu.Somedays ago i installed Aegis Virus scanner in ubuntu.When I scanned my Windows partition(NTFS) with it
it says my pc is infected with "W32/Magistr.a@MM" virus!.But the suprise is that any of my windows AV scanners didnt detect any virus in my system!!!.I have installed AVG Free edition,Clam AV,Bit diffender in my windows section.None of these detects a virus.

So my problem is that is linux AV scanner wrong??
Or is my pc really infected??

Plz give me some quick replies guys.I cant stay in the net for a long time.

Forgot to tell you guys,Another virus is indicated.Its "W32/Netsky.c@MM".But only a one file is infected with this one.

just locate the file yaar.also AV's sometime will fail in compressed archives(eg;zip,rar,etc)then try scanning online or update ur av's.
