Windows XP deleting PF files

[neng]

I just did a scan for virus. It detected as malware in a PF file,under C:\windows\system32. EIPKUEVVAW.EXE-028163C6.pf and i have no idea what it is.
It say clean failed. can i delete the whole file? or is there other way?

A .pf file is normally found in, windows/prefetch and should not really be in the system32 folder ... go ahead and delete it.

I'd be interested in what AV/Anti-Malware program found it.

As usual, very little information here.
