I ran kapersky scan and it found nothing .
To be double safe i then ran trendmicro Housecall.
It comes back and says it found a dangerous rootkit called klavemu1257~ and it wants to remove it.

I know kapersky has a dll that starts with that name.
Is this rootkit part of kapersky or should i let trendmicro remove it?

hello
does it say in which folder it found it?

it says this:

klavemu1257~ HIDDEN FILE Rootkit

E:\Documents and Settings\All Users\Application Data\Kapersky Lab\AVP8\Bases\klavemu1257400090.kdl

that's kaspersky's file, it's a fp on trend's part
