Submitted to virus lab a couple of days a go - Win32:Malware-gen

I can’t find much info on the www. http://www.google.nl/search?hl=nl&lr=&q="APISlice.dll&btnG=Zoeken&aq=f&aqi=g1&aql=&oq=&gs_rfai=

Except one post that I find interesting about Acer eDataSecurity Management and Windows Live\Messenger
