This petfilter is infected with cospick.dll, I'll edit this post to explain further.
Open this

This is just the same pet filter as the last one but this one is probably the further advanced scam try :P.
I might be wrong as well, but personally I won't open this unless somebody trusted approves that it's working, or a mod in particular which would be good.
