yeah. Cause i think its always the same spammer, i found some information, how to know that this is a virus:
1. There is always a file called ,,mod files" Open it with Wordpad. If it conatins only senseless asdfoiasdf etc. dont open the jar.
2. He uses even for Textre Pack "Installers". Dont use them! Every jar, which is called INSTALLER is probably a virus.
I´ll report you , if i find virus topics in pmc.
Have a nice day,
