heello
guys my pc got infected by troyans about 2 days ago and i analize it and found a troyan virus in the exsro folder (silkroad.exe)
i got infected by the game or for other thin?:o:o

ehmm
you probably dowloaded from a link that you never scaned

the the website then it wasnt your Silkroad folder
also
if it was from the website, then it might have been the media.pk2

but its not harmfull
