Yeah not sure if this is the place i would post for Viruses and stuff but here goes. OS Vista Home Premium
It all started as i was downloading from a respectable website and when the file was almost done, one of my programs (borgchat) had numerous error messages (believe it was Fatal Error or something) so i turned off my computer to see if it would help. When i turned it back on all my startup programs started to have the "Program not responding" message INCLUDING my Antivirus, in which i could no longer run any programs for the same message would appear. so i restart it again and an error message appeared about some .dll or .ddl file (sorry didnt get name only extension) so now whenever i start windows normally i get some error about a error in the Kerrnel i believe (which was in blue screen if anyone reconizes it) so my computer crashed and i can only run in safe mode!!
So please if anyone has any clue wwhats going on or if something already happened and was posted on here please help me, i'd like to run my games such as my demos from Steam. I also forgot to mention i deleted the file that i downloaded any anything accosiated with it (ie Temp Download in Opera folder) Again please help.

Don't know how or why Arcanum.exe is infected for ive been using that games for a couple of weeks without any adverse effect and so hasnt my brother, the only thing significant wrong with Arcanum is being slow during LAN play but then again my compute is old being an Acer Aspire 5100.
