Spyware Terminator with Real Time Shield enabled! And Avast anti-virus.
I got infected last week. AVG did not detect it. Think it came imbedded in an image file in an email.
Downloaded Prevxx and it found it, ended up totally scrubbing the machine and reinstalling everything.
Can’t remember the virus name but it was nasty. NETSTAT showed I was hijacked by about 20-30 other computers.
Bassturds!!
So far all I have to use is OS X.
