When I ran a full SAS scan this morning (the free version), it picked up a trojan.agent/gen_decay. It was placed in quarintine, and I restarted the computer. But when I ran the scan again (just to be sure it was removed), it picked up the same trojan again. If it helps, the second scan seemed to detect the trojan in the very same area as a tracking cookie. (I didn't pay attention to it the first time because I was too worried.)
Should I run scans from all other program ( Avast, Malwarebytes, etc...)?
Also, should I wait until I know what's going on before logging onto anything important?
