I recently received a security alert via my ISP warning of a possible virus attack.
I was advised to run a different virus software to see if I had an infection. I ran SUPERAntispyware, as recommended, and it found the virus Trojan.Agent/Gen-Nullo[Short]
How did this virus get past Avast 4 Professional?
I run daily updates and regular scans - Do I need to do something in my configuration settings?
