Avasti seems to work well for me, and I use jetico personal firewall. Open source is a great way to go for programs, and they are slowly improving.

AVG or AVAST are both free, reliable, and good programs.
AVG from Grisoft. Excellent . . . and free.
go to super anti virus, when you down load it you can do free checks and it deletes all problems, only thing is you cant program it to do it autamatically, you have to upgrade it and pay, but if you just do a check with it twice a week, you should have no problems, i use it, and its freeeeeee, x, and its good
It depends on what OS you are running. Most Windows users prefer AVG software, free version. Don't forget to use your firewall too!
