I wouldn't really recommend any of those ones you mentioned... I've tried them all and none of them actually stopped a virus for me (maybe just for a few days here and there)... honestly, I don't think any antivirus out there can truly do it anymore, though it's probably still good to have something like Avast
ps.
new viruses pop up every single day, while antivirus software only gets updated once a year!
