Yo, I just got Avast pro, and I wanted to know what you all recomend for my secound scanner.
Do you mean, non-resident? Just for on-demmand scannings? I just tested free ones, not others.
1. BitDefender (free) is easy to be at a second scanner.
2. ClamWin (without the email plugin) works too.
3. AVG antivirus (free) works but you must take care (not installing plugins and guard). Email scanning will conflict with avast if installed.
4. Antivir (free) requires manual changes to be in the same computer as avast.
5. F-Prot for DOS.
Anyway, take care and know what you're doing or you'll have conflicts in your computer
