First of all, wellcome 8)

If you search the board for the word AOL you’ll find some answers…
Anyway, I think AOL could bring some troubles to avast if I’m not wrong… avast scans only pop3/smtp email accounts and AOL, if I’m correct, uses it’s own protocol :cry:

avast is only an antivirus (but the best one ;D)
You should have your firewall and any other security application that you want/need (pop up and spam blocker, script blocker, etc.).
To uninstall NAV, search a little the board or, if you want, click on FAQ in my link and browse a little. Enjoy :wink:
