For reference, I installed this trial version of their antivirus program while removing a virus from a friend's PC. Next thing I know, I started getting error messages in my email programs. I use Outlook, Outlook Express, Mail Washer, & Thunderbird. NONE of them would work. It wouldn't connect to the mail server on port 110. I have two other anti-virus programs running in addition. My emails worked fined before I installed NOD32. I went into NOD32 control panel and disabled the incoming email virus scan. My emails started working fine again. I wouldn't recommend this product as an antivirus program because of this.
