My software: Thunderbird (version 126.96.36.199) NOD32 (newest version: v.4, only AV) OS: Windows XP SP3 When I receive mails (pop3), sometimes occurs a strange behavior. For example, I get 3 mails, one of them is junk and I can see it in junk folder (though subject and body are blank). The other ones not appears in any folder though my Inbox folder says "2 new mails", but my Inbox folder is empty! I do "mark folder read" every time. It's annoying. PD: I can read mails correctly. I think it's a NOD32 bug with spam/junk mails. Not this issue with nod32 v3. Sorry for my poor english. Thank you.
