Having problems lately with incoming email message which have large email attachments i.e. 650k+. Both Eudora and Thunderbird 188.8.131.52 have problems with large email attachments. The downloading of the message from pop3 server simply timesout. When I do the mail check via Eudora on another Win XP Pro SP3 but that has NOD32 v 2.7 installed on it the email comes down ok. Problem computer is Win XP Pro SP3 fully patched with MS critical updates and NOD 32 v 3: Virus signature database: 3541 (20081021) Update module: 1024 (20080514) Antivirus and antispyware scanner module: 1155 (20081016) Advanced heuristics module: 1078 (20081016) Archive support module: 1083 (20081016) Cleaner module: 1032 (20080724) Anti-Stealth support module: 1002 (20080723) Default settings and I made sure by resetting all the settings back to default via the Advanced setup tree option.
