I have installed clamAv 0.85 for windows many times and have always the same problem. After 2 or 3 days clamav stop to run. In the system all is apparently ok. ( no error in mailenable, plesk, system, clam log file, ecc... The problem is that plesk don't call clamav for check virus for incoming mail. What i Do for this? When i notice clamAv don't work, uninstall clamav, reboot my system, install clamav and all work fine.... for other 3 days.(( (when clamav don't work for incoming mail i try to scan manualy and it go well.) I have plesk 7.5.2 on windows 2003. Tks for all indication!
