I was having problems with mail client Thunderbird and decided to look more closely into what is happening. I run my Thunderbird so that it stores some of the mail folders locally on separate encrypted volume on my Mac OS X. The actual INBOX folder file in my case is 850MB. The problem now occurs whenever I try to access that folder *and* have F-Secure real-time scanning on. Unfortunately even browsing the folder in Thunderbird means that F-Secure real-time scanning starts to check the 850MB file again and I suspect this may happen for each I/O operation making the Thunderbird pain to use as the UI slows down. Now this started to bug me sometime in the summer, so something probably changed with F-Secure Antivirus for Mac OS X then. My question now is that is there anything I can do to fix this except to try to reduce my mail folder size? From the F-Secure Antivirus UI I could not find a place where I can add exceptions of files, which should not be scanned. This would have been my first choice unless there's something clever just around the corner in the next version of F-Secure Antivirus for Mac OS X?
