I use an online backup service to backup my files and synchronize some folders between my computers (see (sugarsync.com). At start-up, this program runs through all the files, looking for changes in the files and so on. This slows my computer down for a while and I would like to speed up the process. I've noticed that Eset Antivirus seems to be scanning all the files that Sugarsync is scanning -- the CPU usage for the two processes moves up and down in parallel (as observed in Windows Task Manager.) My theory is that these files (being scanned by Sugarsync) are already safe -- they get scanned by period scans and are scanned automatically when they are opened by other programs (e.g. Microsoft Word). Therefore it is redundant to have Eset Antivirus re-scanning everything at computer startup. Is there some kind of "ignore" option where I could tell Eset to ignore Sugarsync "reads" of files on my hard disk? If so, is this a good idea? Advanced follow-up question: It might not be a bad idea for Sugarsync to scan files that Sugarsync "writes" to my hard disk. Is that still possible? (This isn't really an issue for me -- I have Eset on all my computers and therefore trust anything Sugarsync downloads from the cloud.) Thanks in advance!
