I installed BitDefender Internet Security 2009 and found the system to be extremely slow compared with IS 2008. Was wondering if it's due to enabling "scan accessed files" under "Real-time protection". If so should I uncheck scan accessed files? Will my system be unprotected if I unchecked it? In the 2008 version, I only enabled scanning when writing but not reading but I can't find this option in 2009. Is scan accessed files sames as scan when reading? If so I think that's the problem causing the slow-down. Also if I unchecked it the monitor would recognize that as a problem which requires fixing. Is it safe to turn off monitoring for real-time protection? Any comments would be greatly appreciated. If I can't fix this I might go back to 2008 instead cos it's simply too sluggish for my daily work.
