Hi, I am new to here, sorry for my poor English. I have met some issues.
First is that my on-access scanning is always changed during the sys scan.
The next is that I rebooted my pc for the windows update during the sys scan, scanning for my lage achive files, then I found my disk c had missed for a lage space, nearly the same as each seize of my archive files. I don't know if this case was caused by temporary files, I hadn't setup any programs since I setup Bitdefender Win8 security.
Thanks for any help you can give me.
