I have excluded my Steam folders, in this case M:\SteamLibrary

But BitDefender blocks the Call of Duty Black Ops II Zombies EXE file still!

The Events window is useless because although it gives you the choice to either restore or delete the file if you click on restore then a second later the anti-virus just deletes it again. Why doesn't it exclude automatically the files you have restored? Obviously you have restored them because you wish for them to remain on your computer and not be automatically deleted 3 seconds later!!
This Anti-Virus program also annoys me because from what I can tell there is no way to make it prompt when it finds a virus, it just instantly deletes it which is very inconvenient when you want to exclude it.
Another complain is that if you go to the quarantine window in the Anti-Virus module it's always empty, you actually have to click a tiny icon at the top of the program and then click Events to actually see what viruses have been detected, not sure who made the design decisions on this but it made it very difficult to restore important files when they are falsely detected. Have the designers tried to actually use this program?
I like that this program is so light on resources and it has a reasonably nice UI and some cool features but I don't think i'll be renewing it at the end of my trial as simple things like making exclusions, choosing what action to take when a virus is detected and having the ability to right click on the tray icon and temporarily disable the anti-virus for a period of time are sorely missing. This might be excusable for an anti-virus software that is new to market but it's obvious you have done zero research into your competition. Get with the game BitDefender, lots of free anti-virus programs already have these features and more.
