My computer's been lagging like crazy lately.

I ran Malwarebytes a couple times on my extra directory, but it always ends up with an error in a place like this:D:\_C_Backup\Drivers\Video\UpdatedDriver_3-11-2004\setupdir

Is the setupdir infected? Sorry 'bout this being a really vague question. If you can't figure it out, I understand. Just wanted some pointers.

Hello.
A backup folder? other than MBAM getting stuck, any other problems?
