I was looking for a document on my c drive when I found this folder "SB_usb_log". I don't know what its for and I suspect anything I don't recognize. It's a read only file. I have Zone Alarm, Up to date Norton anti virus, Adaware and CC Cleaner. I also used a register cleaner about 3 mos ago. I checked all my installed programs and they are programs I installed. Nothing weird or new. I don't get redirected on my IE and I dont have pop ups. What I do have is a really slow puter. Dell Dimension, 8200 Intel pent 4, 2.40 ghz and 512 RAM, XP OS. Its always been really quick, booted fast no prob. Now it takes upwards of 5/6 minutes for me to boot up. Ive scanned, defragged etc. nothing. Is this my puter or am I infested and how did that happen?
