Hello,

I have read some URL redirect entries here and tried to clean my system the same way. At times things seem to be clean for a minute and then all of a sudden Windows defender finds things which claims to have been cleaned. I would appreciate your help in giving me directions for cleaning my system. Please let me know if you need more information.
I have run Malwarebyte, spybot, ccleaner, superantispyware, and ESET online cleaning. I have included logs from Malwarebyte, ESET,and hijackthis .

I was hoping someone in here could guide me through this but had to take the road on my own. To make a long story short, I believe atapi.sys was the culprit. Kaspersky detected the problem but kept causing BSOD. I ran the tool in safe mode and right after it removed the offending virus, it caused my system to go blue screen (in safe mode). Then I tried windows recovery which claimed was not able to recover but after I rebooted, it turned out that it had removed Kaspersky and everything seems to be running fine now. I read a few things about Kasperky having problems with Windows 7 but not everyone is affected the same way. Well, it did have a problem on my machine but it actually also fixed the main problem too. I thought this might help somebody.
