Hi Kenny, I already started with GMER and got the result that tzjia.sys was encountered. After this I ran Combofix which actually quarantined the reg values and the file itself. After this I deleted the tzjia.sys file. I ran comfix again after reboot to see if anything was found. Afterwards I ran another rootkit detector, avenger2, and it came up clean. So right now everything is clean. Also ran cccleaner, atfcleaner, auslogics registry cleaner to make sure everthing was running ok. Afterwards I ran malwarebytes one more time with a full system scan and it came up clean. No more blue screens untill now. That is a couple of hours running multiple programs. Let keep my fingers crossed, I really do not want to do a reinstall right now . Chrz
