Hello, After several minutes or scanning, Malwarebytes goes non-responsive. When it stops responding, the screen is similar to this Objects Scanned: 30648 Objects Infected: 2 Time Elapsed: 3 minute(s), 5 second(s) Currently Scanning: c:\Windows\system32\Config\SECURITY.LOG1 It usually stops on SECURITY.LOG1, but not always. I am pretty sure that my laptop is infected because I had to rename the executable just to get it to run. I followed the procedure below that I found on this forum because I thought my Norton Anti-virus was preventing it from running. Still will not run. I also cannot install HijackThis because as soon as I try to install, I get a BSOD. OS=Windows Vista Home premium Thinkpad T61. Any guidance is appreciated.
