|I've done some searching at this site but not found this exact problem addressed. I believe it may be virus related because the other night, after downloading and running a recommended temp file cleaner called “ccleaner,” I received a warning from my AV that a trojan horse was detected. I moved it to "the chest" as the program advised. The next day I booted my PC and it seemed to load normally but any application I ran froze after about 5 minutes and it now does so every time I reboot. When I try safe mode, I only get screen full of white code lines on black background. I attempted to run my virus program and it starts a routine memory check but stops each time after about a minute at the same file - sshnas21.dll - and freezes there. No other programs will run, including Windows Task Manager.|
Any suggestions would be appreciated.
