My girlfriend's laptop, running Windows 7 x64, acquired the Windows 7 Home Security virus. I was able to get rid of it using several tutorials around this site but I am still left with several problems.
Most important is that Windows will not start up. When starting widows it will get to the Windows logo screen and when finished loading it will restart instead of actually loading Windows. I have tried starting is safe mode but it gets hung up on C windows system32 drivers classpnp.sys. The only way to get Windows to load is to enter repair mode and load a previous back-up point. I have tried replacing classpnp.sys but I am greeted with an error saying I do not have sufficient access.
I have also found out that the firewall is off and cannot be turned on, and that there is a virus in C windows assembly temp u that is simply labeled "@". When I attempt to delete it I get an error message saying it is running in Application Experience. When I temporarily disable Application Experience, I am given another error saying "@" is running in another task, which I do not remember the name of but that I cannot disable.
When I run MSE it finds about 7 virus each time and deletes them. It then suggest I restart my computer which I do. The computer then fails to restart, I repair it to an old back-up point and start all over again.
Can you please assist me?
