Sometimes, it's infected or damaged in such a way that the only solution is to go back to
- your latest image backup, if you made one
- factory conditions and go forward again
- reset Windows from within Windows
- reset Windows after booting from the install disc or stick
- do a really clean install
This might be one of those cases.
A month ago, I installed a program. I don't really remember what it was
However, It had adware. It gave me everything but what I need.
Now my browser closes whenever I type certain words like "headway" , "password" and "adware". My CPU Usage is on 100% most of the time. Antivirus "Avast" detected viruses, but it was too late. I did some scans and now my CPU Usage is on 70%. Also my Antivirus did risky things like detecting a system file as a virus. It was deleted automatically. I couldn't do nothing. After that my computer system was randomly crashing. I restored the system. The sys file is back, but virus is still here. I did very risky thing such as replacing .sys files with the same ATI files which are .sy_ . I made them .sys by expanding and instead of deleting system files which antivirus told me are infected, I reaplaced them. It had very little effect. I think its deeply hidden in my computer
Any help? Thanks!
