Question

Computer Strongly Infected

Apr 26, 2018 4:51AM PDT

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!

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
or
- 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.

Avast

On this machine using avast I set my real time scanners to scan for pups.

I do not allow avast to auto do anything if it finds a bum file.

I set it to ask me.

Avast has a boot time scan which might be worth a shot.

Once malware gets in it can change many settings so removing the source does not reset these settings.

This is one of the reasons why you never run one of these machines without regular backups.
