What to do if my computer is infected by a virus or a malware?
I think my PC might be infected. Whenever I try to install Kaspersky it says it can't install because the PC may be infected, and that I need to first install the Virus Removal Tool.
I've also tried to install Microsoft Security Essentials but it says I'm not able to because Windows Defender is running - I should turn it off first before continuing to install MSE. However I don't seem to be able to turn it off; my PC is running in safe mode with networking.
What should I do to start Windows normally? Is there any solution or do I need to format the C: drive? My audio device is not working and Adobe as well.
Which antivirus should I use to avoid any problems in the future - is only having an antivirus sufficient, or I should also install a firewall, virus removal tool, etc?
