Virus - Assistance needed - Turning PC on, pops cmd command system 32

[Anastasios]

Hi, Linus community,

 

Two days ago a got a virus on my pc. At the time it was working fine, but when I restarted it, there was a black screen with a pop-up window of cmd command mentioning "C:\windows\system32>". Since then, I don't have access to windows nor can I access bios to boot from USB in order to format windows.

 

What can I do to fix this issue?

Can I recover windows or do I need to format it? If its the later, how do I access bios?

Any suggestions?

It is very unlikely, but possible your motherboard got "infected" by a virus. So first, I would say test all your hardware, try to see if any of that failed. If not, here's what I'd do:

Remove the infected drive for now.
Clear CMOS (Remove battery, wait 10 or so mins, but it back in) from your motherboard (do this with the power supply off)

If your board can have it's BIOS flashed over USB (some asus boards support this), try that

Thank you for your reply tarfeef101.

I manage to recover the pc through task manager startup files tab, opening file location and then entering the control panel and recover to a previous date before the incident. 

 

Quite an unsual way to do so, but it worked and avoided the format!

all systems are working fine!
