I recently got a virus that randomly opens 18+ ads on my browser, I tried scanning with Malwarebytes, it got instantly shut down, I tried Windows Defender, the real time protection kept closing itself, I tried the eset one time online scanner it closed my browser. I think it infected the svchost.exe because looking at process explorer I can see that there are TONS of svchost processes
Have you tried a trial of Emsisoft?
Uses 2 scanners.
It got somehow better, I ran my pc in Safe Mode and was able to scan with a ESET online scanner, it removed some files, now i can access my antivirus on normal boot. But still i cant type words that contain the word "rogue" "adware" etc... neither access sites of antiviruses/scanners.
