I have what I assume to be a virus on my computer. It started out as just a minor nuisance, as all it would do was redirect my internet browser when clicking a link from Google. I ran Malwarebytes. It said it found a trojan, which it then removed. Now I have a svchost.exe process that is taking up close to 100% of my CPU usage. Every program I've tried to run (HijackThis, Malwarebytes, SuperAntiSpyware, ProcessExplorer, AVG, etc.) will start to run, then close on thier own. When trying to reopen I get a message saying the the installer does not have sufficient privileges... I can also hear the "pop-up" message sound although there is nothing that has opened or closed. The last virus I had on this computer that created pop-ups "in the background" was installed in the BIOS. After updating the BIOS the virus was gone. I tried updating the BIOS this time and it will not complete.
