Hello everyone,

I am trying to fight off a nasty infection with unknown progress.
I turned on a friend's computer and was invaded by Antivirus Soft with messages flying everywhere, fake resident shield (AVG) alerts, Windows Security Center icons appearing constantly in the taskbar, and the inability to open any helpful exe files (The application cannot execute... blah blah blah, would you like to open your antivirus software?")

I couldn't go into safe mode either (reboots after trying to load Mup.sys)

I was able to open Firefox and search around but anytime I tried to open a helpful file (ComboFix, ProcessExplorer, Task Manager) they would open for a couple of seconds and then close.

So I then decided to reboot the computer and attempt to try and open task manager and catch the culprit before it could invade the computer, but to my great surprise, it never came up. Nothing. No trace of Antivirus Soft ANYWHERE.

The only thing I get at the moment are Resident Shield Alerts from AVG complaining about some Generic Trojan and I have clicked "Move to vault" every time.

I also just ran MalwareBytes full scan and it found 2 things which I removed.

My friend mentioned that this exact scenario happened to him already: Antivirus Soft invasion and then nothing after a reboot. Then it randomly came back, and now I had the same issue.

What is going on here?

Thank you for taking your time to read guys.

Thank you for your reply Animal, and sorry about the wrong forum post.

I have done everything on that guide as a preventative measure, but if you read my post you'll notice the strange behavior I am getting. Also, I still cannot get into safe mode, constant reboots after Mup.sys
