I just finished cleaning this off my computer. Here's how I did it.
Because I couldn't access the internet or task manager, I created a guest account and switched users to the guest account. From there I could get on the internet and I downloaded Dr.Web CureIt and Revo Uninstaller. I moved them onto a usb drive(which may have been unnecessary but I didn't want to waste time finding out) and switched users back to the infected one. I ran the Enhanced Protection Mode in Dr Web which found 2 viruses. I then installed Revo and used Hunter Mode. Just drag the cross hairs over the splash screen of the " microsoft security essentials alert" and select the Kill and Delete process option.
You can try and kill the splash screen first with Revo, which may make it easier to use antivirus programs.

Contracting this little nasty from a web search result, it infiltrated my system via my web brower's (MSIE v7) vulnerabilities and executed. I immediately tried taskmgr.exe and regedit.exe after seeing the red/white nastygram window telling me I have a Trojan. Both .exe's popped the little window up on my screen instead of doing their thing.

So I rebooted in Safe Mode, found nothing embedded in services.exe, startup or msconfig, so I ran AutoRuns.exe (free from M$). I found some garbage, but files were not found on the system, so no help there.

I ran a free version of Avast! and my computer rebooted and scanned every file, eventually stating nothing had been found. So I let it continue to boot.

This time in Normal boot mode, I could run taskmgr.exe and regedit, so to be safe, I went to System Restore and went back a day to yesterday's checkpoint.

I have since examined taskmgr, services, startup and autoruns and found no trace of the little booger.

Oh, almost forgot, without running MSIE again, I went into Control Panels to check my Internet Options to look in Programs >> Manage Add-Ons. I only leave those from M$, Adobe, Sun and the ones I know and depend upon to be Enabled. Disable everything else (you can reenable later if needed).

I think I'm clean, but time will tell.

A Zero Cost Solution!!

Just got the alert today and I'm having the same problem. It zaps the task manager from working and the internet! Let me know if you've found a cure. Good luck.

I just fixed a friend's computer which had been running AVG Free and Windows Defender. Both are good utilities but they don't quite catch absolutely everything. On my pc I run AVG Free and Windows Defender and have had no malware or virus problems. My pc is a 10 year old Dell Dimension 8200 that still runs well with 756MB of ram. Anyway, on my friend's pc, which would not allow IE to run, I booted into safe mode with networking, was able to access the internet, downloaded malwarebytes (free version) and cleaned three things; fakems, fakealert, and hijak.exe. His pc is back to normal now.
