It's a scare-ware rogue anti-virus. Mutated from MS Antivirus a long time ago, and has changed names as fast as people change underwear.http://en.wikipedia.org/wiki/MS_Antivirus
It will not let you perform any administrative tasks.
No access to Control Panel, so no access to,
1) Add/Remove Programs
2) Performance and Maintenance
3) Administrative Tasks
4) Task Manger
5) Windows Explorer
Just to name a few.
Soon you'll lose access to the Internet.
Suggest you use the free version of Malwarebytes Anti-Malware, and kick it to the curb.
Just because it's free don't underestimate it.
Information on Malwarebytes,http://en.wikipedia.org/wiki/Malwarebytes
Free version of Malwarebytes on Cnet,http://download.cnet.com/Malwarebytes-Anti-Malware/3000-8022_4-10804572.html
If you cannot directly download Malwarebytes to the infected computer, download to an uninfected computer, burn it to CD disk, then install it in the infected computer.
Once installed run Malwarebytes.
The time it takes to complete depends on two things.
One, if you click on Quick Scan or Full Scan
Two, how large your harddrive is, and how full it is.
Average time is around 38 to 42 minutes.
Once Malwarebytes has run, close it.
Now go to Control Panel, Performance and Maintenance, and System Restore.
(Upper left side of the window)
Once System Restore has opened, TURN IT OFF.
System Restore not only keeps what you do want, it also keeps what you Do Not want.
Yes, that scareware rogue anti-virus.
In the System Restore window go to the left side, and click on System Restore Settings.
Click in the empty square box to the left of > Turn off system restore on all drives.
Go below to the right, and click on Apply.
Now go to the left, and click on OK.
Run Malwarebytes one more time.
After Malwarebytes has finished go back to System Restore. Turn it back on.
(Click in the square again, and remove the checkmark. Then click on Apply, and then OK)
Go into system restore and create a restore point.
This way you'll have a restore point to go back to in case of trouble.
