Total Security & Windows Police Pro

My home computer has been infected with the Total Security virus.  I have Norton AntiVirus 2009 which didn't catch it and now won't run.

 

I've read the forums here & on other sites and have tried a few different things:

 

  • I can bring Task Manager up right after login and end the process for 1229374.exe. This stops the Windows Police pop-ups, but there are still some balloon warnings about needing to protect my computer.
  • I can't run Norton, MalwareBytes, or AVG. They're all installed on the computer but won't run.
  • When I try to start in safe mode, it bluescreens. 
  • I can't connect to the internet.

 

I've manually deleted a Windows Police Pro folder, the 1229374 folder, and some other related files.

 

I'm not even sure how the virus arrived on my computer... I didn't open any email attachments or visit any unusual sites... It'd be nice to know what to watch out for so I don't do it again!

 

Any suggestions?  If I have to do a factory reset/restore, will that virus still be lurking in the system?

 

Thanks in advance for any help!
