Internet Security 2012 virus attacked my Toshiba laptop. How do I remove it?

[Brian]

Sounds like a bad virus. You need to be pretty advanced at computers to remove the virus, I removed one recently but to be honest your better off backing up your files(documents, photos, music etc) to a hard drive, reinstalling the PC, performing a full scan on your backed up files and then coping them back onto your PC.

Otherwise to clean the virus without reinstalling O/S try
1. Download these programs tdsskiller, rkill.com, mbam-setup-1.51.2.1300.exe or the latest versions.
2. Boot to safe mode and turn off system restore (on your PC)
3. Run these programs and remove anything they find
4. Download and install microsoft security essentials or AVG or any other anti-virus and perform a full scan

Hope this helps but if not reinstall O/S
