Option 1: the most drastic but guaranteed to work. Perform a clean install of the operating system. Everything will be gone, along with the virus. However, this requires a lot of backing up of data and patience.

Option 2: Download quality free anti-virus/spyware/adware programs. I recommend AVG Free, Spybot Search and Destroy, Malwarebytes Anti-Malware, Ad-Aware, and if you are using Windows Vista then might as well throw in Windows Defender (built in to Vista). I have listed so many options because some might only get some of the infections while leaving others behind. This route is not guaranteed to remove everything but is recommended.

do you have mcafee site advisor:

or a trojan remover:

i think yuo should look in a directory book to find a person who deals with this kind of stuff, they charge around £50 to have a look and whatever else to fix the problem, a bit expensive but proves successful, and then just download some other stuff with mcafee internet secrity.
or contact this person:

if you email, just say computer question, virus help, and send a link
you can buy windows recovery disks, it will format your computer, ut will get rid if ALL your documents though, unless you have a connection wire to transfer it to another compter, or do you have an external hard-drive to save it on? then format your lap top, and it works, the external hard-drives are about £60.00 and the disks i dont really know, sorry

Next, lmfao. DO NOT GO TO ANY SITES THAT HAVE MALWARE,ADWARE,OR ANYTHING ELSE (INCLUDING SPYWARE)

Do not Type in Google “Free Scan or anything like that…..Because it will just harm your computer more….

Try to get Norton Antivirus…I believe it Costs though..i am telling you now though, if you go to a random website, and let them scan your computer, it will just mess it up much more.
