Removing a virus from your PC manually can be one the hardest kind of computer repairs. Luckily there are many different software programs out there that can help. To remove a virus you will need a combination of Virus software, Spyware software and a startup manager piece of software. These three are still not enough. You need to know the right process in which to run the software pieces to remove the PC virus.
The good news is we have the process right here to repair your computer. We will provide a few free programs but recommend you actually go out and purchase a good all in one security suit. The first thing is to boot normal. Once logged in you will need to turn off the system restore. The reason for this is because many viruses will hide in this area. Now reboot and boot into safe mode with networking.
Once you are booted into safe mode with networking you will need to download, the free AVG anti virus, Spybot Search and destroy, highjackThis, and ad-aware. Install all programs and then update them. Now download CCleaner, install and run. Remove all those junk temp files. Now run ad-aware and Spybot. Both programs can run at the same time. Once they finish reboot normal, if you were asked to run Spybot again on boot then let it run. Now run AVG and do a full scan.
One AVG has finished then reboot and run highjack this. Remove any entries that you know to be bad. Be careful and only remove the known bad entries because if you remove something that is needed you will be hosed.
If you are unsure about any of what was said here then your better off having a pro remove the virus. This can be done for as little as $89 dollars on places like http://www.onlinecomputerrepair.org. We recommend you purchase anti-virus software as well because the fact you were infected in the first place tells me you were not protected enough.
