There are two ways to remove viruses from your computer:
1. You can download and install a paid or free version of a certain antivirus on the internet and scan the computer after installation.
2. There are some tricky viruses that will not let you install an antivirus much less let you perform a system scan. So to remove it, the only thing that can be done is to back up your files and have your computer reset back to it's factory defaults to clear and clean the hard drive.
