<human>:  How do I fix a computer virus?
<bot>: The best way to fix a computer virus is to use an anti-virus software program. It is important to have an up-to-date anti-virus program installed on your computer and make sure it is regularly scanning and updating itself. You can also use a virus removal tool to get rid of the virus if it is not detected by the anti-virus software. If the virus is not detected by either method, you may need to take the computer to a professional to get the virus removed.
