My laptop has a virus. What is my best course of action to try to remedy the problem?

Which virus? Run a few online virus scanners and see what all they come up with, tell us how bad it is.

Hi,
First End the process from windows task manager( which is running for virus). Then download & install Malwarebyte and Superantispyware on your computer and scan your computer throgh Malwarebyte & Superantispyware.
