Don't click on the virus, just leave it.
1. Start your computer in safe mode by restarting your computer and hitting F-5 or F-8 over and over until a boot selection pops up.
2. Select - Boot in safe mode with networking
3. Once logged in, go to your browser and make sure it's working. If it's not working, you'll need to go into the internet explorer --- tools --- options. Under the 'Connections' tab, click on the 'LAN' settings.
4. In the LAN settings make sure 'automatically detect settings' is clicked and 'use proxy server' is unclicked. Press Ok.
5. Go to google.com and find these three programs (Type them in google to find them): Superantispyware, malwarebytes, Microsoft security essentials.
6. Install all three programs, update them and run them. If they won't run in safe mode, run the ones that will run in safe mode, delete all viruses they find and restart in normal mode and run the programs that wouldn't run in safe mode.
After that's done, most viruses will no longer be on your computer.
