My computer may have a virus - any help ?

FIrst of all you want to boot your computer into safe mode by holding the F8 key (This is all if you are a windows user if you are using a mac then this won't work) Be sure you are on safe mode with wireless enabled (the verbage used) other wise you will not be able to download the programs needed. (hold and keep pressing the F8 key while its starting up, so reboot it)

Then go to google and search for Spybot Search & Destroy, download it.
Once its downloaded, run a scan, then once scanned it will ask you if you want to fix all problems, click the okay, or yes...Can't remember which one. (This might take a bit, and make sure to select the Scan for problems button)

Then download and install Avira Free Anti Virus (google it), not as system heavy as AVG, run a scan of everything...In other words don't run any type of quick scan, then once all scans are complete, restart your PC as normal. It should be good to go.

Oh and also if you can, log in and change your email password if your account has been "hacked" and you can't change it, then contact your email provider for help. Hotmail, Bell, etc. As well change any other passwords like Facebook, google + etc
