my mcafee live antivirus is expired.
I'd suggest using a better antivirus. McAfee is generally considered to be one of the worst antivirus, if not the worst, and the only reason people use it is because it comes pre-installed on so many computers (McAfee pays the computer companies to include it -- as a form of advertising). Often it's just a trial version that expires in a month or so.
If you want suggestions for a new antivirus, start a new thread with a new title that indicates you're looking for suggestions for an antivirus (not the name of a game).
You can also do a Google search for "Best Free Antivirus 2014" to get ideas for free antivirus. Or if you don't mind paying for the antivirus, Google "Best Antivirus 2014."
Be sure to uninstall McAfee before installing a new antivirus. Also run the removal tool for McAfee (
***MCPR.exe***) to get rid of any remnants of McAfee that the regular uninstall may have missed, and which might conflict with another antivirus.
After uninstalling McAfee, if you haven't already chosen a new antivirus, make sure Windows Defender is active on Windows 8. On Windows 8, you can just use Windows Defender as an antivirus. It's built into Windows 8. It's not the absolute best free antivirus, but it's completely free, doesn't expire, and doesn't nag you to resubscribe every year. If you decide to use Windows Defender as your antivirus, you may want to use it along with MalwareBytes or another anti-malware program (not antivirus) along with Windows Defender.
