When your computer slows down there are a number of different things that could be wrong.  There are a few common culprits that are typical for causing computers to slow down.  I strongly suggest that if you’ve started to have issues that you scan your PC with a tried and true malware removal software tool.  There are a few good ones on the market but the one that I always recommend to people is Spyhunter 4.  This software program from Enigma software is a great tool to help you to update your computer with the latest in spyware and malware protection.
