If you do have a Macintosh computer, they are usually one of the best types of computers, especially over PCs, because they cannot be infected very easily by foreign software. If you do have a Mac, and you are noticing that it is running much more slowly than it has in recent days, it is possible that you have malware on Mac. To fix the problem, simply purchase software that can detect where these software programs are, and eliminate or quarantine them so that you can dispose of them. This is the best way for you to get things back to normal and you can do so for an affordable price.
