I'm not sure what's wrong with my computer. I have run antispyware software and the results conclude that there are no threats. However, my cursor moves when I type, jumping all over the place and even deleting words/lines (it's not because of the insert key), and my computer has been running rather slowly. Also, sometimes I get the result "web page is unavailable" when I visit various sites. Actually, the fact that my computer runs slowly may be due to the fact that I have too many protective programs. The following are installed: Avast Antivirus CCleaner AdAware AVG Free Advanced System Care SuperAntiSpyware MalwareByte's Anti-Malware I'm not sure which ones are unnecessary. Can you suggest which ones to uninstall?
