A few weeks ago, my computer starting getting an error message saying that 'superfetch is disabled' and suggesting I check online for a solution to fix it. It only appears when I first switch on the computer. After about half an hour of surfing it doesn't appear. The computer is taking ages to boot up and the internet browser page keeps 'twitching and jumping'. I don't know how else to best describe it. I use Firefox as my browser generally, but the same thing happens with Internet Explorer. I'd never heard of 'Superfetch' until recently and don't know what it does when its working. I'm not great when it comes to computers. Any advice would be really helpful. I've had the computer for about 2 and a half years. I've run CCleaner to clear out something (not too sure what). No problems with virus or malware at all.
