Sometimes My computer curser spins around in circles, and opens whatever menus it touches. Other times it locks up, and won’t move at all. And I have to reboot my pc in order to unlock it. I have a virus program called Yahoo online protection. {I use Yahoo internet. And I keep it updated. I was told to download Defener, but it didn’t help. I tried Yahoo online technical help, but no good. I’m pretty sure it’s not a virus. But I’m not an expert. I didn’t buy and set up this machine, and the ones who did won’t help. I can’t afford to take my pc to a repair shop, or replace it. While the curser spins around I can’t control it, and often get knocked off the intenet. It’s really ticking me off, because it is almost always when I’m in the middle of something. Any ideas? I’ll be thankful for whatever you say.
