Hello, I am having problems with two mice I own. The first one out of nowhere began lagging every so often then make a couple beeping noises. It got worse and worse, I initially figured it was malware, so I did a scan and removed one found virus. The problem persisted and actually got worse, to the point that it would lag almost always if I double-clicked. Then I had another mouse around my house so I used that one, however I knew it wasn't being used because it started to go along time ago, but I wasn't sure if it was from malware or not. I plugged it in and it seemed fine, but it is doing the same problem now, but with no beeps this time. I did some looking at other threads through google and found that it may have had a problem on installation so I re-installed/updated drivers and it's still giving me problems. I want to make sure it isn't something other than the mouse before I go and buy a new one. It's weird because now it basically never does it unless i'm playing a game (World of Warcraft). On both mice, (opticals), the light goes off for a second or two, then comes back on. When it goes off, it stops working. I tried changing the usb ports thinking one may have been damaged or something but the problem still persists. Any help?
