I am using windows xp sp3, and finally got a virus. I will deal with that in the appropriate forum. I am not typing from my own pc, because my browsers do not work despite the fact that my pc says my connection is working. I am at a relative's house.
Please bear with me, as I try to remember what I did that disabled my mouse. I was foolishly looking around my pc, to see if there's any obvious nefarious program that doesn't belong there. Big Mistake. I should have done nothing, and came for malware help at the time. One of the places I looked at for some reason was the device manager. I saw a device that I've never seen before, and I have not installed any hardware in a long time. To the best of my memory, it was some sort of "USB Human interface device", with 3 sub items. It has an icon that I NEVER saw before, so it got my attention right away. My mouse device still showed my correct mouse with drivers as working. My keyboard also showed up with proper drivers as working. So I became suspicious that this was possibly part of the virus that has taken over my PC.
Obviously I was wrong, now that I can do a search it seems that this is a genuine device driver, although I don't know how it got onto my PC, and why. The sub-items below it had an option to "disable". I figured I'd try to see if disabling this unknown "thing" would free up my browsers to work again. Desperate people do dumb things sometimes. I know better than to touch things when I don't know what they are. I ALWAYS research things before changing them. But I was locked out of researching, and I figured it would be reversible... so I clicked on disable for the first item, as you figured out, I disabled my mouse. The item completely dissappeared, so now there are only two items left. One of them now has a red mark. Apparently these drivers were controlling my mouse and keyboard in place of the drivers I've had on my PC for years.
I am going to go back and try to see if I can get back to the device drivers using keyboard controls of the mouse. I can not download anything onto my PC, because my browsers are incapacitated by a virus that has also locked me out of two backup malware detectors that I have. Again, that problem I will deal with. But I need to get my mouse working again. As I said before, the Mouse Device shows that it has a driver for my mouse that is working. Assuming I can move around using my keyboard, is there any way to redirect my pc to use the driver it always used? Should I completely delete this USB Human Interface device? Will that cause my computer to consider my mouse to be new hardware, and assign it the default generic driver - or even the driver that is installed and "working" right there on the device list under the Mouse device?
What can I do??
