Mouse not recognized after boot scan cancel

I received a malware alert about 2 files from my avast anti-virus, it recommended that I press OK to delete them, I did, and then it said something about a " boot scan " and I pressed OK, my system started to restart ( I realized what a boot scan was, haha ) then instead of the usual boot up things with the logo and stuff it started a scan, since I knew those 2 files were not malware I canceled the scan and Windows started, but the screen was darker, taskbar was back to classic style, sound was disabled, the wi-fi icon didn't even appear, and my usb mouse was not working but my phone was connected and charging, I couldn't do some things like adjust the brightness, etc. After I went to dr. Google in order to find a fix I found a forum thread and the recommended fix was to go to msconfig, services tab, and check enable all. Indeed my services were all stopped except for the Avast Anti-Virus ones, I enabled all, restarted, everything returned to normal except my mouse which is not working at all, no lights as well. (Had problems with this when mouse's under light and clicks were working but the cursor was not moving ) . My phone connects through USB normally. Everything seems to be working normally except for my mouse. Connected it to other PC's and the mouse works normally there.

EDIT: I found out that there is no USB Mouse driver in device manager, only the PS/2 one.

Try plugging the mouse into a different USB port. Also, try another mouse.

Do you have any USB errors showing in Device Manager? Right-click on the top item of the tree, and tell it to show legacy/hidden devices. If any of the listed devices show errors, right-click on each one and uninstall it. (One of these may have been the one that your mouse was using.) Then right-click on the top item and tell it to scan for new hardware devices. Hopefully it will correctly load the driver associated with your mouse.

I have had USB go out in two computers in the past several years, causing my keyboard and mouse (and in one case, my USB wifi adapter) to quit working. In both of these cases, I had PS/2 ports on the computer, so I scrounged up a PS/2 keyboard and mouse, and I was back in business. (I ran an Ethernet cable to the one where my wifi adapter quit working.) Once I got a working keyboard and mouse, I was able to fix the USB problem.

I have a laptop. No PS/2 ports.

Also, there are no USB errors showing in the device manager. But as I said, connection with my phone works, file transfer, charging and everything else. And the mouse works with other PC's.

Try a different mouse with this computer. Also, plug it into one of the USB ports which does work.

The reason I suggested a PS/2 mouse is because you said that there was a PS/2 mouse device showing up in Device Manager. But since there are no PS/2 ports on the computer, that driver could be the culprit. Delete the PS/2 mouse device and then scan for new devices. If the PS/2 mouse device shows up again, then I suspect that there is some issue with your current mouse, even though that mouse works on other computers.

Your mouse may be both a PS/2 and a USB mouse; perhaps that is why there is a PS/2 driver.

Other USB mouses work fine.

When I use other USB mouses there is a new driver in the device manager at the mice tab, when I remove the mouse it disappears. Will try to delete the PS/2 driver.
