Hi, I installed a driver (.exe) for my Ajazz AK820 keyboard (the file was around 40MB). After installing it, my PC started behaving strangely: the storage filled up completely, apps took a long time to load, the disk was constantly at 100%, and the volume wheel stopped working properly — for example, scrolling it while pressing the Windows key would cause Windows Explorer to restart on its own.
I rebooted but the problem persisted, so I assumed the driver was the culprit and uninstalled it. Here's the concerning part: before installing the driver I had 12 GB of free storage, but after uninstalling it I lost almost 50 GB (I had to force-close the uninstaller). After uninstalling it I tested the keyboard again and the volume wheel works fine, apps load smoothly — everything seems to be back to normal. So my question is, is it possible to find out which files were deleted?
Could it be a serious virus? Should I reinstall Windows? I checked my email, Discord, Steam, and other accounts and everything seems fine — nothing was logged out or anything suspicious. I also scanned it on VirusTotal but nothing was detected
