PC performance drops significantly during antivirus scans, but monitoring shows minimal activity in Task Manager.
PC performance drops significantly during antivirus scans, but monitoring shows minimal activity in Task Manager.
Whenever an antivirus (so far this happened with malwarebytes and windows defender) is doing a scan in the background my gaming PC slows down ALOT more than it should (for example, it takes about a second to open files when normally it's instantaneous, and in minecraft my fps decreases to 30-40, absolutely unacceptable for these specs). And the weird thing is that I checked task manager while one of these scans was running but everything in there is below 10% usage (including disk usage). The only things I changed in the BIOS were the fan speed settings, but I ended up changing those back to their defaults. I don't remember messing with anything else in there. Any help would be very appreciated. P.S. This is a prebuilt PC from a local company that imports components and builds PCs for profit, so it's not a big brand.

Nothing wrong with that. Even if cpu is not used at 100% and drive is not used at 100%, it's still heavy job to read all files on drive, scan them, connect to network even (if cloud detection is enabled) etc. So it's not unusual that you see no 100% usage because nothing is used at 100%. You may expect drive 100% usage when you copy huge file at maximum speed, but not when you zip file (then drive usage will stay below 100% even if your computer works harder). It's always your choice - security or speed.
