If you want my personal and professional opinion - what I tell paying clients, family, friends - I would recommend removing McAffee and just use the built-in Windows Defender. The OS tries to prevent this and usually does a good job. And now every part of the machine is busy, only causing it to get even worse, so the problems compound until something finishes (which was already busy opening files for the antivirus to scan) now has to also go save the paging file (temporary memory file). The CPU has to do all that work, and the harddrive Then Windows has to start taking things out of memory and putting them on the disk temporarily to make more memory available. Then no matter how aggressive the antivirus gets, it's still lower on priority than the stuff you're doing (scrolling, using the PC,Īnd again if your memory is >80% used or so, that could also be a problem. It's like a car, there's many parts that have to all work together to perform the best.Īnyway, if it's stuttering and lagging when you scroll, and you're not very low on memory, then it's quite likely the CPU is the one causing the bottleneck (probably the deep-scanning of every file by the antivirus, rather than the actual disk activity itself).įor one example, you could right-click the process of the antivirus (on the details tab) and change the priority to low. Please feel free to reply in case you face any other issues with Windows in future.īeing able to scroll doesn't require the disk unless you're very dangerously low on memory already.

If you're connected to the Internet or a network while your antivirus software is disabled, your computer is vulnerable to attacks. You should re-enable it as soon as you're done.

If you have to temporarily disable it to install other software,
In most cases, you shouldn't disable your antivirus software. Important: Antivirus software can help protect your computer against viruses and other security threats. Step 2: If the behavior is same, disable the security software and check.

Note : Refer " How to reset the computer to start normally after clean boot troubleshooting" to reset the computer to start as normal after troubleshooting. You need to follow the steps from the article mentioned below to perform a Clean Boot. Placing your system in Clean Boot state helps in identifying if any third party applications or startup items are causing the issue. This kind of startup is known as a "clean boot." A clean boot helps eliminate software

Step 1: To help troubleshoot error messages and other issues, you can start Windows by using a minimal set of drivers and startup programs. I would suggest you to perform clean boot and check the status since this could also be due to any third party software conflict. Shawn "Cmdr" Keene | Microsoft MVP - Windows Insider | | tweet: Microsoft MVPs are independent experts offering real-world answers. It can't be "full" like memory or CPU usage can be, but this value is estimated based on how much the disk is being used. If my memory was up at 85%, my computer might begin to lag because then it has to start using the disk, but several programs are already using it, and the disk head can only move around so fast.ĭisk "usage" is a funny thing. I'm not listening to music or have anyĪctual files open, and it doesn't take much memory for me to type my reply. Now in this case, my computer is still pretty snappy because I'm just typing in a browser, and that doesn't require using the disk. I ran a virus scan and told PowerShell to move a bunch of files at the same time.
Click the Disk heading and see which programs are using the disk. To see and answer both of these, just press Ctrl+Shift+Escape, and look on the Processes tab. Program using it, even a small amount, makes the computer performance slower, and you'll see this much worse if some of that disk activity is because of "paging", or putting things from memory to disk because there's not enough memory at the moment. Is the antivirus program responsible for all of the usage, or is it spread out among several programs causing the disk activity by competing against each other? Since the hard drive has a moving arm that literally has to move back and forth, more than one
