According to users, sometimes antivirus software can cause slow file transfer speeds on your PC. Third-party antivirus can sometimes be quite invasive, and that can lead to this problem. However, you might be able to fix this problem simply by disabling certain antivirus features. Alternatively, you can try disabling your antivirus altogether.

If that doesn’t work, you might have to remove your third-party antivirus. If removing the antivirus solves the problem, the next step would be to switch to a different antivirus. One reliable antivirus that won’t interfere with your system is Bitdefender, so if you’re looking for a new antivirus, be sure to try it out.

Several users reported that Windows Defender can also cause this problem, so if you’re not using a third-party antivirus, try disabling Windows Defender and check if that helps.


Solution 2 – Run Hardware and Devices troubleshooter

The most common cause of this issue is your motherboard drivers, so be sure to visit your motherboard manufacturer’s website and download the latest chipset drivers for your motherboard model.

If you don’t want to search for drivers manually, or if you simply can’t find the suitable driver, perhaps you might want to try using TweakBit Driver Updater.

After you update all your drivers, the issue should be resolved and everything will start working again.

Solution 8 – Check your BIOS

If you’re encountering slow file transfer speeds on your PC, the problem might be your BIOS configuration. Several users reported that their hard drives were configured as IDE drives in BIOS, and that caused the issue.

In case you don’t know, IDE is an older standard, and by using it with newer hardware you might encounter various problems. However, you can fix the issue simply by changing the hardware configuration from IDE to AHCI in BIOS.

To see how to do that, we advise you to check your motherboard manual for detailed information.


Solution 10 – Connect the hard drive to a different port

If other solutions didn’t work for you, perhaps this is the good time to check your hardware. Several users reported that a SATA port can sometimes cause this issue to occur, and in order to fix the problem, you just have to connect your hard drive to a different SATA port on your motherboard.

After doing that, check if the problem is still there.

Slow file transfer speeds can be quite annoying, but we hope that you managed to solve this issue by using one of our solutions.
