USB devices aren't working and Malware

I have 2 Lenovo machines Yogo 260 and X230 both have USB ports that recognize devices however, don't load drivers for them to work.  Simply put, they know what's been plugged in, but the device doesn't work.  I've tried  Aalwarebytes, AVG in case virus related.  I've downloaded and installed Windows and Lenovo updates.  To no avail.  NOTE:  1 has been detected to have Gen:Trojan.Heur2.LPTEG0@b4M@6uib, Trojan.Generic.17862579 and Application.HacktoolKMSActivator.AK.  The other with Application.Hacktool.KMSActivator.AI.

Please help.  Are malfunctioning ports related to malware?  What do you recommend?  Thanks!

I have an X230 here running Windows 10 Insider and USB ports all work fine.

Update BIOS, Chipset, Video and all other drivers (Lenovo Update in Control Panel).  Update Windows and test.

This is plausible, though I've never seen it.  A malware writer certainly wouldn't want the victims sticking in uninfected USB devices containing the portable version of Malwarebytes.

Simply put, they know what's been plugged in, but the device doesn't work.

Then the USB ports are functioning, and there's a problem somewhere in software.  There's only four wires on a USB port and the hardware can't "half work."  Possibly there's a problem in the installed antivirus, possibly due to a recent Windows Update.

Try disconnecting from the internet, completely disabling the antivirus, then reboot (still disconnected) and see if the problem persists.

If there is a Restore Point available made before the problem occurred, use the Restore Point and see if the problem is alleviated.

If you get to this point and the problem it still not resolved, then decide whether to continue troubleshooting the problem or use brute force and eliminate it.

If there's no Restore Point or using the Restore Point fails to eliminate the problem, save any files recently changed to a temporary files site on the internet.  Then erase the drive using a product such as Darik's Boot and Nuke or Active@ KillDisk and restore the system from the most recent full backup.

Thanks John but it didn't work.  Actually tried that prior to posting.  As a matter of fact, Lenovo update didn't catch everything.  After I updated via Lenovo Update, displaying all devices through Device Mngr. and right clicking on EVERY device, Windows updated an add'l 5 devices...but still no luck.

Take one of the machines (say the X230):

1. Make a new, test, Windows User Profile (Account). Log into the new Windows Account and test USB.

2. If that does not work, try a non-destructive Windows 10 Repair Install and Keep Everything.

Windows 10 is running, so click on the Download button (not Upgrade Button, select Open (Run) but NOT Save. Allow the program to run. Allow drivers to update. Then select Keep Everything.

As noted I have an X230 here and these updates did not affect my USB ports.  I know other machines are different.

Pull the disks and scan them on a working system.  If you're unable to clean the disks, then you should back up the data and reinstall them.
