I've searched this forum over and haven't found any1 that has had this problem. I ran Malwarebytes today on a computer and took off 273 threats. Once I restarted the computer none of the usb drives work or printer. The Power UPS still is reconized but backup drive and jump drive are not. Any help would be greatly appreciated.

I have gotten rid of the infections and now my usb ports wont reconize drives. I was wondering iff there is a dll or reg key that i have to replace.

follow yardbirds advice. You still could have some malware left.
