I am running Win XP. I opened my computer this afternoon and the screen was full of malware saying my computer was infected and buy thier removal TOOL. I could not open any programs or even use the keyboard. I restarted in safe mode and did a system restore for 2 days ago and everything looks OK except the keyboard wont work. It will work when I go to CMOS but once windows loads it wont work. The lights come on but none of the keys will work. Some of the hot buttons work. I have uninstalled through the device manager and keyboard in control panel and restarted. There is a screen that says that computer has detected new hardware and so I want to install, I click yes reboot and it is still x'ed out with a yellow exclamation point in device manager and won't work. I did troubleshoot and get this.
"Windows cannot load the device driver for this hardware because a previous instance of the device driver is still in memory. ( Code 38)"
Can anyone please help, I have done the uninstall and reboot ten times and same result. Thanks for any and all advice.
System restore does not delete malware. You should go to the malware forum on this site and follow the instructions in the FIRST pinned post.Hi,
    Please follow the below mentioned steps to run an ANTIMALWARE software to remove malware from your computer. As it seems to be a malware issue.

1). Download malwarebytes from below link:

2). Install it and run a full scan for your computer.
  (Make SURE while running full scan you are not connected to internet)

3). After running scan delete all the infected files and data.
4). Restart your computer and check the boot up speed.
 Everything should work fine.pcs365_2:
