    erratic behavior

    I have a desktop XP. It was working perfectly until last night. I ran malwarebyte and found three trojans and two registry keys. Earlier the same day I ran malwarebyte. It was a good health bill. All the trojans were associated with ccleaner 3.3. I removed those and it worked for a while then it started to behave uncontrollable. If I click on firefox shortcut, or any other application or a file it opens dozens of instances each in its own window. I restored an image I created a few month ago when the PC was working perfectly well. The computer worked well for a short while then the keyboard stopped working. I bought a new keyboard, the same stanza. Any suggestion what that could be?

    It's all over the internet this week about CCleaner having been hacked.

    Here is one example: https://securitybrief.co.nz/story/cc...alware-attack/
    U+00BD
    <p>&#x02BC;</p>

    code 39: '
    U+02BC: ?
    U+02BC: '

    You may also want to try Combofix HERE.
    It's not the computers that keep having problems, it's the users!!

    I am aware of the CCleaner issue. I fixed that. The new problem is with the keyboard.

    The computer works well with the mouse. The issue appears with the keyboard. For instance, if I press letter D, the application I am working with closes. I restarted it, now pressing D displays D. It works for a short while then it goes RIP. The new keyboard acts the same way. What could caused the keyboard to behave that way

    Avast Piriform says that hackers infiltrated its update servers to inject malware into a recent CCleaner release, but the issue has been resolved before any known attacks.

    Reset the BIOS to factory defaults first.

    Then check to see if the same problem occurs when running in Safe mode.

    If no, then that could point to a problem with software that runs in 'normal' mode but not Safe mode.

    If yes, it could be a hardware problem.

    To find out, boot from a Live CD|USB such as Knoppix and see if the same problem occurs.

    If yes, and if possible, try plugging the keyboard into a different port ... one that's directly connected to the motherboard (of course).

    If the same problem is still occurring, starting to sound like it may be a bad motherboard.

    Let us know what you find ...

    Another way to reset the BIOS is to remove the BIOS battery for a few minutes, then re-inserting it.

    The keyboard "was" or "was not" responsive?

    the keyboard responds for a few strokes and then it goes belly up. The same thing happens with the new keyboard I just bought.

    I have a PC handy, I don't know if I could use it on a laptop, I am not sure about it. Now the computer complains with the message "active partition not found". I boot up with macrium rescue CD, everything work fine with the mouse, I restore the image, the problem persists
