Just wondering if anyone has seen this before. I’m working on a student’s laptop. It had one of those rogue Antivirus Malware threats on it, which I removed using Malware Bytes. Now somehow, the laptop’s track pad  and keyboard have been disabled in XP. I initially thought there was a physical problem; but the internal keyboard works in the bios, and external keyboard and mouse work just fine in Windows.  Has anyone ever seen the like before? At this point, I’m pretty much stumped.

Thanks,

Al

 

Unfortunately, you have not removed it.

I had that about two months ago on a friends machine, and used
stuff to remove it, and it came back, all on its own.  Manual digging
revealed that it hid a copy of itself in dllcache, such that it was
able to defend against things like MWB.

Yes, I have seen the keyboard go, but not mouse.  Kind neat, killing
all normal input.

Some of this stuff is just brilliant programming.

Me, I'd scrub the machine.  I do not think it is possible to get some
of this stuff off machines.  Or, it *is* but at an incredible cost in
terms of time.  My department chair had a virus which emailed
copies of itself, a few years ago.  He managed to get the virus part
off, but the little smtp engine was still there, flopping around like a
fish out of water, creating these tiny temp files for each smtp
session.  It didn't send anything, but created thousands of files.  I
decided to fight this thing myself, and kept track of my time.  It
took 39 hours to do that.  I won, but I think it was something of a
Pyrrhic victory. 

Sorry to be depressing, but I've come to the conclusion that there
are several viri which you just can't reasonably get rid of...
