Ordinarily I don't touch Microsoft computers - they just aren't user friendly. But when my iBook melted its logic board yet again, I found myself working with the family computer.

Through a sea of program and document icons on screen I found Internet Explorer. And after a while I noticed the search results in Internet Explorer with Google differed from the searches in Safari, Opera, FileFox, or Chrome. For example a search for Ask Jeeves in every other web browser returned:

http://www.ask.com/

In Internet Explorer a Google search for Ask Jeeves returned this instead:

http://216.195.52.100/go.php?c=TsuW...o/oNFVL8WuLo7UdqsC9w=+rfr=gsso`~~onqmanzqc^tr

I decided to find out just what this 216.195.52.100 business is about and found this web site – The Fire – that suggested I had a bug somewhere on the machine. My searches using the find function under the Start menu turned up nothing – no tiny flash files anywhere on the computer. Just to be sure, I downloaded Avast antivirus software, ran it, and after a week of daily scans, I found nothing.

I also noticed another problem with Microsoft Word. It took two minutes or more for a new blank document to appear. I began searching for reasons why the program was so slow and I ran across this web site – Rootkit Revealer. I decided to give the program a whirl.

Many things showed up – such as files with very long very descriptive names. But nothing bad except for one lone file near the bottom of the list.

C:\Program Files\Common Files\System\k_rmpfrd32.dll 17.50 KB Hidden from Windows API.

When I searched for it I couldn't find it. I booted up in Safe Mode and I didn't find it. Then I booted up in the lowest mode possible in Windows – command line prompt. After typing a lot's of CD and double periods, I found the file, moved it up to the C directory, and restarted.

Every time I click on this file – Avast lights up like nuclear missile launch. :covereyes

As a side effect, the problems with Internet Explorer searches vanished. Also Word managed to load a new blank page in two seconds. Oddly, upon scanning with Rootkit Revealer again, two files disappeared from the registry:

(1) \Local Settings\Application Data\Microsoft\Messenger\xxredesignedxx@hotmail.com\SharingMetadata\cosmicburst@hotmail.com\DFSR\Staging\CS{0D72DE90-FB8C-E008-53E6-42952A3CA5B4}\01\10-{0D72DE90-FB8C-E008-53E6-42952A3CA5B4 – 8 bytes – Hidden from Windows API.

(2) \Local Settings\Application Data\Microsoft\Messenger\xxredesignedxx@hotmail.com\SharingMetadata\cosmicburst@hotmail.com\DFSR\Staging\CS{0D72DE90-FB8C-E008-53E6-42952A3CA5B4}\20\20-{92252387-ECE9-4D07-84AE-DF63D1D64720 – 80 bytes – Hidden from Windows API.

I cannot tell what they do. But I've discovered two other suspicious files.

HKLM\SECURITY\Policy\Secrets\SAC* – 0 bytes – Key name contains embedded nulls (*)
HKLM\SECURITY\Policy\Secrets\SAI* – 0 bytes – Key name contains embedded nulls (*)

I haven't fooled with them. Not exactly sure what they do. But the mouse occasionally drifts upward for no reason, the screen slowly dims and brightens up once and a while, and the keyboard occasionally ignores the shift key. :boggled:
 
Those last two are legit. As for the problems you're having...
1) optical mouse with a strong light shining on it?
2) CRT monitor on its last legs?
3) keyboard needs cleaning?
 
Those last 3 problems combine into one possibly very big problem: aging motherboard. Turn the pc off and look at it. See if any lines are gold-colored on one part but gray on another.
 
That sounds awesome, but when I scan all I get is "C: 0 bytes, error mounting volume"

I think the keyboard might need cleaning, but it may just be badly made – shifting occurs more to the center than the edges. I think the CRT or the video board may be bad – I’m thinking about switching monitors. The optical mouse doesn’t have any bright lights shining on it – maybe a mouse pad would work.

I hope not. I’ll have a look.

Strange. Maybe you’re running Vista and they changed things.
 
I had similar problems with my board a lot of weird symptoms.
I found some bad capacitors on my board.. Look for bulges
or if the capacitors tops seems to pop up. They should be flat on top.
Is this an really old computer ?
I try and always clean my system, temp files, caches etc.
I should have bought a new board but I soldered in new capacitors.
