1. Another keyboard.
2. Make sure VOICE COMMAND is turned off. Let's see if I can GOOGLE an article on this. GHOST CHARACTERS VOICE COMMAND DISABLE into http://www.google.com and I press the I'm Feeling Lucky key and viola...
Hopefully, one of the above helps you cure it.
In closing, good idea to scan or parasites. Have you tried the Anti-Parasite Suite noted at http://reviews.cnet.com/5208-6132-0.html?forumID=32&threadID=1313&start=0 ?
All of a sudden, yesterday, I found that when I type certain keys (specifically c d e) I get extra characters appearing with them - xc sd ew respectively. This happens in all programs. I have scanned for viruses with up to date definitions. If it is not a software problem, is it the case that my one month old keyboard (optronix) is at fault?
I'm running XP on an Athlon 1800+ 512Mb.
Any help appreciated, I'm sdicxk of wevwerything I typwe turning out likwe thisd!
