As of a few days ago, my computer is behaving 'erratically'. When I am typing, my pointer will randomly move to another place in the text and start typing a semi-random string of characters. ("gvyfn" is common; It has typed this about 8 times whilst I composed all the text above) It often highlights part of or all the text and overwrites it. It sometimes goes into loops of pressing Control-alt-delete down, bringing up Windows 7 menu thing.

It sometimes even messes with mouseclicks; they have unexpected results, like requesting admin priveledges from applications, instead of switching to their window. I believe this is because it is holding a alt-function key down.

This behaviour happens periodically, in waves. It might subside for an hour, then continue to haunt me. I believe it to be a virus or malicious program. My anti-virus (Symantec) and multiply MS rootkit removers could not find anything suspicious.

I've noticed that sometimes it re-maps keys, and types gibberish when I press certain keys (though no pattern is evident).

I believe a malicious program has installed a keyhook on my computer.

I'm wondering...
- Is there a way to let me view which programs are emulating keystrokes?
- Is there a way to view what keyboard hooks are installed?

(I'm also at liberty to try any other techniques to remove this blasted thing. It is easily the most fustrating computer problem I've encountered). Thanks!
