Thanks for your help. I don't know if anything will turn up, but I've had a few problems with the computer recently and I've tried pretty much everything else I can think of, so I thought I'd check using HijackThis to see if anything showed up.

Well, I seem to have started having problems after going on YouTube.com last week - which might be telling in itself. Are there any well-known problems associated with the site?
Firstly the computer monitor switched itself off and on again and the picture went extremely large and then returned back to normal. The computer then restarted on its own - could be a power surge?
But a few minutes later when I tried to open a bbc webpage to view a film in realplayer, realplayer crashed and so did internet explorer. This has never happened before, as I use realplayer a great deal. The error report said I should try http://service.real.com/realplayer/ which advised me to Lower the hardware acceleration. Which I did. And realplayer started playing fine but from then on every time I switch on the computer I get an error message from Hydravision. And the computer can run rather slow when I have more than one application open at once, which never used to be a problem.
I've run AVG, Spysweeper, Adaware, CCleaner, HijackThis, WindowsDefender. And can't find a problem anywhere. Am I missing something obvious?
Download F-Secure Blacklight (blbeta.exe) to the desktop from here.
Open it and click Accept Agreement.
Click "Scan".
After the scan is complete, click "Next", then "Exit".
It will create a log on the desktop named "fsbl-xxxxxxx.log" (the xxxxxxx will be the date and time of the scan)
Post that log in your next reply.
Go here to run ActiveScan.
After downloading, click My Computer to scan.
When it finishes, click "See Report".
Click "Save report" and post it along with the BL log.

Blacklight came out clean. Panda didn't find the usual. There a few adware registry entries, but Panda isn't showing the location so we can remove them manually. You'll need to let Ad-Aware delete them. SpySweeper may remove them too, so run a scan with either or both.
About the first problem: try uninstalling then re-installing Real Player to see if that helps.
