Ok, here's the result

Your HijackThis log appears ok. Have you ran AVG Anti-spyware (in the Prework)?

I haven't got AVG Anti-Spyware. Can you do a free scan online?

Funnily enough, since I cleared out all the logs on PCEye2000 it's been fine

If you want a free online scan:
You can try Panda ActiveScan.

• Once you are on the Panda site click the Scan your PC button
• A new window will open...click the Check Now button
• Enter your Country
• Enter your State/Province
• Enter your e-mail address and click send
• Select either Home User or Company
• Click the big Scan Now button
• If it wants to install an ActiveX component allow it
• It will start downloading the files it requires for the scan (Note: It may take a couple of minutes)
• When download is complete, click on My Computer to start the scan
• When the scan completes, if anything malicious is detected, click the See Report button, then Save Report and save it to a convenient location. Post the contents of the ActiveScan report.
