It's not PlaneShift

I recommend:
- Use Firefox as a browser, much safer!
- Get a good virusscanner. Use a good free one like Avast! if you don't want to buy one.
- Clean up after yourself after using the internet, use CrapCleaner.
- Use up-to-date spyware-scanners like Ad-Aware 2008 and Spybot: Search and Destroy.
- Obviously, keep Windows up-to-date at all times.
- Don't try to download all kinds of illegal stuff if you don't know what you're doing.
- Etc.
