with NVT Malware Remover Tool click on “Settings”, then enable the option “Clear BHOs (Browser Helper Objects)” and then re-click on “Scan Button” to re-scan your pc.

After, restart your PC and try to do again a search and let me know if now is all fine.

Anyway, you can also post a log of HiJackThis just so we can analyze the logs and we can let you know if you need to remove other possible malicious files.
