Remove Win32:Rootkit-gen[Rtk], but Windows XP doesn't restart correctly.

Hello,
With AVAST, I have been able to remove the virus, but now when I restart Windows, it takes 10 minutes before I can work. During that time all is blocked, I cannot access the start button. After 10 minutes, it works properly. Before the virus, I had not this problem, the computer starts normally.
I guess that are some remaining parts of the virus, can you please help me to check if there is still the virus and how I can remove it.

Thank your for your help.

Check your computer for Malware with

after install click UPDATE and run quick scan, click on REMOVE SELECTED to quarantine anything found

SUPERAntiSpyware http://filehippo.com/download_superantispyware/
Are cookies really spyware and are they dangerous?

I run Malwarebytes Antimalware and remove all the files in quarantine.
