I have recently bought windows xp pro sp3 and it was working fine but after few days it give me errors like.

1. firewall does not turn on, and after when I turn it on it will off automatically.

2. I am working in Admin mode but it doesn't allow me to open task bar and regedit and says restricted by administrator.

3. Few Sotwares get currupted.

Please tell me what should I do..and how to remove these errors.

It could be some malware so keep the internet disconnected on that comp as far as possible. Which antivirus are you using? Download HiJackThis, scan with it and post the scan log here.

If it's due to some malware, you will need the following to fix it:

Kaspersky Antivirus 2009 (v8.0.0.454 trial)

SuperAntiSpyware (free)

Malwarebytes' AntiMalware (free)

Spybot Search & Destroy (free)

If the problem is not due to malware then a scan with Spybot S&D will fix the task manager and regedit problems.

Yes, a scan using Malwarebytes' AntiMalware (http://www.malwarebytes.org/mbam.php) would help!
