First off, check in at Windows Update to install all updates & patches
offered.

All the latest patches and updates of Windows 2000 have been applied but did
not help.
Also forgot to mention that I am not able to login to any https site(besides
yahoo) using my browser.
Request if you can help me out.

When all else fails, HijackThis v1.99.1
(http://aumha.net/downloads/hijackthis.zip) is the preferred tool to use.
It will help you to both identify and remove any hijackware/spyware. **Post
