This is the result my HJT Log Analyzer (freeware) is giving:


CHECKING HIJACKTHIS, INTERNET EXPLORER, WINDOWS AND SOFTWARE FIREWALL:

You are using the latest version of HijackThis.
You are using the latest version of Internet Explorer.
No software firewall detected. If you are not using a
hardware firewall, it is highly recommended to install one.


THESE ITEMS ARE HARMFULL AND SHOULD BE FIXED/REMOVED :
