In addition to what has been posted above, an analysis of your HJT log shows the following problems :
We couldn’t detect any active process of a firewall on your system. Possible reasons:
(1.) You are using the windows firewall or a hardware firewall.
(2.) You are using a firewall of an unknown vendor.
(3.) You are using a firewall, but for unknown reasons it is disabled
(4.) You don’t use any firewall at all.
We recommend you to use a firewall. Download and install one or activate windows xp´s one way firewall that provides inbound protection only. A 2-way firewall that provides both inbound and outbound protection would be better.
Platform: Windows XP SP2 (WinNT 5.01.2600)
As noted above, newer version of service pack is available. Service packs increase the safety of your system. Visit Microsoft’s windowsupdate site to download the newest version of the service pack.
MSIE: Internet Explorer v6.00 SP2 (6.00.2900.2180)
Very outdated and very insecure version of IE. Also noted above.
