Welcome to Bleeping Computer.
Your log is clean. Frankly I am rather amazed to see this, because your machine is wide open to infection.
Here are the main problems:
I can see no evidence that you have any antivirus software installed. If this is the case, you need to install an antivirus program immediately. Please download one of these free programs:AVG Free
is available at this site
.Avast Home Edition
is available here
can be downloaded here
I personally use AVG Free, but all these programs have good reputations. If you don't like one, you can try another. Please consult the help files or online support for information on installing, updating, and using the program.
Another issue is that I see no evidence of a firewall on your computer. It is important that you use a software firewall
, to prevent unauthorised traffic both out of and into your computer. I recommend you download and install one of these excellent (and free) products: Zone AlarmSygateOutpost Firewall FreeKerio personal firewall
For more information about firewalls, please read this tutorial
And finally, your Windows installation is badly out of date. Microsoft does not support SP1 any more, and it has numerous security risks that have been exploited by malware writers.
Please go to this web page
where you will find links to information on Service Pack 2 and ways to obtain it. Your basic options are either to download, which is practical if you have a high speed internet connection, or else to order the CD, which is free except for a shipping charge.
The Windows update is just as important as getting a firewall and Antivirus program installed. Until you get your operating system up to date, you could (for example) get an infection simply by visiting a malicious website -- you would not have to click on anything.
Please take care of these issues right away. Then run a fresh HijackThis scan and post the log to a reply here, and we'll look into your question of unneeded or unwanted processes.
