Hi,

wow nice catch

.
Let me add a few things to this thread which provides nice info about some things.
Adware/Spyware :-> not always bad ........Spyware is considered bad but Adware sometimes Come bundeled with the Freeware programs you download it's a way to put Advertisments into it........they have to earn some money too .
You can use AD-Aware and Spybot to remover.
and all you find with them is not bad ................i have seen a few useful programs start to stop working after you reove the Adaware in them........like my ISP had Gator Advertisments in it AD-Aware remover the gator Ads and it stopped working.
Scumware as you put it includes everythig that is bad ( Virus , Trojans , Worms and Adware/spywares too ) it is also called malware.
P2P and P0rn are the major sources of Scumware ...............the programs you donnlwoad form P2P might be bundeled with a virus or trojan you just can't trust it so try to get it form the Authors Web Site.
For Virus you require an Antivirus .....................but one thing to remember is Antivirus are not particullarly good when it comes to Trojans and worms ..there are plenty of free of them as said earlier AVG Free Edition is the best according to me .
For Trojans and Worms i don't Trust Antivirus they catch a few of them but fail most of the time....... i would recommend Download TDS-3 Anti-Trojan System and Moosoft the Cleaner ..................TDS i think is the best .
And Updating Your Windows is also important................ Microsoft launches Security patches regularly .................hackers and trojans use holes in your OS to attack your Computer .............Microsoft tries to patch these holes as soon as they find them so pressing that Windows Update button on a regular basis is not a bad thing at all or you can Click on this link to update your Windows Operation System update your OS regularly.. -->

and there is one another kind of Scumware called the Browser hijacks or the Cool Web Search Trojan.............when you find that your Internet explorer Browser home page is being changed to some Website you haven't set it to .there are chances it is the CWS Trojan
CWShredder is a good tool against it and Verson 2.1 releasd today press the little Update button now.
.............and about HijackThis ........it is a good dignostic tool but i wouldn't recommend it to everyone ..........until you know what you are looking for don't try to play with it it is dangerous too ..........you might delete some useful things with it .........not for non-tech people.
one good option is to Stop Using Internet Explorer altogether and you will see less and less Spyware and Adware in your scans

..............being the most widely used used Browser IE it is more attacked too ..................i would recommend Mozilla FireFox ..............it's Faster and still Hijack Free ......there is still no known browser hijack for it.
and the most Important thing to remember ...................with all these tools and they are
useless Unless you update them ..............They are as good as their reference files ....................so don't forget to update them once every week ..................or it's not even worth installing them .
So Update you Antivirus and AD-Aware or Spybot regularly ...............or they would be useless .....................always keep the latest verson alwys keep their reference Files updated ..............every minute a new virus is written .......and that makes them useless against the new ones if you don't update them .
