First off, you need real time protection activated in paid subscription antivirus and antispyware and a personal firewall..... Real time protection (heuristics) blocks installations.

Microsoft AntiSpyware is now Windows Defender
[working-freeware from Microsoft]
http://www.microsoft.com/athome/security/spyware/software/default.mspx
Windows Defender is a free program that helps protect your computer against pop-ups, slow performance, and security threats caused by spyware and other unwanted software. It features Real-Time Protection, a monitoring system that recommends actions against spyware when it's detected, and a new streamlined interface that minimizes interruptions and helps you stay productive.
Windows Defender is very good but the not the best rated in paid programs like Trend Micro Antispyware, Webroot Spysweeper, Counterspy. The most important things are that you need a personal firewall (NOT XP firewall) and real time protection shields that will block further communications and even more installations from what is sitting there right now. Back door threats with trojans and rootkits on the machine can continually install more and more and as well, you can get caught up into a malware botnet (google it) or slang - 'zombie networks'. So cut off severe threat communications and then clean the pc.

a-squared (a-squared) is a complementary product to antivirus software and desktop firewalls on MS Windows computers. Antivirus software specializes in detecting classic viruses. Many available products have weaknesses in detecting other malicious software (Malware) like Trojans, Dialers, Worms and Spyware (Adware). a-squared fills the gap that malware writers exploit. Automatic updates: In a-squared Free the updater must be run manually. The auto-update feature of a-squared Personal checks hourly for new available updates and installs them automatically. a-squared Free is freeware!
Without paid subscription security software including a firewall, antivirus, and antispyware - you will never get out of a help group. The threats are more and more and more sophisticated. Of course the worm is about worst which can delete file after file and directory after directory and eventually the Windows OS itself.
PS.... Spybot Search And Destroy was a first attempt at antispyware years and years ago. It is what they call today "crapware" because in al independent lab tests it has continually rated as one of the worst on the world web. You are asking for free help and that's what you get at least 50 percent of the time - uninformed security solutions from uninformed consumers / pc users. These are newbies and even cyber criminlas offering piss-poor solutions to give you a false sense of security making you their mark. Watch out !
