So did i kill this virus/trojan/worm/adware/malware :S?

i downloaded this video object divx and it turned out to be a virus, so i dled a program that would remove this virus because whenever i tried to delete the infected files it wont allow me and windows just kept on popping up threat alert threat alert and leading me to their affiliate anti virus companies

software site

so i went in ctrl alt delete and ended all processes tree of the infected programs and then tried using the program again, while during the proccess it said access denied when i rebooted computer, the registry told me the virus was deleted and when i checked the former location of the virus the folder was gone and there is no longer the virus application running in processes and the threat alert was gone and computer doesnt seem to slow down for no reason

so did i kill it?

and i think it downloaded alot of spyware and adware on to my computer before i killed it is there any good free removal software for this?

Here are a couple:

Ad-Aware SE Personal

Spybot - Search & Destroy 1.4

They are both free by the way.

After I rid a computer of a virus I take it offline,run scans from adaware,spybot,hijackthis.Then I run a duplicate and empty file searcher and clean that up manually.Then I run a registery cleaner then defrag the hard drive.Scan the boot sector and total machine again.Then and only then am I still 'unsure'if a virus is gone.
I'm being serious.One never knows if a cpu is clean.As far as I am concerned ,and in my opinion ,if you can get a virus then you may still have one unfound ,or a trojan waiting for a phone home command or a worm waiting for a set date etc...
Backup your data , cross your fingers and remember that it is just a machine with parts that you maintain.It will perform better with more maintanance and preventitive maintanance but no one online is ever truly safe from the junk thats out there.
Good luck and keep your chin up because if it can happen to you it can happen to us all.
