see if you can "restore" your computer to a time before you were infected.
also check out this website:
http://www.spyware-techie.com/packedmorphined-removal-guide/
i cant vouch for the site or info, but it came up with a google search of your virus.
i would also run adaware and spybot a few times as well.
1) adaware -
http://www.lavasoftusa.com/software/adaware/
get it from this site. there is another "adaware" program out there that may INSTALL spyware. that program is trying to trick people into installing it, instead of the "good one."
adaware is free, but you can buy the addon that constantly scans your computer for ad/spyware.
2) spybot -
http://www.safer-networking.org/en/index.html
also a good one. i have BOTH on my computer and run them once a week or so. they appear to scan for many of the same things, but there are somethings one gets that the other does not.
i have never had any problems with either of these programs.
make sure you have an anti-virus program AND THAT YOU UPDATE THE DATA FILE REGULARLY.
last, you might want to consider changing browsers and run firefox. this browser does not have all the problems that ms explorer does.
