you may want to download malwarebytes and/or super anti spyware. (both can be downloaded at download.com) Secondly you may want uninstall your antivirus and reinstall to make sure its all placed back together correctly.
When have a dozen of our pcs got that greeting card virus, first I noticed that mcshield was disabled. When I rebooted the pcs, the service was removed. I had to reinstall virusscan (this happened on both 8.5 and 8.7.) You can do add/remove and then reinstall from original product.
I scan my pcs to see if mcshield or framework service is disabled (I use perl code.)
