How I got rid of Gamevance

So here goes. Gamevance is an old-fashioned install-once, make-you-cry-forever virus that sits in Firefox as an add-on. So how to get rid of it?

I googled a few answers, but they were apparently for the old version. I even installed a tool for malware removal, but that didn't help.

I found and deleted the Gamevance folder with program files. No good. I scanned the registry and removed things pertaining to gamevance and its short name gvtl. No good. It was back again. I disabled, uninstalled, crashed (killed) the browser on purpose, but nothing would stop firefox from reinstalling it again without my permission.


A little more perseverance paid off. I went to this location:
C:\Documents and Settings\<my-logon>\Application Data\Mozilla\Extensions\
and there I found the extension {ec8030f7-c20a-464f-9b0e-13a3a9e97384}. This belongs to gamevance. I removed this folder, and voila! it's gone
