My Firefox search was taken over by utorrent. I (dozily) uninstalled utorrent with add/remove programs which only removes the Swastika and leaves the whole Nazi party intact.
So having removed it and removed any add-ons from Firefox I was unhappy to find it still persisted.
Then all my search boxes were taken over by Conduit.Com which gives limited and partner based results to any search....
....such as "remove Conduit.Com" takes you to a page that has a McAfee result where they are quoted as saying that Conduit is not malware and does NOT need to be removed.. there are McAfee logos but the page is provided by Conduit.Com.
I'm using Revo Uninstaller to remove everything. I now have to install utorrent again so it can be thoroughly uninstalled by Revo.
Apparently bittorrent behaves in the same way. Maybe they're selling out as a final straw clutch before going under.
....and both are available from CNET . so another trust broken.
After Revo does the usual Microsoft uninstall it then proceeds to root out up to 170 files that are left behind (Firefox example) most of which are in the registry. Even uninstalling an innocuous app leaves 22 files behind.
Oh well, after I've cleaned it up I'll install Zorin Linux alongside Windows 7 and only use 7 for games. Uninstall from Linux leaves nothing behind. I have to say that Chrome allowed me to remove the add-ons completely and they haven't returned to Chrome. Firefox is okay at present after two deep uninstalls. IE9 doesn't even know the add-ons are there and remains unuseable (not much change there then).
NOTE TO SELF..only use torrents in Linux and you can no longer trust CNET.
