That's what I thought, that these are left-overs of the virus removal. I'm willing to instruct her through a look at the registry. If these add-on fragments are as simple as my Google add-on, she can easily be rid of them. Feel free to stop me if you've got a bleepingcomputer guy at hand.

MariaChunle -- the steps may appear daunting, but they are not. You do need to be careful though as editing the registry incorrectly can cause the PC to become unstable or even unusable -- rare, but it can happen. In that case, you're looking at a recovery to get back into Windows.
