|I don't think they are too serious, more of a nuisance and at least one of them might give you unwanted adverts. They both appear in Google.|
Try the simple things first:
If they appear in Control Panel > Add-Remove, uninstall them from there.
Also look in IE > Tools > Manage add-ons. Set to show all add-ons (dropdown near the bottom). If either or both appear there, uninstall them - or at least disable them.
We can take it from there if necessary.
Always pop back and let us know the outcome - thanks
