Never had a problem with system restore, so long as you don`t go too far back. A month or two should be fine to check if it did it back then. Can undo it afterwards if it`s uninstalled a lot of programs. ( put any files you don`t want touching into My Documents ).

But probably best solution has already been suggested, ditch IE and get something else. I`ve never used Chrome, there was a thread on here not long ago where someone was having problems with it. There`s also Safari, Firefox etc.
