I have somehow ended up with an apparent virus/trojan thing called MyStart Incredibar. This takes over the browser and substitutes Incredibar for your home page.
Uninstalled it using Revo Uninstaller but that did not get rid of the problem. I have run Malwarebytes, my ESET NOD32, SpyBot etc and although some of these came up with a few bits to be cleaned, it didn't fix the problem.
I have also googled quite extensively looking for a fix and although there's a lot of traffic on the subject, nothing I can see that seems to be legit or make sense.
Does anyone know anything about this or can suggest what I should do? Thanks.
