Can't get rid of my start home page by incredimail

Which browser are you using ?

With out knowing what you are using to access the home page cannot give proper information.
Chrome, Sarifi, MAC, IE??

Just go to tools or setting pannel of your browser and by opening it dispalys a window that contains many tabs at the header(top of the page) you see address bar in setting panel named with home page.. just replace the old one by you desired new one and save settings

Incredimail is very close to being malware - I would suggest to any of my tech support clients to uninstall it and do a thorouigh cleaning (Registry, etc) of their PC afterwards.
