Few days back I tried a screensaver( marine free) that comes bundeled with new.dot net and it changes ur home page. I used spyware blaster to protect my IE home page with all updates of spyware blaster and max settings. I tried it at least twice and each time my home page was changed. I wonder why it happened so( Windows Defender did informed me the change and it was successful in restoring it)? If anybody wants to try, PM me and I will give the download link of this screen saver exe.
