I have this problem too

I think I may have solved this problem, I did try the above solutions but unfortunately they didn't work. However I downloaded Firefox 7 again, uninstalled my the Firefox I had and installed it again, so far so good. I was really surprised that this problem occured and I didn't like being redirected to another home page. I like Firefox and up until this happened I have never had any problems with Firefox.

I have the same problem. But it is isn`t a problem with firefox. the problem is in windows. and i`m still searching for the problem there

Thank you, I thought it was just me. I thought that because I also cleaned out my system and took it back to the basics. I wasn't sure if it was to do with google/gmail. My email account is a gmail account, I have been trying to find another one for a while now but they all seem to have adverts attatched to them or some other niggle I don't like.

1. Kill guardServiceCh.exe in Task Manager (I used Auslogics Task Manager). 2. Delete (with pressed Shift) the folder "Program Files\Google\Common\Guard". 3. Reboot your comp.

Then what exactly do you want to achieve?

Can you give an example?

its worked for me so far cheers mate :)
