I have tried to remove the toolbar but it looks impossible. I have Windows 7. When clicking on "Change", the computer asks me to authorize Au_.exe in order to proceed, and of course i haven't done it. Then the process stops and a message comes out saying that the process requires admin authorization and so it will be aborted.
Instead, for all the other softwares installed on the computer there are both the options "Change" and "Remove" and so it's immediate to remove them. What's wrong? I would much appreciate your help.
Thanks!

So, I managed to get google back on.
The reason I hate Chatzum is that when your internet connection is down, it somehow makes things worse by not remembering the last URL you input. You then get a reject from the browser when you next try getting back on the internet. Chatzum creates a list of chatzum urls in the address box that is rejected by the server or internet. How stupid. Most other search engines don't have this problem . I would have reluctantly continued use of chatzum if there wasn't this glitch.
