Avast you say. Avast has a deal with google. When you download (or update from an older version) you will be asked if you want chrome.
it's on "yes" as default.
OK, great, mystery solved.
YouTube is owned by Google. If you have an old youtube account, you will automatically get a Google account with that youtube name.
when you want yo create a youtube account now, you will be transferred to the "create Gmail account" page.
so technically you are "with" google+ because you have a Gmail account, but you don't have to use it.
Anyways, this doesn't seem to be a problem anymore.
I linked to Alternate Google Chrome installer, because i thought you wanted to reinstall Chrome. i'll advice you to do so. IE suck big time.
You are a little hard to understand. i don't fully understand the problem you are having.
going though MSN and IE to get Google directly... whats that all about??
You hear clicks??? explain that to me.
