Fish on, fish on...... ok, I've taken the bait. If the OP is using IE to browse, my first suggestion would be to upload Chrome and then dump IE and all it's components from their computer. In my experience after doing so I felt more comfortable walking about without my foil hat, at least indoors.
OK it is "www.ingunowners.com" OH by the way this site.
I have to type in the address to view it.
Just now I scanned my bookmarks. Not there.
I use "firefox". I never had a problem before.
I would about a month ago. I had INGO as the third bookmark.
Then they did an update.
As I scanned the bookmark page. I seen "bookmark search".
never seen that before. I found INGO there.
It presented INGO.
Which I opened.
Another thing, I am never signed off of INGO.
I always click "log off".
The other day when I opened INGO i noticed I was already signed on.
Same today.
OK, less snark this time. I'll put on my IT guy hat.
Your bookmarks are under your exclusive control. Your ISP cannot control what your bookmarks are/arent unless you have allowed them to install software on your PC. (not likely, but not out of the question as Comcast has a history of telling new customers they must install software during the setup process. And some techs also ran it for you if it was a supervised install)
Odds are your browser upgrade went squirrely and deleted some content. Re-add the bookmarks and you will be fine.
Now if you get "page not found" errors or "content blocked" errors, THEN you have a comcast problem.
Sounds like your PC and/or browser has issues. What antivirus software do you use?
