A couple days ago, I tried to download Google Chrome. I let the download install while I went to work. When I came home, it was stuck on the second step. I stopped it.
I didn't know it at the time, but Firefox was also trying to download an update. I stopped that too. I tried to access both my Yahoo and Hotmail addresses, and it would kick me back to the sign-in page every time I tried to do anything (read mail, reply, delete mail, empty Spam, etc.) The same thing happened when I tried to access my Hotmail, but even worse.
I deleted all cookies from both browsers and rebooted. Still misbehaving. A system restore brought temporary relief, but the problem was back within 24 hours.
I have removed and reinstalled Firefox. When I removed it, I told it to take away everything, as if I'd never install it again. I did not import my Favorites/bookmarks from IE either.
IE is acting just as badly as Firefox for me. I did a Bit Defender scan, and no problems were detected. Is there anything else I can do, short of reformatting my computer? Thank you for any help you can provide me.
