Tried to get streaming news on internet and got a virus. Symptom is both Internet Explorer and Chrome cannot access the internet. Can use Waterfox and access internet OK.
Sometimes get message "Unable to connect to the Internet. Google Chrome can't display the webpage because your computer isn't connected to the Internet." Sometimes get message "This webpage is not available." and it times out. Proxy server box is not checked.
Ran Malwarebytes and found nothing, but Malwarebytes cannot update (can’t access internet.)
Ran Kaspersky Virus Removal Tool and found nothing.
Tried to run Spybot but it can't update (can't access internet) and won't run system scan.
Has anyone identified this problem? How can I fix it?
