Avast Free Antivirus 18.6.2349
Windows 7 Professional
Everything was working fine yesterday and for years.
Then today, I can no longer get dropbox to connect. I cannot visit websites either unless I'm using Chrome and the site is a Google site (e.g., Google searches, Google+). I get a "This site can’t be reached" message in Chrome or "The connection has timed out" in Firefox for all other sites.
When I turn off Web Shield in Avast, everything works fine.
I have tried restarting. I have tried Avast's repair function and then restarting. Neither have worked.
Can anyone help?
Thanks!
