Can't connect to certain sites
I'm having a problem that seems to be getting worse. I get one of two things happening but both are related:
1) In any browser, when going to Google it tells me that the server can't be found.
2) In any browser, I get an error for Google, Gmail and Apple that the browser has detected a virus and should it proceed. When I choose proceed, it tells me access denied.
It fixes itself when I restart. But the problem comes back. Lately, it's started happening multiple times per day.
Any suggestions?
