Approximately one month ago I began to experience (for the first time ever) multiple popups and then random opening of tabs while using the internet. I noticed something I'd never seen before: the name "Trovi" in the address bar. "Trovi" was taking over my computer and blocking my usual start up tabs. I could still use the internet, but the popups and the tab openings seemed to multiply with each search. I tried to remove Trovi by using adwcleaner, but that created a new situation with the use of the internet. I can no longer access the internet. I receive messages stating that the proxy server isn't responding and then the website is online but isn't responding to connection attempts. Your help is sure appreciated.
