Am on unlimited access on line but cannot access any website this evening

when am trying to go on a site i go to search then im receiving a msg ..your search returned no result iv been on line for the last week with no problems but this evenig its not letting me acces to any wbsite

may be a problem in your browser/and/or/internet security security settings? it may be that your setting for secure browsing may be too high/therefore blocking a lot of sites. Or it could be a new browser extension or add-on that changed the settings somewhere... if you've recently added either of these, disable them and see what happens. try re-booting your PC and browser too.
