Locked Safari
Hi everyone. Safaris locked up on me. A window has popped up saying, "http://www.404-errors.info Security Error." Underneath that it says, "Call helpline 1-877-899-1824." On searching for that # in Firefox I get very crazy locations, such as "All Services Electric, Cedar Lake..." Tried some of fixes that didn't work, including resetting the auto time. Any ideas?
MacBook Pro, OS X Yosemite version 10.10.1
