How can I remove a virus on safari?
when I try to enter safari, I get a message that I may have picked up a virus and I should call a particular telephone number. I do not recognize the name of the company (it is not apple). Is there anything I can do? I have tried to trash the safari application and I am told that OS X requires safari. I installed Google Chrome so that I am able to use that as my search engine. Can anyone help?
MacBook Air, OS X Mavericks (10.9.5)
