i received this same error message, and against my inner voice of reasoning, called the number. a guy with a heavy indian accent answered as tech support, i asked, "who did I call?" and he only responded with "tech support". but....i went on with the call, explaining that i received this pop-up error mesg. he said all computers come pre-installed with this error warning. stupid me. i continued with the call. even though that voice was telling me not to. i asked, "what's this going to cost me?" he replied "no, no, this call will not cost you anything", he had me download something that allowed him to take control over my macbook. he showed me where my "filevault" is turned off, and that there was a foreign address in my system dialog, and that my network had been hacked. when he said he was going to connect me to "cisco systems" or something like that, so they could remove a foreign address on my computer, and that it was a paid program, i said that i could not afford to buy anything that day. then he "negotiated" a different price twice, and i said, "NO. i cannot buy anything today. " then he said, "what is the problem? do you not have access to the card number?" that's when i said, "i'm ending this call"
so should I worry that he installed something on my mac? what about that foreign address? and what about my filevault? i have webroot secure anywhere on my mac. i ran a scan before i called that number and it didn't show anything wrong, and then again after i called that number. does not show any virus, or malware or spyware. but how did that error msg get there?
i'm sorry, i'm not real computer literate, so if i sound totally stupid with my questions, please forgive me.
is there anything i should do?
thank you all...
