Lock symbol in the Mac Desktop area
Hello All
I have a mid 2012 MacBook pro on latest version of Mac OS. For the last few days, i have seen a "Lock symbol" on the desktop. It is totally new and appears in random location and is intermittent. When i scroll over the "lock symbol", a small pop up appears over it reading "secure connection". i have not clicked on it or anything.
I do not have a good sense about it. It feels that my Mac is hacked.
please advise on how to go ahead.
many thanks
