I think my iMac is infected and could really use some help
I recently purchased an iMac for the 1st time and am having many pop ups, survey requests and emails sent from my account to people in my address book. I used the chat help that came up on the Apple support which was a 3rd party who did a diagnostic check on my computer. They told me my computer was infected and wanted to charge me $159 to fix it. I could really use some suggestions. I have heard that apple computers don't get infected but it appears mine did.
