If you own an MacBook Air, and it requires service for any other issue, you still have access to all available service options, but you will be responsible for the cost of service, including parts, labor, shipping (if any), and applicable taxes. AppleCare or your local AASP or Apple retail store representative will provide you with an estimate of service costs before receiving your authorization to perform service.
The first time you install Malwarebytes, you’re given a free 14-day trial of the premium edition, which includes preventative tools like real-time scanning and specific protection from ransomware. After two weeks, it automatically reverts to the basic free version that will detect and clean up malware infections only when you run a scan. It is important to note that Malwarebytes will run alongside antivirus software without conflicts.
