I want to secure my Mac PC, anybody suggest me best Mac malware scanner.
You can choose from these three:
Comodo Antivirus for Mac has user-friendly interface, uses quarantine system to isolate suspicious files and has flexible virus scanning that runs on a schedule convenient for you --- all for free.
Kaspersky Internet Security for Mac provides extra security features, including parental controls and options to lock down your webcam and stop websites from tracking your browsing activity, if you are willing to pay.
Bitdefender Antivirus for Mac has modern, streamlined interface that places on-demand scans front and center. Came second from Kaspersky since system-impact scores didn't match the flawless marks by Kaspersky.
A good anti malware for mac is very important. I think TotalAV as is the best malware scanner. It removes all viruses, malware, adware & Spyware, you can even get a 100% Free Antivirus Software.
