No. Use Malwarebytes:

MalwareBytes for Mac:

If anything negative, its purchasing the full version - you're just as safe as you are with the free version. This is software that searches for malware/adware (malicious software). So, scan with it and then remove what is found. Once removed, uninstall MalwareBytes for Mac. Then restart the Mac. It is created by longtime users of these forums. So, that is why it is the only trustworthy and reliable way to go about securing your Mac, when it comes through use of software 

Downloads:

1. Malwarebytes Anti-Malware for Mac
2. Malwarebytes Uninstaller
