System Mechanic Ultimate Defense is the iolo package that offers the most value. On top of the malware scanner and real-time protection, it comes with excellent device optimization tools, a reliable password manager, and identity protection. It can only be purchased as an annual plan, but if you consider the per-month cost, it’s an affordable antivirus.
That said, System Mechanic Pro isn’t too bad. It lacks the password manager and certain privacy protection tools, but you still get the malware scanner and optimization tools.
Regardless of the plan you choose, you get a 30-day money-back guarantee.
