This depends on the number of PCs you want to protect.
The only difference between Systweak’s packages is the number of devices they cover. If you’re only looking to protect one PC, the Individual plan is right for you. If you want coverage for 5 or 10 devices, then you should check out the Multi-Device and Family packages, respectively.
I find it pretty irritating that Systweak charges significantly more for its higher-tier packages without providing additional protections. Antiviruses like Norton and McAfee offer valuable extras like identity theft protection, unlimited VPN usage, and other tools with their premium packages.
