Questions about each
AdBlocker Ultimate
Does AdBlocker Ultimate have a free plan+
Yes. The model is listed as free, so browser blocking starts without charge. Paid app cover is separate for system wide blocking, so check which placement matches the devices used for daily browsing.
What are the limits of the free version+
Limits are described as Free browser extension; paid app for system-wide blocking. That means browser extension use is free, while full system wide blocking sits in the paid app. Readers who only need browser cover can stay free, while wider cover needs the paid tier.
Kaspersky
What does Kaspersky cover in a single subscription?+
A paid plan bundles antivirus with the extras Kaspersky lists as vpn, password manager and parental controls. That means the VPN, password manager and parental controls come in the same subscription, and parental controls add screen time, web filter and location tools such as screen time and location limits.
Is there a free Kaspersky antivirus?+
Yes, but the free build is limited. The free antivirus version covers Android only, and the premium VPN, identity protection and password manager require a paid plan. The password manager does have a free plan, and passkeys are supported there.
