Pros and cons
AdBlocker Ultimate
Pros
- Wide coverage across Windows, macOS and Android for desktop, mobile and browser use
- DNS privacy options include doh, dot and dnscrypt on supported Android builds
- Focused ad blocking scope via ad blocker that keeps setup clear
Cons
- Closed review path, as open source is no, which limits outside code checks
- Support runs on email and help centre only, which limits direct contact routes
Kaspersky
Pros
- Kaspersky Premium bundles the VPN, password manager and parental controls (vpn, password manager and parental controls) in one subscription a family plan can share
- Device and platform coverage is generous: 10 devices at once, with apps for Windows, macOS and Android on desktop and mobile
- Streaming and travel are stated features, with Netflix, Amazon Prime Video and Disney+ supported and kill switch and split tunnelling built in as standard
Cons
- Support runs on help centre and community only, so quick answers go through documentation or the community rather than live chat
- The protocol list is WireGuard, so readers who want a wider choice of protocols have less room to compare
- The free version that Kaspersky lists sits with antivirus rather than a free VPN, so VPN features start on a paid subscription
Who each suits
AdBlocker Ultimate
Who it suits
- Everyday browser readers who want free blocking before paying for wider cover
- Multi browser households that want the same ad blocker across desktop and mobile
Who should look elsewhere
- Choose DeleteMe for data broker removal rather than browser ad blocking
- Choose addy.io for masked mail handling rather than page level ad blocking
Kaspersky
Who it suits
- Households that already pay for Kaspersky security software and want the VPN folded into the same subscription rather than bought separately
- Travellers who want one app for secure connections on Windows, macOS and Android across phones and desktops while abroad
- Families sharing one account, since the family plan passes the same subscription across to other members in the household
Who should look elsewhere
- AVG, if server spread matters most, since its coverage starts at from 100 countries, further than Kaspersky reaches
- Namecheap, if you want the widest server list, since it lists from 100 countries or more across its network
- ESET Brasil, if device counts drive the choice, since its plans scale from 3 to 25 devices under one plan

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 Premium include besides the VPN?+
One Kaspersky Premium subscription covers vpn, password manager and parental controls, and the family plan lets the same subscription be shared with family members through one account. That bundle is the main reason to look here rather than a standalone VPN.
How many devices can one Kaspersky subscription cover?+
The plan covers 10 devices at once, which suits a couple or a shared family without straining. Server reach runs to 93 countries, a wider spread than the median VPN listed on the site.
