System-level ad blocking
AdBlocker Ultimate for Windows works at the system level, not inside a single browser. This means it can block ads in all applications on your PC — browsers, email clients, media players, games, and messaging apps — overcoming the limitations of browser extensions.
Works across multiple applications
Protection is not limited to your browser. Any application on your PC that loads external content can benefit from AdBlocker Ultimate's filtering.
Network filtering
Blocks connections to ad servers at the network level before they are able to load, resulting in faster performance and lower data usage.
DNS protection
Blocks known malicious and advertising domains at the DNS level, providing an additional layer of protection before any connection is even established.
HTTPS filtering
Filters encrypted HTTPS traffic so that ads on secure websites — including YouTube and Facebook — can be blocked. This requires a locally trusted certificate, which AdBlocker Ultimate installs during setup.
Tracker and privacy protection
Blocks online trackers that monitor your browsing behaviour and build profiles about you without your consent.
Crypto miner protection
Stops scripts that attempt to use your device's processing power for cryptocurrency mining without your knowledge.
Malware and phishing protection
Blocks connections to domains known to distribute malware or conduct phishing attacks, keeping your data and device safer.
Per-application control
You can choose which applications are filtered and which are excluded — useful for banking apps or other security-sensitive software that may be incompatible with HTTPS inspection.
