AdFender review
A paid Windows proxy filter with broad blocking controls and custom rules.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
AdFender is Windows content-filtering software that operates as a local HTTP(S) proxy. It is designed for users who want to block banner, video, and pop-up ads alongside online trackers, malvertisements, and tracking or profiling cookies. Filtering can apply to major browsers and supported custom applications, while site exclusions and temporary filtering controls provide ways to adjust how protection operates.
AdFender Professional is priced at $15.95 per PC per year with annual billing. The plan includes ad blocking, tracker blocking, malvertisement protection, cookie removal, and automatic filter updates. A 14-day trial is available, but there is no free version. The license covers one PC and does not renew automatically, making the cost and coverage straightforward for a single Windows desktop but less suitable for users seeking multi-device access or an ongoing free option.
Its main distinction is the breadth of filtering control within a desktop proxy. In addition to HTTPS filtering, AdFender supports custom filter rules, imported third-party rules, custom application filtering, and temporary disabling of filtering. Those controls should appeal to Windows users who want more configuration than basic browser ad blocking. Users who need a Windows-focused blocker with proxy-level filtering and custom lists should consider AdFender Professional. Users seeking broader platform coverage, a free plan, or a license for more than one PC should choose an alternative.
