Download and install
Adguard is an install-and-forget program. Installation process will take no longer than 3 minutes. After that, you just surf the internet as you usually do. Adguard protects your computer and doesn't make you change your web habits.

Filtering
After running Adguard, the program immediately starts to filter all your Internet bandwidth quietly and very quickly.

Protection and blocking
When processing a web page, Adguard does several things at once:
1 Removes ads and online tracking code directly from the page.
2 Checks a page against our database of phishing and malicious sites.
3 Checks the reputation of the website and informs you about it, if necessary.

Comfort and safety
You will be amazed how much more comfortable and safer the Internet will be after you install Adguard.

Adguard for Windows 5.10
Short list of important changes: greatly reduced memory usage, we introduced convenient addition of new ad filters, integration with WoT is now a separate extension, added support for new browsers, fixed conflicts with popular programs and defects in the processing of requests and more.

Memory usage reduction
We have significantly optimized memory usage in 5.10. Now, even if you use an old computer or a weak netbook, Adguard will work silently in a background without slowing down your device. We compared memory footprint with the one of the preceding version. And we must say 5.10 showed a result several times lower.

More ad filters
In addition, Adguard has became an even more comprehensive program. Now users can install any ad filters. What does it mean? In addition to the filters that are already installed in Adguard by default, you can add third-party ones, such as a list of filters that allow Adguard to block ads in different segments of the Internet - websites in different languages, in particular. All of this can be done directly in the program, simply by selecting a filter you want and clicking on the "Add selected" button.

Displaying the possible danger
Integration with Web of Trust is now brought out in the separate extension, which can be disabled. Also a warning when visiting a suspicious website has changed. With the help of WoT, our Adguard is able to notify you instantly about the reputation of websites and show the reasons for which the site is considered to be suspicious. "Categories of suspicion" can be, in particular: scam, potentially illegal, misleading claims or unethical, poor customer experience, privacy risks and others.

Other changes in version 5.10:
Added support for CSS injection rules. It gives us more flexible options for high-quality elements blocking.
Ability to edit the source code of userscripts. Now you can customize any script you like, you can find more about what it is and how to install it here.
Updates are checked only for the enabled userscripts.Thus we update only those scripts that you actually use. Why spend the extra traffic?
Extensions that do not use external resources are returned to the "default." Now you have the opportunity to reset the extensions and return websites to their original state.
Added a configuration of exceptions for secure (HTTPS) sites filtering. Adding https websites to exceptions in order for Adguard to not filter it, used to be impossible.
Increased time of filter updates up to 12 hours. Yeah, longer but of better quality.
Speeded up the work of extensions (including Youtube Center). Userscripts do not slow down websites now.

Fixed conflicts with Visual Studio, Tor Browser, Keepass.
