Every day, tens of thousands of people fall prey to virus attacks or fraud on the Internet. We have added special filters to the AdGuard app to protect you from malicious and phishing websites. | ||
Falling prey to phishing and malware remains a common issue. To enhance digital security, we’ve incorporated special filters in AdGuard products to shield you from malicious and phishing websites. To date, we’ve categorized over 15 million sites and built a database of 1.5 million websites known for phishing and malware. Using this database, AdGuard checks the websites you visit to protect you from online threats. | ||
|
||
So far, we have categorized more than 15 million sites, and our filters contain about 1.5 million phishing and malware sites. Just think about it: 10% of all known sites can be dangerous for you! Inexperienced users can easily become victims of fraudsters or hackers. We hope that using protection against malicious websites will help you avoid all hazards that you may encounter. | ||
::: note | ||
|
||
## How does a check work? | ||
We strictly do not collect or use any information about the websites you visit. | ||
|
||
The scope and methods of checks depend on the product you use. In our browser extensions, AdGuard inspects only the pages you visit. In AdGuard for Windows, Mac, or Android, we offer you the best possible protection by checking both the pages and all objects loaded on them. | ||
::: | ||
|
||
### AdGuard for Windows, Mac, and Android | ||
## How does AdGuard check websites? | ||
|
||
We use the protocol [Safe Browsing API version 2.2](https://code.google.com/p/google-safe-browsing/wiki/Protocolv2Spec) for our work with filters. This protocol allows us to keep your personal data absolutely safe. Our server knows nothing about the websites that you visit. We use hash prefixes for checks, not the opened URLs. | ||
Each time you visit a website, your local client exchanges information with our backend server in the form of hashes and hash prefixes. Based on this exchange, the local client determines whether or not the website is listed in the potentially dangerous websites database. There is a difference in the scope of this check for apps and extensions. | ||
|
||
The figure below provides a general understanding of how the Browsing security module works, using AdGuard for Windows as an example. | ||
### In apps | ||
|
||
![Functioning algorithm of Browsing security module](https://cdn.adtidy.org/public/Adguard/En/Articles/safebrowsing_adguard_for_windows.png) | ||
AdGuard provides the best possible protection by inspecting both the pages and all objects loaded on them. AdGuard checks URLs and domain names using hash prefixes, not the full URLs, so our servers retain no information about the websites you visit and your personal information is completely safe. Our servers respond to the app’s query with a list of all possible addresses that match the hash prefix. When a potential threat is detected based on hash matches, access to that website is immediately blocked. | ||
|
||
### AdGuard Browser Extension | ||
![DNS warning](https://cdn.adtidy.org/content/kb/ad_blocker/general/bs_diana.png) | ||
|
||
Browser extensions work differently, using the so-called [*Lookup API*](https://github.com/AdguardTeam/AdguardForAndroid/issues/162#issue-115487668) to check the pages you visit. Every time you visit any website, your local client exchanges information with our backend server in the form of hashes and hash prefixes. Based on this exchange, the local client determines whether or not the site is listed in the potentially dangerous sites database. For those interested in the process at a deeper level, the link above will be helpful. | ||
### In browser extensions | ||
|
||
We bring to your attention that we never get any information that could allow us to determine which websites you visit and use that data in any way. | ||
Our browser extensions can only check domain names, not full URLs. They are also unable to check subqueries. This means that if there are potentially malicious elements on the page, they will be loaded even if the page itself is from a safe domain. The extension won’t be able to protect against them. It's also important to note that the check performed is asynchronous, i.e. it happens at the same time as the page is loaded, so it’s possible that malware could be loaded as well. | ||
|
||
An approximate algorithm of the functioning of the Browsing security module is shown in the picture below. | ||
## Setting up phishing and malware protection in AdGuard products | ||
|
||
![Functioning algorithm of Browsing security module in AdGuard browser extensions.](https://cdn.adtidy.org/public/Adguard/En/Articles/safebrowsing_extension.png) | ||
- **For Windows**: Activate the *Browsing Security* module in the *Settings* menu | ||
|
||
## AdGuard filters | ||
![Browsing Security in Windows](https://cdn.adtidy.org/content/kb/ad_blocker/general/windows.png) | ||
|
||
We currently maintain two AdGuard filters. One protects against phishing and fraudulent websites. The other protects against malicious websites, visiting which may lead to a virus infection. | ||
- **For Mac**: Enable the *Security* module in *Preferences* | ||
|
||
### Phishing sites filter | ||
![Security in Mac](https://cdn.adtidy.org/content/kb/ad_blocker/general/bs_mac.png) | ||
|
||
*Phishing* is a type of online fraud aimed at gaining access to confidential data of users — username and password. If you are interested in this topic, we suggest that you read [this article at Wikipedia](http://en.wikipedia.org/wiki/Phishing). | ||
- **For Android**: Turn on *Browsing Security* in the *Protection* tab | ||
|
||
Apart from phishing sites, this filter also covers different fraudulent sites, including all kinds of scams, sales of nonexistent content, and such. | ||
![Browsing security in Android *mobile](https://cdn.adtidy.org/content/kb/ad_blocker/general/bs_android.png) | ||
|
||
### Malicious sites filter | ||
- **For iOS**: Although there’s no separate module, you can go to *Safari protection* → *Filters* → *Security* and enable the available filters. Additionally, enable *DNS protection* and select one of the AdGuard DNS servers | ||
|
||
This filter contains links to pages that could execute malicious code, leading to potential leaks, data loss, or damage to a user’s device. Code execution can be authorized (for example, when downloading and running the executable file) or unauthorized (for example, when being attacked with spyware). | ||
![Security in iOS *mobile](https://cdn.adtidy.org/content/kb/ad_blocker/general/bs_ios.jpg) | ||
|
||
## How do we add new addresses to our filters? | ||
- **For Browser extensions**: Enable *Phishing and malware protection* in the *Settings* tab. For enhanced protection, go to *Filters* → *Security* and activate available filters | ||
|
||
Most of the work is automated, so you can be sure that new malware and phishing addresses are added to our database as quickly as possible. | ||
![Phishing and malware protection](https://cdn.adtidy.org/content/kb/ad_blocker/general/extension_protection.png) | ||
|
||
### AdGuard Browsing security Community | ||
- **For Private AdGuard DNS:** Enable malware protection in *Server settings* under *Security* | ||
|
||
An important tool for maintaining the highest level of filtering is the *AdGuard Browsing security Community*. Any user of our products — be it AdGuard for Windows or our browser extension — can become a member of the community and help us in the making of AdGuard filters. | ||
![Security in DNS](https://cdn.adtidy.org/content/kb/ad_blocker/general/bs_dns.png) | ||
|
||
In the image below, you can see an algorithm of how Browsing security Community works: | ||
## What we block | ||
|
||
![The way AdGuard Browsing security Community works](https://cdn.adtidy.org/public/Adguard/En/Articles/browsing_security_community.png) | ||
We maintain two primary filters: one that protects against phishing and fraudulent websites that attempt to steal user credentials, and another that blocks access to websites known to distribute malware, which could lead to data loss, information leaks, or damage to your device. These filters also protect you from websites with various scams and fraudulent schemes. For more detailed information, refer to this [Wikipedia article](https://en.wikipedia.org/wiki/Phishing). | ||
|
||
### Want to help? | ||
## Maintaining our filters | ||
|
||
We will gladly accept any help! If you want to send us a complaint about a phishing or malware site, you can do it via technical support at **[email protected]**. | ||
AdGuard maintains an extensive database of phishing and malware websites, and it’s updated regularly and automatically as new threats are discovered. We collect information from a variety of reliable, high-quality sources, both public and from other companies, and aggregate it into a common database of dangerous sites. | ||
|
||
### False-positive responses | ||
We automatically analyze complaints about suspicious sites and spend a great deal of time keeping the database up-to-date, cleaning up false positives, and implementing mechanisms to prevent them in the future. | ||
|
||
Occasionally, some non-malicious websites get added to AdGuard's filters. We do our best to reduce the percentage of false positives, but they still occur. If you come across this behavior from AdGuard, please send us a complaint about the false-positive alarm. You can submit such complaints via our technical support at **[email protected]**. | ||
