Avast Online Security & Privacy is a free browser extension that lets you control who has access to your private data, and warns you about malicious websites and phishing scams.

Block tracking systems

Most websites use tracking systems to monitor visitor behavior, which allows them to obtain statistics and other data for marketing purposes. The Anti-tracking feature in Avast Online Security & Privacy allows you to see which tracking systems are used by the websites you visit and stop them from tracking you.

When you visit a website that uses tracking systems, the number of trackers is visible on the Avast Online Security & Privacy icon to the right of your address bar.

To manage website tracking systems:

1. Click the Avast Online Security & Privacy icon to the right of your address bar.
2. Click the Anti-tracking icon in the left panel. The Anti-tracking screen lists the most common types of tracking system:
   • Social networks
   • Ad Tracking
   • Web Analytics
   Alternative types of tracking systems are in the Others category.
3. To block all types of tracking systems on every website you visit, click the red (OFF) slider next to Prevent tracking on all websites so that it changes to green (ON).
   
   Alternatively, use the slider next to an individual tracking system category to enable or disable Anti-tracking for this category only. Your preferences apply for every website you visit.

Avast Online Security & Privacy is now blocking the selected tracking systems.

Opt out from advertisers

Online advertisers are companies that collect information about you by tracking your online activity. This information can be used to create a profile of you as an individual, and target you with ads that appear to match your interests and behavior.

The Ads opt out feature in Avast Online Security & Privacy lets you send opt-out requests to online advertisers. After receiving your opt-out requests, the online advertisers are legally obligated to stop collecting and selling your personal information.

To send your first opt-out requests:

1. Click the Avast Online Security & Privacy icon to the right of your address bar.
2. Click the Ads opt out icon in the left panel.
   
   The Ads opt out screen lists each of the online advertisers that Avast Online Security & Privacy can contact on your behalf.
3. Click Opt out to send opt-out requests to all of the listed online advertisers.
   
   Optionally untick the box next to an individual online advertiser if you do not want to send an opt-out request to this company.

Avast Online Security & Privacy sends opt-out requests to each of the listed online advertisers.

Avast Online Security & Privacy continuously scans for new online advertisers. Ensure that the slider next to Opt out from all new advertisers is green (ON) if you want Avast Online Security & Privacy to automatically send opt-out requests to new online advertisers.

Optimize privacy settings

The Privacy Advisor feature in Avast Online Security & Privacy allows you to access and use our privacy guides. Privacy guides provide step-by-step instructions on how to adjust the privacy settings of your major online accounts to reduce the amount of personal information you share.

To improve the privacy of your online accounts:

1. Click the Avast Online Security & Privacy icon to the right of your address bar.
2. Click the Privacy Advisor icon in the left panel.
3. In the Guides to explore tab, check the available privacy guides that you have not yet completed. The preview for each guide shows the following:
   • The online account that the guide relates to
   • A summary of what you can achieve by completing the guide
   • An estimate for how long the guide takes to complete
   
4. Click the privacy guide that you want to complete. Settings for the relevant online account open automatically in a new tab.
5. Follow the on-screen instructions that appear in the Avast Online Security & Privacy dialog boxes to complete the privacy guide.

After you complete a privacy guide, it appears under the Completed guides tab on the main Privacy Advisor screen.
