Antivirus products are designed to protect your device from security threats, such as viruses, trojans, and malware, but will not prevent online tracking. VPN products are designed to hide your location by encrypting your connection. However, when you use VPN alone, trackers can still identify you based on your device, browser, and online behavior. Unlike antivirus and VPN products, Avast AntiTrack is designed to prevent third parties and advertisers from tracking your online activity.
Avast AntiTrack is not an ad blocker and you will probably still see ads on some of your favorite websites after installing the application. However, Avast AntiTrack prevents trackers from gathering information about your online behavior and stops you from seeing targeted ads (for example, an ad for a product you recently viewed).
Online tracking is the process of gathering information about you through sophisticated analytics embedded on websites. Information gained via online tracking is used to create your unique online profile (or digital fingerprint), which allows advertisers to identify you online. This can affect you in several ways:
Avast AntiTrack uses a local VPN connection that allows the app to protect your privacy. When tracking protection is enabled, a lock icon appears at the top of your device screen and the Privacy status screen in Avast AntiTrack displays the message Secured from trackers.
When you visit a website, you usually provide data related to your device configuration, browser, and online behavior. This is continuously stored and builds as you continue to interact with websites. Almost every website collects user data via the same types of advertising networks, which means that all your online activity is tracked and added to your own unique online profile. As you repeatedly visit your favorite websites, access your online accounts, shop online, and fill various forms, your online profile behaves like a "digital fingerprint", which you leave everywhere you go on the web.
Your digital fingerprint is not connected to your actual identity, but it can be used to create an accurate profile of you as an individual. Online tracking techniques study your interests, age, religion, medical issues, income, expenses, shopping habits, and other highly personal information. While this helps sellers personalize their ads, it can also represent a violation of your privacy. Avast AntiTrack protects your online identity by continuously changing your digital fingerprint.
Cookies are files that websites, trackers, and third parties leave on your browser that allow them to view your online activity. Targeted ads, which are ads that appear to match your online activity, are a direct result of cookies on your browser. Cookies may also cause websites to display higher prices for products that you have been researching online, including flight tickets. To prevent targeted ads and to protect your privacy online, it's important to clear your cookies regularly.
Browser data is information that is often stored in your browser when you interact with websites. Browser data allows anybody else who uses your device to view your search history, and see which websites you have visited. Additionally, browser data allows websites to automatically fill forms and keep you logged into your accounts after you close a browsing session. Although this can be convenient, it also puts your privacy at risk and may allow third parties to access your private data. Avast AntiTrack makes it easy to remove browser data. You are always prompted to select which types of data you would like to remove before clearing browser data.

The graphs at the top of the screen show fluctuations in blocked tracking attempts over the past 6 months and the past week. Hover your cursor over the red dot above a specific month or day to see the exact number of blocked tracking attempts.
On the Avast AntiTrack dashboard, you can view the most recent attempts to track you in the Latest Tracking Activity box. For each attempt, you can see the Tracking Source and the website that you were tracked from. For a more extensive view of your tracking history, select Reports in the left panel, then click the Tracking History tab.
If Google Chrome is installed on your PC, you are prompted to manually install the Avast AntiTrack browser extension in Google Chrome after installing and activating Avast AntiTrack. For all other browsers, browser protection is automatically enabled.
Your Windows operating system has many privacy related settings that Avast AntiTrack can optimize and monitor for increased privacy. By enabling the recommended system privacy settings in Avast AntiTrack you can:
Web researcher David Eade found and reported CVE-2020-8987 to Avast: this is a trio of blunders that, when combined, can be exploited by a snooper to silently intercept and tamper with an AntiTrack user's connections to even the most heavily secured websites.
This is because when using AntiTrack, your web connections are routed through the proxy software so that it can strip out tracking cookies and similar stuff, enhancing your privacy. However, when AntiTack connects to websites on your behalf, it does not verify it's actually talking to the legit sites. Thus, a miscreant-in-the-middle, between AntiTrack and the website you wish to visit, can redirect your webpage requests to a malicious server that masquerades as the real deal, and harvest your logins or otherwise snoop on you, and you'd never know.
"The consequences are hard to overstate. A remote attacker running a malicious proxy could capture their victim's HTTPS traffic and record credentials for later re-use," he said. "If a site needs two factor authentication (such as a one-time password), then the attacker can still hijack a live session by cloning session cookies after the victim logs in."
The first issue is due to AntiTrack not properly verifying HTTPS certificates, allowing an attacker to self-sign certs for fake sites. The second issue is due to AntiTrack forcibly downgrading browsers to TLS 1.0, and the third is due to the anti-tracking tool not honoring forward secrecy.
Separately, the Avast antivirus tool potentially has another vulnerability. This time, Googler Tavis Ormandy has found the antivirus suite running its JavaScript interpreter with system administrator-level privileges, which is like running around with a gun in your pocket and the safety off.
"Despite being highly privileged and processing untrusted input by design, it is un-sandboxed and has poor mitigation coverage," Ormandy said of the process. "Any vulnerabilities in this process are critical, and easily accessible to remote attackers."
I recently installed avast! free antivirus and it kept giving me a warning that some file (bootloader or something like that) had a warning because of it's "decompression rate". After some research, found out it was harmless and recommended that I uninstall avast! for an alternative. So I uninstall avast with the uninstaller it came with, however, now when I check my console log, every 10 seconds it shows a log for "com.avast.helper" that says "Error connecting to master socket: connect ( ) : No such file in directory". How can I permanently stop this, and possibly remove any remaining fragments left from avast!? I tried going into my library, but the application folder for avast! was no longer there.
Open Avast! Preferences and uncheck or "open" File System Shield and disable it. (If you are on line and not downloading anything, then you are still protected. I disconnected from my router to do this stage.)
Return to finder and select the first part of the system pass and get it to allow you to choose that path as part of the exclusion. That will copy the path to the "Exclusion" window on Avast! It may take trial and error to get it to appear, but you will get at least part of it to move. Then you can edit and add the rest of the filepath to the exclusion window.
After you do this, either click done, or repeat the process until all the inaccurately identified files are added. You can also add the entire Library or other folder to the exclusions, but I suggest not doing that, since in the unlikely event you are infected with malware, it might go unnoticed.
Most OS X applications are completely self-contained "packages" that can be uninstalled by simply dragging the application to the Trash. Applications may create preference files that are stored in the /Home/Library/Preferences/ folder. Although they do nothing once you delete the associated application, they do take up some disk space. If you want you can look for them in the above location and delete them, too.
Some applications may install an uninstaller program that can be used to remove the application. In some cases the uninstaller may be part of the application's installer, and is invoked by clicking on a Customize button that will appear during the install process.
