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 flaws affect both the Avast and AVG versions of AntiTrack, and punters are advised to update their software as a fix for both tools has been released.
