Actually, the anti tracking wasn’t working properly. No matter where I went, it showed no one was tracking me. In the AOS settings, the box for safe zone was ticked and greyed out, but I didn’t have safe zone installed, and a corner of the AOS panel was consistently missing on a particular site. See http://forum.avast.com/index.php?topic=144806.msg1050499#msg1050499.

The loss of the green ticks remained after a complete uninstall, cleanup (avastclear.exe, RajZor’s utility) and reinstall of 2014.9.0.2012, as did the ticked and greyed out safe zone setting, and no tracking was being shown.

Now I’m back on 2014.9.0.2011 the Web-rep ticks are back working again and the AOS panel shows I being tracked are expected, so they both appear to relate to the 2014.9.0.2012 beta.

The missing corner of the AOS panel when I’m on http://www.asx.com.au (Australian Stock Market site) also occurs in 2014.9.0.2011 so that hasn’t been introduced in this beta.
