When I installed Avast 6 it installed, against my express wishes, the Avast gadget, which replaced the clock and calendar. I've uninstalled the gadget, replaced the pre-existing gadgets, followed instructions on these forum. No result. I uninstalled Avast and the ****ing gadget was still there. I'm stuck with either no clock or an Avast-branded one.
I'm now searching for an Avast uninstall tool to completely remove all traces of Avast from my system. I'm not prepared to use software which installs advertising on my system
