I tried to install Avast Anti-theft on a rooted Galaxy Nexus. It jammed up because of Handcent SMS. I then uninstalled Avast and reinstalled Avast. Now it has a universal no symbol ( circle with a slash through it)on anti-theft and I can’t try to install again. Any help appreciated!!!
Right now antitheft depends on SMS to be activated and other SMS tools are incompatible. Maybe you could uninstall it and install avast antitheft again.
