You mistoke me. The Web has a lot entries regarding WLM not starting, without solution. Some mention vaguely a relation to exotic virus protections and other tuning softwares.

This post by the OP is about WLM and Avast. I can’t do without WLM 2011 or WLM 2012, but for AvAST there are alternatives. The replies are general knowledge regarding software XXX biting software YYY but not yet leading to solution.

Edit: even if WLM is at fault, the solution, or fix must come from the AV part. That’s reality.
