From ur help in chat with avast links as of now I have added in Avast's behaviour shield exclusion for outpost op_mon.exe. Lets c what happens, will check 2moro.
Next steps would be in this sequence:
1. unchecking the 'monitor the system for unauthorised modifications' option in the behaviour shield, expert settings
2. disabling behaviour shield
3. uninstalling behaviour shield
4. uninstalling other shields
5. uninstalling Avast
