Abaut avast2014, I would tried again, as it probably install process by itself gone some wrong or something was active in the background…etc
You may contact the avast support because you paid your license.

Reset your IE to there default settings and that should fix your problem.

To remove OTL and aswMBR just re-run OTL and click on CleanUp! button.

You will be asked to reboot the machine to finish the cleanup process, choose Yes.
After the reboot all the tools we used should be gone.
Note: Some more recently created tools may not yet be removed by OTL. Feel free to manually delete any tools it leaves behind.

Then re-run AdwCleaner and hit Uninstall button.
