avast died.. atleast half dead

Avast free version only requires a registration to activate ....however, malware could always compromise your system, so I would suggest that you please follow the instructions in the below link and attach the requested logs when you finish these instructions.

READ & RUN ME FIRST. Malware Removal Guide

 

As said...it is possible that malware is stopping the anti-virus programs from running ...I suggest you follow the instructions given and then when we can see what is going on in your computer, we may be able to clean you so that you can install / reinstall avast.

 

I'm not seeing any malware....

You have tried downloading Avast ?
Once you do the free registration, it is good for a year ....and then you only need re-register...perhaps you need to post in the software section.
