Not good to tag along on a topic with three years since the latest post and the topic created almost nine years ago.

The avast versions will be completely different. So any suggestions offered here are unlikely to work. Outside of this error has been related to having another AV installed or remnants of you previous AV left behind.

So it would be best to create your own new topic, sans very large coloured text, not needed to get help.

In that topic answer the following question - Have (or did) you another Anti-Virus installed in this system, if so what was it and how did you get rid of it ?
