Trying to install the latest Avast on a MBA running 10.9.5. No sign of any problems. Machine running fine. I had installed Avast on another machine of his and it did some good, so he wanted it on his MBAir.

Avast Update Failed
You need to look up from the avast icon on your desktop and Open the shield’s control. In shields control, right-click on the Disable to disable the shields. You will get the option to disable it for 10 minutes to an hour. Disable it for 10 minutes and wait for 10 minutes and check if the ‘Avast UI failed to load’ issue persists. When you contact Avast Support to report that Avast Antivirus failed to install on your PC, you may be requested to provide a setup log file for further analysis. You can access the setup log from the Avast Setup wizard when you are notified of the error, then copy it to Notepad and save it as a text file to send to Avast support so they can.
Avast Installation Failed
The problem, the installer fails at the final stage with a completely generic message that's no help.
Looking at the console log, lead me to believe a couple things:
- Perhaps it was tripping over a permission problem.
- or perhaps it wasn’t happy that Chrome was not installed.

One specific log line item says (which might be the key if someone can interpret, my Google searches haven't been able to untangle):
Avast Installation Failed
'CoreServicesUIAgent: Error: qtn_file_apply_to_path error: Read-only file system'
So, here are the things the DIDN'T solve the problem
1) repaired permissions
2) installed Chrome
3) repaired home permissions
4) restarted
5) turned off Gatekeeper
6) redownloaded installer
7) ran Disk Repair, which led me to booting into Recovery Mode to fix a couple directory structure mismatches.
Any ideas what else it could be tripping up this install?
I don’t have enough experience with Avast to know whether or not this is an “Avast problem”, but I certainly have more experience with installing under Mavericks to say Avast is most likely the culprit here.
I suppose I could give up on Avast and go to ClamAV, but he’s “sold” on Avast. I realize there are other virus protection solutions and I realize there's some debate on whether or not anti-virus software SHOULD be installed on a Mac. Just looking for suggestions on the installation problem itself.
Have submitted a ticket to Avast, but only a canned response so far.
