Avast Service will not start.

Then you have to run it every day because no AV is running on your computer, good luck!

I'd love to have a AV running, but avast apparently is never going to work for me again.

You may consider it.

Ive had a lot of problems with this since the last update - it seems Avast is arguing with firewalls even if you white list them .

I have tried no avast - firewall works fine
No firewall - avast eventually loads 

Both together - firewall wont load and avast takes about 6 minutes to load ( service is running BUT avast reports it isnt , has a hissy fit , freezes computer then agrees it is running and lets me have computer back ).  I have MBAM but its on demand and I have disabled MS defender and firewall and use Commodo - There are lots of posts over on commodo about avast suddenly fighting commodo .

How about Windows Defender?

Obviously Defender is installed as it's part of the OS on win7, aside from Defender being next to useless it does not interfere with avast.

I recently had the same issues.  I tried everything and I decided to check out my Administrative Services area to see if Windows Defender was still disabled.  It was Not disabled and once again I disabled it, rebooted my computer and sure enough my problem was resolved.  Not to rock the boat with your reply, Windows Defender does interfere with Avast, at least it did with my computer. 

Thanks for your time and please enjoy your day or evening.

I checked it out through C:\Program Files\Windows Defender\MSASCui
