I found out that my auto-update for avast! is off, I went to settings and still after checking automactic updates, still it’s off. I ran a hijack log and nothing seems to change. :-\ I check Zone Alarm Program settings and it’s allowing avast to update. I can do a Manuel update which is no biggy, but I can’t set it back to auto-update. :-\
I’m using the 4.6.684 Beta
Everything is fine for me…
No settings changed…
Maybe you must make the changes, exit avast (shutting down the providers and answering ‘No’ to persist) and only after that booting again.
Ciao, Fixer! 
Open the avast4.ini file and check if VPSUpdate is on “AUTOMATIC”.
Kamulko! it says it’s automatic and it’s running.
Tech, I did it and reboot my computer but still didn’t work. I also tried to repair avast! and that too failed. Strange, it says that it’s running, nothing change. I also run a hijack log and I didn’t get any changes.
Did you checked the Services Panel?
Wait wait wait, I think I got something. I went to avast4.ini again and boom it’s set to Manuel. So I type in Automatic then run avast! and now it’s on. But when I click on “On” it turns off. So I went back to avast4.ini and had to type in Automatic again to turn it on.
Hey run avast and click on the “On” text next to automatic updates. :-\
… I’m waiting for your final check… thrilling… suspence… :)… hope all run fine after the next reboot!
I think it’s on now (It said it’s on), but why does it turn off when I click on the “On” text next to automatic updates? ???
I suppose the ‘nothing’ change is not related to the beta version of avast…
I mean, can’t you update or it’s just a problem of ‘on’ and ‘off’ weird thing?
What says the Avast! Registry Viewer (“errors”)?
I can still update avast! (thank goodness) It’s just after clicking on “On” it turns off Automatic update.
Does any other option become ‘on’ when the Automatic become ‘off’?
Neither of the three options stay ‘on’? ??? :
So far no, if I even click on settings, it will turn off automatic updates. Nothing seem to turn it on.
Weird… Are you working simultaneously with avast4.ini file opened in Notepad or not?
You’ve said the repair procedure did not help… it’s really weird…
Yeah, I open avast4.ini file with notepad.
In the Program Settings GUI → Update/Connections, you see “dial up” or “always on” (I don’t know what the English GUI shows to you)?
I try that Kamulko! and still they turn it off. Right now, I’m not gonna touch the settings cause it turns off Automatic Update for some reason. Gonna keep working at this problem.
mmm… I’m suspecting a defect in the related GUI/Avast4.ini… now I leave… tomorrow I will take a look here again. Hope you can solve the problem, Friend.
Ciao… and good luck 
Okay guys I finally solve the problem, it was the XML and ODBC database. I switch back to ODBC cause I was using XML for quite a while. After switching back to ODBC, they kept the Automatic Updates On after clicking on it. Now it’s back to normal, thanks for all your help guys.
Perhaps it is acting like a toggle switch. If the updates are already set to automatic it is switching them to manual, give it a try and see if it acting like a toggle without having to edit the avast4.ini.
