"ui failed to load" --> repetitive

Avast Free Antivirus / Premium Security
1

hello,

i have often the avast icon (free version) that become disabled (red cross) when i want to open the main window it displays “ui failed to load”.

i have searched on internet a lot of time for this issue. many people have/had it.

  • some fixes were to enable the “remote desktop” windows service.
    the 1st time the problem happened i have activated this service and indeed avast has enabled.

  • some days later, the problem reappeared but this time the remot desktop service was already enabled. so it was impossible to reactive avast with this way.
    the other solution i read in the forums was to “repair” or “update” avast but this doesn’t work for me

  • the last fix i have read is to uninstall and reinstall avast.
    i have done it, avast has indeed worked again… but only few days, because today morning the problem reappeared…

what can i do else? i cant uninstall/reinstall one time a week, it takes too much time.

is it possible that an avast member team can help me please?

thanks

ps: i use windows 7 pro 64 bits and i have zone alarm firewall.

update: when i right-clic on the avast icon and choose the option update, a window appears, in this window when i clic the “update” button i have a message from avast that the rpc server is not available.
maybe it could help for the diagnostic

I’m also having this issue. I noticed it happened after I updated my Windows 10 to the 1803 April update.

Get rid of ZA and try again.

ZA is not an antivirus (it’s a firewall), the article you show me is to uninstall other antiviruses.

Meanwhile, ZA is both, that’s why it’s listed in the FAQ article.

no i have not the antivirus module of zone alarm. this is for zone alarm premium offers and i have not this.

at any rate when i open the main windows of zone alarm it is written “antivirus is available but not installed”.

here is the picture

Anyway, I’d suggest to get rid of ZA, the W7 FW is sufficient.

it is not the subject of my topic but anyway i answer for this. i dont use w7 firewall because i don’t have the requests for connections programs. it’s not at all as convenient as zone alarm.

the firewall doesnt interfer with the antivirus i dont think we have to focus on this.

and i am not the only person who have this problem, sadly the problem is elsewhere.

Well, the final decision is yours, I’m not here to convince you. Good luck.

yep i didn’t come for a replacement program of zonelabs products but for asking help for avast product.

i wish i’m on the correct location ^^

I too… and this started with the 1803 April Update.

Yes mines down as well after the April update from MS.

Avast please help.

@ calliefgrace , Sotomonte , Happychappy

avoid the “same for me” on topics where the causes doesn’t seem the same

ahahah issue here is on windows 7 pro 64 bits , yours is about the last update 1803 on W10.

There is obviously a problem with this update which concerns a lot of users and a more appropriate subject
