The update to V. 21.5 has re-introduced the Mail Shield bug which prevents the Windows Mail App syncing email accounts. Tested on two devices so far and both required disabling Mail Shield to restore functionality to the mail app.

Not good enough, avast.

Edit: Issue now also confirmed as present on two more devices, turning mail shield off resolves it.

Edit2: 18/06/21 - Updated to build 21.5.6354.675 and issue with Mail Shield is now resolved.

Confirmed on Windows 10 Professional, latest updates and Thunderbird with both Yahoo! and GMail-based accounts.

I cannot access any mail via IMAP.

See this post (quote below) from Avast Team member:
Hi guys, we were integrating certificate processing code between MailShield and WebShield and this must have somehow slipped through the checks. We have seen this in the BETA and fixed it - well, at least that's what we thought!

The team is working on it while I type .... we'll update you here soon.

This appears to be a certificate issue. When I enable mail shields but disable IMAP / POP checking, I'm able to receive mail but not send mail. I need to figure out how to import the new certificate from Avast! I guess.

I can confirm. When enabling the MAIL shield but turning off IMAP scanning, I can receive mail. However, I cannot send mail, and Thunderbird reports an "unrecognized certificate" error.

Ouch!  This will teach me to wait a while before updating Avast.  I never did master deferred gratification.

I anticipate a correction being pushed out to all users.  Is this where emergency updates come in?

I have learnt to wait on virtually all programs that have an Auto Update function.

It could also be delivered using the Engine and Virus Definitions update, don't know which they would choose.

Just updated to latest, but on the status page it keeps on saying important update available, when I click update now it shows it has the latest update. But still red status with exclamation mark. If I choose to ignore then the status goes green.

Is this a bug in the latest release?

Dev-Info: We were finally able to induce issue with "Important update available" info in UI of up-to-date product on our machines.

Can you please check this registry value?
HKEY_LOCAL_MACHINE\SOFTWARE\AVAST Software\Avast\properties\settings\Common\ProgramUpdateAvailable=1

This value should be related to this issue. Please let me know if value is present in your registry. You can also manually change it to 0 (with disabled Self-Defense) as temporary workaround. It should help. We will try to fix it as soon as possible of course.

The Mail Shield issue seems to be fixed in Version 21.5.2470- Build 21.5.6354.675. It works for me.


The new build number isn't shown after triggering a manual update. Try a reboot, then it should be deployed.

The Avast 21.5 free offline installer seems unchanged from the one I downloaded before the mail certificates issue was realised so I have to ask if that bug will still be installed if I run it.  I routinely archive each offline installer.  Perhaps I will give the one for Avast 21.5 a miss this month.

I would suspect that when using the installer it would also check for emergency/other updates.

Whilst saving a copy of the off-line installation file is wise I still saved the 21.5 off-line installation file), but you shouldn't need to run that every time there is a program update available (I didn't).  So in this instance using the on-line installation file would appear to be the way to go if having done a manual program update, the build number isn't the latest.

@loungehake, you should be ok, no need to wait til next month. I just (30 mins ago) downloaded the offline free installer and got the 675 version straight out of the box, so to speak. Only the normal restart, no repair/restart required.   :)

Mail issues are solved but Avast 21.5 seems distinctly sluggish compared with 21.4.  Is this just my mistaken impression?

Ever since the new build I am now getting behaviour and ransomeware shields failed to load and sometimes the password shield.
Program version :- 21.5.2470 (build 21.5.6354.679) Avast Premlum
Virus Definition version :- 210701-4

Have uninstalled using the avast tool and reinstalled ofline version then updated.
Doing a search seem this issue has been around for a while even with the correct version.

I am supporting a customer who insists on using Avast Free Edition and it blocks all incoming mail using Windows 10 Mail (blue envelope).  No emails received since 12th June!  The error code in the app was 0x80072f0d.  This relates to a certificate error and the account which it fails on is a plusnet.com email address.  The error code resolution was to turn off the Avast Mail shield.  My customer has Outlook 2019 installed and that is not blocked by Avast Free edition - but I cannot persuade her to use this superior email program!  If you could resolve this I would be grateful.  If I had my way I would move her onto Outlook but she won't budge.  I will remote into her machine tomorrow to check the Avast versions and update to the above one to see if this resolves it or if she is on the same version.  Thank you for your help

After some update a couple of weeks ago the Mail Shield has started to tag and quarantine an automated mail from one of my business partners as Virus, even thou it is not, and it was never tagged like this before the update.

It uses the - HTML:Url-inf [Susp] as the reason for this action.

The mail content is moved to Quarantine, but when I try to Restore it I only get the “Whoops, error occurred.” message.

The mail is clearly available in the quarantine vault, since I can restore it to a file and manually take it from html to eml and open it again in Thunderbird just fine.

I tried adding the senders domain to the Exceptions, but that had zero effect, since the mails are still tagged and quarantined.

So, WTF is happening with the Mail Shield on this new update?

Thanks for the link, which said that this was fixed in the 28.06 update, but it was still happening at least on 02.07 for me, with everything updated, so I have sent a False Positive message on the link provided in that thread.

Regardless of this False Positive issue, that still doesn’t explain why these quarantined mails can’t be restored from the quarantine vault, but get an error instead.

Whilst this isn't directly related to this avast program version, but the virus signatures that would apply to even earlier versions.

See extract from a reply I made in another topic.

###
This is where it becomes very unclear for me, if it is found to be an FP and this is an email (it doesn't really have a file structure) or an email attachment I don't know how these are dealt with.  For a bog standard file it can be placed back in the folder it came from and you should be good to go.  But for an email file or attachment, many email programs don't hold emails individually but in the inbox, etc.

This is basically a big file (possibly compressed) and outside of that folder you can't just insert it back in there as it could corrupt the whole folder, which could result in the loss of the emails in that folder.

I don't know what today happen, but my Chrome now work normally. For long time my Chrome was slow, delayed and sometimes just frozen completely. I suspect it was caused by Avast, because i reinstalled Chrome, disabled HW acceleration, disabled all extensions and nothing helped me. Now works perfectly without any change in my PC, chrome version is same as yesterday and yesterday was my Chrome very slow and freezing. So it is sad if Avast need many months to fix this issue. I am on Win 7 64bit Avast Free.

Personally I never thought that this would ever come as Avast Free would become a serious competitor for Avast Premium as there isn't much more in that I would really want.  This now has essentially become Avast Pro of old, the AV + Firewall.

Dev-Info (Consumer Versions): Please note that the Anti-spam feature was removed in the last update. We strive to provide the best protection possible, and our research and comprehensive review of the feature showed that Anti-Spam wasn’t offering enough value to our customers. Given that email providers nowadays provide strong embedded anti-spam filters, we decided to focus our development efforts on adding value in other areas. Recently we introduced new features such as Remote Access Shield, Password Protection, improved botnet protection, etc. We think these new features — along with ongoing improvements to our other many features — provide advanced protection for our customers.

Dev-Info (Business Versions): Important! In this version, the Antispam feature is being removed, and will not be available in any edition of Avast antivirus. For the clients who will not update to 21.4, the Antispam feature will be remotely turned off by the end of June 2021. But don't worry! You are still protected from email attacks with our Mail Shield feature! This feature offers comprehensive email protection by proactively checking incoming and outgoing emails to ensure they are completely malware-free.
