Avast HTTPS Scanning, FireFox 67 and Certificates

[AZBruno]

I am now running Avast 19.8.2393 (build 19.8.4793.541) and Firefox 69.0.3.

I no longer have thousands of Avast certificates, although the MachineKeys folder still has 94 items... most as a result of Avast before disabling HTTPS scanning. Before I re-enable it, I was wondering if anyone can tell me whether the same issue will exist.

Thanks.

Hello,

The issue should be solved now. I would be grateful if you could verify it by visiting a few websites and checking that the number of certificates didn't increase.
If this is not the case and the issue persists, please let me know.

Thanks!

I've enabled HTTPS scanning and will monitor it.

Meanwhile, can you tell me the difference between "avast! SSL Scanner Cache" and "Avast SSL Scanner Cache". They both have certificates

[Jakub Dubovic]

"Avast SSL Scanner Cache" is the current name of the Avast certificate authority storage. "avast! SSL Scanner Cache" is now deprecated and will no longer be used when generating new certificates.

Edit: missed a word

[AZBruno]

So is it OK to delete all the certificates under the "avast! SSL Scanner Cache"?

Also, how can I delete the nodes of "avast! SSL Scanner Cache" and "avast!Mail Scanner Trusted" (which has no certificates now). I do not see a delete option for the nodes in the Certificates MMC snap-in.

[Jakub Dubovic]

Yes, they can now be safely deleted using MMC.

As far as I know, MMC doesn't allow you to delete the nodes. It can be done using regedit with the following path: "Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\SystemCertificates\avast! SSL Scanner Cache"
As always when using regedit, please do this only at your own risk and don't forget to create a backup first.
