How long it has been around isn’t the issue, conflict is the issue.
I have been using Avast Free of over 15 years and as long as it has had the Behaviour Shield that too has been running without problem. My only concession is to set it t Ask (like if have for all shields).
But it does not give you achoice of what to do in !each case! or !per program!, which means you are not in control…and that is a joke.
It does, as mentioned by Dave you can set it to “Ask”. Further, you can’t compare a HIPS with a BHS, different things.
I was asked to restart my computer this afternoon by Avast. Before restarting my Avast version was 19.8.2393(19.8.4793.545) and my GUI was 1.0.437. After a restart my Avast version is 19.8.2393(19.8.4257.546) and my GUI version did not change. Curious to go from…4793 to …4257. Any explanation ?
Not seen any request to restart, so I can’t really comment.
However, it isn’t unusual to see minor version (build number) updates as the Virus Definitions updates also include the ability to update Engines. That said it is unusual to see the build number go down.
you are right. avast did the same with me today and after restarting my system, i had issues with smart scan. when i run a smart scan, avast closes itself and the tray icon disappears.
Hi,
Exactly the same here - on opening Avast, it told me that “Avast needs to restart your computer” (Which it does every now and then). On restarting, I opened Avast from the system tray icon, and hit the “Run Smart Scan” button. After about 1 second, the GUI disappeared, and the system tray icon went as well. I can start Avast from the Start Menu, but it will still do a disappearing act if I try to run Smart Scan. The Program Version is 19.8.2393 (build 19.8.4257.546), and I am running 64 bit Windows 10.
Hopefully this will be fixed soon - a virus scanner that doesn’t scan is rather like having a chocolate teapot!
Cheers - Henry
Confirmed and reported to Avast. Let’s see if that helps.
Acknowledged by Avast. and has been given highest status to be fixed asap.
I’m glad I’m not the only one who is experiencing the frequent “Avast needs to restart” messages. The last time this happened to me was years ago, but it was throwing me the restart message upon EVERY reboot, so I just uninstalled Avast, and then reinstalled it after a fresh reboot, and then I no longer got that frequent restart message. I think it got stuck in a loop.
I was asked to restart my computer this morning. The version number has been updated 19.8.2393 (version 19.8.4793.547). Thanks Avast
Once again I was asked to restart my computer this morning and the new version is now 19.8.2393 (version 19.8.4257.548). Back to 4257 once again instead of 4793. What’s going on ?
For some reason Avast cancelled an update and reverted back to old version.
Because of that numbering is messed now but it’s just numbering, nothing to worry about.
From Avast,
“Hello there, please be informed that yesterday we released fix the previous update was targeted to but was reverted as mentioned above. However, the program version will be (again) reported as 19.8.2393 (build 19.8.4257.548)and although it is not as it should be, we leave it on this number for now. Next program update will adjust the build number back to the standard numbering. Thank you for your understanding.”
Is this where I keep up to date on the newest Updates? I take it this will be shown as the first Post in the Thread when it comes time?
I didn’t even realize that it is only Upgraded once a year?! I thought is was at least twice a year?
Thanks

I just saw that Avast Free 19.8.2393(19.8.4257.522) thinks that HitmanProAlert3.8.1.863 is a virus
