Hi guys
I remember about three weeks ago, the number of virus definitions in the database about the 4 035 000. Now avast shows 3 992 528. These were all false detection?
Whilst the above link and information is old avast is constantly optimizing the virus database so that scans can be completed promptly.
They might well have reduced the number of definitions it isn’t reducing the effectiveness of the virus database.
That’s why i leave Avast! product for few times.And join when a new beta come and the number of virus definitions is raise.It is 5 years old blog post.
??? :
Thanks Pondus and DavidR for explanation. I wonder because of Avira has basically in local000.vdf (virus def file) over 130MB (without daily incremental vdf files) and Avast has three vps size together something over 100MB (without streaming upd). Avast is great of course, but i was curious how it is. Thx again guys.
I suggest that you read the replies again.
It doesn’t matter how old it is the function of spring cleaning/optimizing continues all of the time.
If that wasn’t done the number would be massive and that makes things unwieldy and could slow scanning.
The signatures that are in there because of the optimizing many are capable of detecting more that one virus or variant of a virus or piece of malware.
@David i dont think it will sink in as it have been explained a couple of times before

You’re welcome.
Just check your C:\Program Files\AVAST Software\Avast\defs\ folder and you will see the VPS (virus definitions) database 15082400 is today’s and that is 110MB and that is with optimization mentioned, imagine just how big it would be without optimization. Avast periodically does housekeeping removing old VPS folders after the new one has been compiled.
The point of the streaming updates is to get new signatures out to users as quickly as possible, rather than wait for the next VPS to be released. These VPS updates will have all those streaming updates previously released ans possibly some others and some other functions (scanning engine updates, etc.).
It is more for the benefit of others viewing the topic, who can understand the concept of optimization of the virus database.
