Some suggestions for other tests which could be used in connection with the updates.

Hi,
I've just joined this forum to give, what I think would be a wonderful anti-virus valuation benchmark.
May I please suggest these tests to you?
1. How often the AV companies roll out their updates.
2. How quickly they add new viruses to the defs.
Why am I asking this? Well the reason is that I have two computer, one my own with AVAST and another with AVG. I have noticed that AVG releases updates more frequently than AVAST and add new viruses more quickly than them too. In fact I sent several unknown viruses, received via email, to virustotal.com to be confirmed and then to AVAST yesterday morning. Only one of these viruses has been added to their database the others are still clean (according to AVAST). It's now over 36 hours later and for them to be STILL called "CLEAN" is dangerous.

Your thoughts on this would be gratefully received and even more so if really implemented.

My link in the AVAST forum is here

Thanks for your time.

Update

This is a very good thing I believe because it is no good if an AV is at detecting viruses but doesn't update the databases on a regular basis. If the AVs database is out of date, how can it detect newish viruses.
My problem is still continuing. It is now 84 ( EIGHTY FOUR ) hours since I reported this virus to my AV company. It has been confirmed by virustotal.com but it is still coming up clean by my AV!!! ;(

Hi, how often updates are released does not tell anything how many or how fast new malware is added. A company could release 5000 updates at day, each one covering just 1 (old) malware, while another may update just once at day but add 20000 new/current malware. Also the cloud says nothing about speed, unless they just add the samples to the cloud without properly analyzing the files (and take again out the files from the cloud if complains are observed). How fast your sample will be added may depend on what priority they give to you or to the sample, e.g. based on your license type (home or business), if you provided a valid license at all, if you told that you are infected by the malware or if you just found it somewhere and you are not actually having a problem with it. If the AV company considers it as having no priority, the sample may be even added in some months/years or not at all. But since you know it is malware, why bother. What would be more helpful would be good heuristics to spot new/unknown malware in advance, so e.g. the retrospective test would be more useful than couting the number of updates per day.
