About viruses what not detected by avast.

How fast the virus analytics adds new sigs from virus@avast.com ?

Where also i can send this viruses?

You can send suspicious files to virus@avast.com
Put the file in a password protected archive and mention the password in the body of the email. Usually the password is virus or infected.

I don’t know what the reaction time is. I sent a couple of days ago a suspicious file, but no response, or detection.

Strange man’s … we help them to do avast better antivirus but they are freezing =))
All this viruses i’ll have check at virustotal.com. and avast wasn’t in report
