Can I download some file from the Avast web site to update Virus Definitions on a standalone PC (no network connection of any kind)?
I was told some AntiVirus Products have a kind of “Virus Definitions Updates” that can be downloaded and then applied on standalone PCs
TIA

Yes you can. You would already have known the answer if you only had looked at http://www.avast.com
Yes you can - avast! VPS Update - Manual Download.
Welcome to the forums.
Thank you very much, for the answer and the warm wellcome.
Not sure yet of choosing Avast, is among my favorites but I have not made the decision, this one was one of the points to take into consideration not all the antivirus programs allow updating offline.

What are you waiting for?
What feature you need and already did not discover that avast! has too? ;D
Welcome to avast! 8)
Well avast is the most flexible, configurable AV that I have ever used and I’ve used a few. Not to mention it is relatively light on resources when compared to the behemoths out there.
Should you chose to try it, ensure that you uninstall (not just disable) your existing AV (especially if it is NAV, let us know as this often leaves stuff behind), two resident AV are likely to cause conflict rather than twice the protection.
well technically speaking,…you always have to be online to download them,…
Not sure if this relates to my comments.
However, if it does, I credit ‘bradmoss’ with the intelligence not to uninstall his existing AV before going on-line and downloading avast! before going off-line and uninstalling his existing AV and installing avast!
I want to know is it bad to have two antivirus program. I have Avast 4.6 and on-acsess always on and i have Antivir on my system but for Scanning my computer only and i disable the GUARD becuase Avast is already doing this. So its it bad to Have two antivirus program on your computer even if one is active and one is not? (Antivir is just there for on-demand scanning).
as long as you completely disable the realtime protection and do not scan at the same time i think you should be fine.
Thanks
Anti Vir and avast together (with Active Guard disable of course) should be fine. I had Anti Vir along with avast! a while ago and didn’t have any problems. 
With avast you can have (without activated residents): Antivir, BitDefender (free), ClamWin, NOD32 and McAfee.
Without even installing the residents (not just disabled): AVG.
NEVER: Norton Antivirus (NAV).
