scan download files over HTTPS using Anti-Virus Proxy

[cc]

hi

I've setuped Anti-Virus Proxy HAVP+CLAMAV+SQUID on my debian etch stable.
with HTTP it seems to work, but the file download over HTTPS, for example from:

https://secure.eicar.org/eicar_com.zip

will be not scanned.
knows someone why and howto solve this problem using Anti-Virus Proxy ?

It will not scan https traffic as it is encrypted so nothing in between can read it eg your clam scanner, you could maybe decrypt your https traffic at your proxy so it could be scanned by clam then passed to the clients but .... Im not sure if squid can do this as I think it can only tunnel SSL.

thanks,

but knows someone howto setup squid to decipher SSL,
I mean to get SSL between a squid and remote server ?

p.s
I've setuped squid only for personal use.
