Hi guys , I have a Question : how can I set the avast to introduce mozzila thunderbird on the acces scanner, because avast in not searching my e-mails. Or maybe I did not put the question in order. however if you know a way to put thunderbird as a module , please tell me.thank you 
You shouldn’t have to, OS dependant, win9x, winME require manual settings others don’t.
What Operating System are you using ?
Thunderbird like other pop3 email clients is covered by the avast Internet Mail provider.
However, it also depends on a) are you downloading webmail using one of the thunderbird email add-ons, b) your email uses SSL (secure encrypted email) ?
Why do you ask ?
Presumably because you have a problem, if so what is the full text of the error ?
well ,David , I am using Windows Professional , SP3 , and I am using thunderbird for my gmail account. I do not have a particular problem , I was just wondering if avast has coverage over my e-mails too. thank you.
Gmail uses SSL secure email so avast can’t directly scan it that is the problem and the point of secure encrypted SSL to keep prying eyes out. It also uses a different port for SSL email and avast doesn’t monitor these ports, only the standard email ports 25, 110, 119 and 143.
Gmail does scan its own email, so the risk is negligible, but there is a tool, STunnel which acts as a third party so avast can scan secure email. This obviously has to be set-up and there are some posts I can point you at if you wish to do that.
I also don’t use gmail or thunderbird so have no practical experience in them, but I believe there is a gmail add-on for thunderbird and I don’t know if that imports the gmail as normal pop3 email, in which case it would be scanned. You can check the Last scanned: and Scanned total: fields in the Internet Mail provider, if it is scanning the gmail content these fields would reflect this.
avast 5 when released (date not given) will be able to scan secure email.
thank you verry much David , you have been verry helpfull.
No problem, glad I could help.

As noted in the past (yes David, you get a dispensation because you use neither and credit cos you remembered the function … you are doing well among us … seasoned … campaigners) the Thunderbird Webmail extension for Gmail does indeed convert the Gmail from the http site to a standard POP3 mail stream into Thunderbird that can be scanned by avast, but since it is delivered via localhost it is necessary to make that happen in avast by:
avast Internet Mail provider > Redirect tab > Uncheck “Ignore local communication” box > OK
Nevertheless - given the fragility of these extensions which easily break on any change to the Webmail sites I would recommend that (unless the POP/SMTP ports for GMail are blocked for some reason) Gmail users rely on the scanning done by Gmail.
We expect that avast 5 (when available sometime in 2009) will provide, within avast, assistance for those who want to have avast scan email that is delivered via secured ports to be scanned. We will have to wait and see how easily that is implemented.
Just as an afterthought - all mail clients, all mail servers work to the very rigid POP3 protocol … the choice is binary … there are normal POP3 mail streams or there are those that do not work.
Thanks Alan.
