Hi artusa,
given the size of your license I think your best bet would be to take advantage of the upcoming “ADNM” http://www.avast.com/eng/adnm.html .
It will be released real soon (probably even this week).

With ADNM, all events are streamlined to a central location. Also, all updates are downloaded from local mirrors and you have a number of other advantages.

Please stay tuned.

PS. You may also want to have a look at the ADNM documentation http://files.avast.com/files/beta/adnmqs.pdf

PS2. ADNM is completely free for owners of a valid avast license (such as yourself).

Thanks
Vlk
