Ok, I compressed the log with rar.
It is still an impressive 70Mb
I try to send it to the ftp.
Name: AVAST! 5 IS Firewall - huge log file - Att. of Lukor-Lukas.rar
see my notes in: Please note !.txt
Extra remark: in the last hour, while sending the file, the log file grow with 5mb
Good luck, and I always liked Avast very much.
Used the free version since 2004 at home !!
Now I have convinced the business to buy it, so don't let me down ! ;-)
