I have a brand new HP computer with Windows 7 Home Premium installed.
I have installed the latest ZoneAlarm Free Firewall (Version 9.2.102.000).
Using Internet Explorer 8 (8.0.7600.16385), I download the Opera browser (http://www . opera . com/download /get.pl?id=33345&thanks=true&sub=true). The file is saved on my harddisk with a size of 8.982 Kb. When I try to run this executable for install, I have error messages from windows ("Non 7-Zip archive" or "this is not a valid Win32 application").
When I uninstall ZoneAlarm and do the same, the downloaded file has a size of 9.110 KB and executes correctly.
Any idea ?
