First of all i use vista 32
firewall security custom policy mode
defense + clean pc
Comodo firewall last build
I use Comodo firewall more than a year now and never had problems
To make a long story short i tell my little problem
three months ago i bought a iphone so i had to install itunes but when installed it it didnt work
it missed some files as bonjour/mDSNRREPONDER file i have always the firewall settings like above
i tried everything but nothing did help. so i shutdown the firewall and installed itunes again and itunes installed perfectly. and i did it everytime there was a update from itunes.
Till three days ago there was a software update from itunes for the iphone itself but everytime i got error -3259
when i tried to download it. yes it downloaded it but when it finished i got that error so i searched what that code means you can read it here Resolve issues between iCloud for Windows or iTunes and third-party security software - Apple Support
so i shutdown the firewall again and tried it again and again i got that error then i uninstalled the firewall and tried it again but still that error so i thought it was a mistake from itunes and installed the firewall again .
did tried yesterday again 5 times but still that error tried today 4 times but everytime that error
till i thought i disable defense+ and disable the firewall and so i did and yes it downloaded and istalled it fine.
so i had the same problems with quicktime couldnt even install it but this time i disabled defense + and yes i could install it but the player doesnt work, on some webpages i can see movies but on apples page not
so i had always problems with the install of microsoftsoft silverlight and yes i disabled defense+ and it works
so can that be a bug in defense + that it block files without prompt me or is it just me
and yes i always switched to installation mode while installing something.
