I have installed Kaspersky Internet Security 2010 on a pc and when I open my Mozilla Thunderbird mail program Kaspersky will turn off and it will block my incomming emails from
downloading. I installed kaspersky 5 months ago and didi not have any problem.
I tried to download a big file and that is where the problem started. I scan the computer for a possible virus, use malwarebytes and spybot but came out clean.
