Vlk,
Is not my intention to polemize about the uses of Venturi software and its potential advantages or disadvantages as they can easily be learned on
http://www.venturiwireless.com/ by watching their Flash presentation, whether right or wrong in their arguments, for a user like myself sound convincing enough, though, and the Verizon Wireless PC phonecard has been working for me in different portables, in many US environments from hotels, offices and airports and with other anti-virus flawlessly for almost two years by now.
I´ll be trying to update to VClient3.1 for Windows and I´ll see how it goes. If I can´t resolve the problem this way, I´ll try entering a bit in the guts of Avast4.ini as you suggest and I´ll keep you posted. The problem is that I´m not in the States at this time and I don´t plan to be there again before the beginning of October, security reasons permitting, of course..., and while possibly the software updating may resolve the problem, I will not be able to find out if the card connection will still be working though. Anyway.
Thanks.
