With the AVG Firewall switched on, it is not possible to contact the email client (using Outlook). The AVG Help facility has been useless (both inbuilt and via their customer support agents). AVG now want to have access to my computer via the Internet in order to interrogate it directly themselves in order to trace the problem.
My immediate reaction was "no way" because I have commercially- sensitive data on my HDDs, not to mention all my banking and investment details.. They say that I can monitor their activity and switch it off at any time, but how do I know that whoever is doing the interrogation cannot later gain access again without my monitoring it?
Am I being paranoid do you think?. I am not suggesting that the AVG company itself would be party to any nefarious activity.
