Hello David. Sorry to hear about the inconvenience caused. Could you please let me know which AVG product are you using and is it windows XP you are running on your computer? Thank you.

Same problem on AVG Internet Security 2014.0.4830, but the fix by doing a Repair on the AVG program does not fix it, unless the subsequent update introduces the Trojan horse again.
