I did the AVG 7-5 dance a while ago - it is free.

Like JiK, I too have done the Spybot S&D update dance too...

My dialup is currently running at 52000 (a Wommera modem with an lcd screen!) - I can get up to 53333, sometimes drop to 48000. This modem fully speed autoranges, and has auto line quality detect.

I have my 98SE 'System Monitor' set to show 'CRC errors' 'Incomplete Frames' 'Overrun Errors'.
