Ron, have always admired your work and wish others were as enterprising as you!

On Norton antivirus: Great product but when dealing with an existing virus you've got to clean the system before installing. As Moncha mentioned there are tools available from www.symantec.com. I'm the IT guy for a national bank and cover about 500 computers/40 servers over four counties. The higher-ups decided to go with McAfee a year ago and now we've been working almost three-days straight chasing bugs. Ironically we're using a Norton tool to remove the viruses so McAfee can work! Wish we were back on Norton!
