New computer, installed AVG Free, scanned, no problems. ACER, Vista home Basic Then downloaded and scanned ZA, started the install, computer stopped the install, apparent conflict with something. Gives the option of Safe Mode. Had the same thing happen on a similar machine a few weeks ago, had to restart in Safe, don't remember what we did after that. I started in Safe, tried to find Zone Alarm to uninstall, doesn't show up in the programs in Control Panel. Help appreciated!
