I used AVG 2011free, with daily updates, for many years on my win 7 computer, last week it starting telling me "unable to update definitions" and "unable to update program", so I thought it was just getting too old. I uninstalled it, then ran avg clear program to get rid of all old traces of the program.I have turned off my firewall, turned off my malware program and am still unable to install the new version. The install bar gets to the end, closes, but does nothing else, the program is not installed. Please help… getting frustrated…have tried many times, with same results, and clearing and restarting many times
