|Hi Henksey (and Hi-5),|
If you had a previous version of AVG installed, which is what I had had and had uninstalled it (but not completely, as I later discovered) from the Uninstall option, or you had a part installation of 2011 after your attempts to download it, you could either download Revo Uninstaller, as advised by XpUser4Real (above) or download AVG Free Removal Tool to remove any AVG files and registry entries that were left behind, then download AVG Free 2011 again. Turn off any firewall/s you may have, and (especially) disable Zone Alarm if you have it, until after AVG has installed successfully - if you are sure you want AVG, that is - I did the installation for a friend's PC and laptop and AVG 2011 caused nothing but problems for him - the laptop slowed to almost a standstill and the PC stopped downloading updates after a couple of weeks and nothing would fix the problem. Take XpUser4Real's advice and go for AVAST. My friend is now using Avira, which seems to be ok, so far, and doesn't conflict with Zone Alarm.
