Did that, but it won't allow you to install in Safe Mode! Says operation cannot complete in Safe Mode
Anyway, looked about on Google for help and found some stuff on AVG's free help forum. Which is all well and good, but in order to post you need to register. And you can't register without installing AVG Free and using the "forum register" link in it! Nice one! I need help installing, but can't ask cos I haven't installed the fooking software that I am having trouble installing that I need to ask about! Stupendous piece of idiocy there!
Anyway, one thing I read was from a person with identical problems - he said he changed the default name of the folder AVG creates during the install process. He said it then worked no probs...
So I did the same thing and lo and behold, completely sorted! Installed fine, updated and ran a scan!
How odd tho!
