I am not computer literate and need some help.I have the AVG free addition 7.1 and received a meesage that this is to be terminated in Jan 2007 to be replaced with the 7.5.version.I have tried to download this several time without success to date,I have the 7.5 icon on my desktop but this tells me that some files arte corrupted and try again.Could you please advise me how to go about this download from start to finish so that it replaces the 7.1 programme.Thank you for your anticipated reponse. bob 27
