Very similar problems recently and suspect that AVG are, indeed, dumping their free users. Have used them for years and I'm sure that until very recently they didn't have a UK website. They have now, and any attempts to update or install AVG free with them gets thrown out. Great pity - it used to be a very reassuring, unobtrusive AV program. Avast seems to work OK but one could NEVER accuse it of being unobtrusive!!
