|AVG should install on XP Home so I don't know what went wrong. I have seen problems in installing programs on particular computers (not just AV's), which I can only put down to a conflict with the software mix already existing. I regard AVG as a bit bloated so that might have some bearing on your problem too.|
If AVG it is causing issues then there is a lot of sense in going to another AV. As Avast is considered by many to be a better bet than AVG then I would endorse the advice already given. You will have to re-register the free version of Avast annually but that is quite easy to do.
I understand that AdAware do now offer a proper Anti-Virus, unlike their old product, but it is fairly recent. As they are (presumably) still in a learning curve then what I've said still stands. Better to run with what the forum members know is satisfactory.
Always pop back and let us know the outcome - thanks
