Thanks kia cat for your up-date.
Adaware is an Anti Virus Programme which has infiltrated your computer and no doubt has been conflicting with AVG. The worst thing one can have are two AV programmes which can cause all sorts of problems.
Even if you have now removed a number of Adaware file it is possible that the AV programme is still hidden in your computer. This is where you need to check 'Programmes and Features' in your Control Panel.
