MS Antivirus utility

I am happy to see that Microsoft has now realise the mistake they did when they stop their antivirus utility which they used on Windows pre Window 9x such as Windows 95. Their free downloadable antivirus utility from www.microsoft.com I hope will came to rescure to none technical Users who does not take into consideration to update their Antiviruses program often. The only issue I have with this utility is it active duration which is 10 days thereafter you have to download a new one. Acording to me 10 day seems to be pretty short but I hope they will extend maybe later to atleast a year active usage.
