Malware - Vista Antispyware Purchase

[J123t]

Hello
Have AVAST registered as my antivirus, but last night the Avast symbol was replaces by the Vista sheild and now I cannot use the internet at all, am being pointed to purchase Vista antispyware....?  Look from work internet today, I see this may be malware?  Not very good technically........why did Avast fail to recognise this, and how can I get rid of it
