>Recently my work machine start displaying this message in the lower-right corner. On top of this, many of the feature and windows application start working. This included IIS and ODBC drivers. I have search the web for possible solutions but found nothing legal or even worked. Now, this last weekend my machine at home is doing the same. I know for a fact that my home machine is a legal copy of WIndows 7, for I bought when got the machine earlier this year. Has anyone encourtered this and found a solution short of reinstalling the OS and applications?

Did you consider that both your machines maybe infected with malware/viruses?
