Security for Vista sp1 / Win 7

In case you don't have either of those operating systems and you're in no way planning to use them then you don't need to read this.
But if you do ..well here's the story.
Along with the first service pack for Vista Microsoft also launched a new set of APIs for developers to use. One of these APIs is used for communication between your Antivirus/Antispyware software and the operating system. Most software developers had implemented and used the older version of the API, but with the release of the new set and service pack 1 they would have to change to the new ones.

Now ..Microsoft gave developers an original 18 month grace period in which both the old and the new APIs would work, but that period ends. ( btw grace period started when you installed SP1 on your machine) Well in september the grace period will ends and yu may start receiving warnings about it.

What it all actually means?
Don't worry your antivirus software will still work, the only difference is that Windows won't know that. Windows will just tell you that " is on but is reporting its status to Windows Security Center in a format that is no longer supported. Use the program's automatic updating feature, or contact the program manufacturer for an updated version". ( screenshot below)

What can you do?
1) nothing because it;s all the same
2) Update your antivirus software as most companies have already implemented the new set of APIs and everything will get back to normal.
