I think somebody introduced a virus code in the blockchain ..

But I'm not sure if it is possible ?

Its possible and it has been done. In fact it allready has been done a long time ago in the testnet.
See here https://bitcointalk.org/index.php?topic=554738.0
where on of the devs talks about it. This also links to a swedish board where this is discussed.

Also getting a positive for Virus:DOS/Stoned, but in Bitcoin\chainstate\285512.sst, from Microsoft Security Essentials.

Running Windows 7.

I believe I've also seen threads about this before, trying to dig up the relevant information...

There have been similar posts here:

Maybe this should be in some sort of sticky or this will pop up again and again.
well... it probably will anyway.
