a new version of Bitdefender free antivirus is out
Is it compatible with windows 10?
Firstly you should download Bitdefender software from the main website and not any 3rd party sites.
At this time Bitdefender FREE is not compatible with Windows10. Should that change the main page for the product will be updated.
Bitdefender is popular all over the world, why you do not want to develop a free solution?
