Although antivirus programmes including Microsoft Defender, I can't detect any virus. Moreover, a folder of 2 GB deleted without my control from my computer which also includes important documents.
In the first month of my laptop, the same thing happened, and 20 GB deleted. It claimed that Windows 10 deletes certain folders by mistake.
Take an action for this disturbing situation. Turkey branch is not dealing without feedbacks and problems. I tried to contact with the customer service and help, but again it is not helpful or solved.
