If you have a windows pc you should be aware of this.
Almost 97% of users use windows and rest use ubuntu, mac etc, because ubuntu, mac, linux these operating system are considered to be safe, the reason behind this is only 3% of majority use these operating system so nobody creates virus for these OS.
But what can you do If you use Windows? WIndows is easy to hack and anyone can steal your data through internet and you even wont get to know about it, so in my opinion if you do not play games in your windows or your windows is for only pc use, you must try other OS and you will be addicted to them because they are difficult to hack and this is the reason army and militory do not use windows, but in case you cant change your windows purchase the best antivirus like kaspersky they do not let others steal your data.
