Hello Sir,
I am using Windows 8.1 x64 on Samsung Gateway Laptop. I faced a very strange problem day before yesterday. Disk spaces of all drives except :C was suddenly getting filled automatically and disk space of drive :C was getting reduced automatically. When I turn on protected files option and looked into all drives then very much unusual files were present there and all were also hidden. After that I scanned my Laptop with a free antivirus, then it showed you have trojan. And now, today, problem is bigger than this. Today, files in all drives were getting deleted whenever I turn on my Laptop. That's why I am not turning on my laptop.
Sir, please help me as soon as possible. What should I do.
