I put a lock screen password In Samsung galaxy j5 but It was not working and when I tried to change password it is not accepting my password? Two days ago I was attacked by spam on Facebook. When I changed my password and logged back in, Facebook said that I was attacked by a malware, and need to scan with the Eset online scanner, and provided an Eset app, but it isn't running on my PC. So I am now unable to login, as the scan is required. What should I do?
