I bought BitDefender software
Claims on task manager to be using 18 percent of resources, but the computer was unresponsive. Ended task and everything went to normal.
Hogs up CPU for over 10 seconds at 100% for things that use to happen instantaneously. More problem than a virus
  Bill S  
A critical process required for BitDefender Antivirus to run, this process carries out realtime scanning of accessed files, so dont be alarmed if it chews up your CPU when you open files and programs. It is a harmless process, but it could cause your CPU to heat up due to it's excessive resource hunger.

sometimes stays at 40% to 55% of cpu for a few min.

Best practices for resolving bdss issues

A clean and tidy computer is the key requirement for avoiding problems with bdss. This means running a scan for malware, cleaning your hard drive using cleanmgr and sfc /scannow, uninstalling programs that you no longer need, checking for Autostart programs (using msconfig) and enabling Windows' Automatic Update. Always remember to perform periodic backups, or at least to set restore points.

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off repairing of your installation or, for Windows 8 and later versions, executing the DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.

To help you analyze the bdss.exe process on your computer, the following programs have proven to be helpful: Security Task Manager displays all running Windows tasks, including embedded hidden processes, such as keyboard and browser monitoring or Autostart entries. A unique security risk rating indicates the likelihood of the process being potential spyware, malware or a Trojan. Malwarebytes Anti-Malware detects and removes sleeping spyware, adware, Trojans, keyloggers, malware and trackers from your hard drive.
