It CAN NOT be removed by the Add\Remove programs applet. It is insidious and keeps badering you to buy a symantec subscription even if you have removed all symantec products from your system. I've talked to several people and no one can figure out how to remove it. NEVER BUY A SYMANTEC PRODUCT or any machine that comes loaded witha symantec product unless you want to be badgered every day you use it to buy a $100 subscription you don't want. Talk about a computer hack!

Required for Symantic's Security Suite. Does not remove with the Symantic Uninstaller, and will hamper use of any other security software if not wanted.

Best practices for resolving PIFSvc issues

A clean and tidy computer is the key requirement for avoiding problems with PIFSvc. This means running a scan for malware, cleaning your hard drive using 1cleanmgr and 2sfc /scannow, 3uninstalling programs that you no longer need, checking for Autostart programs (using 4msconfig) and enabling Windows' 5Automatic 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 6resmon 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 7DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.
