What do other computer users say about PIFSvc?

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!

How to tell if PIFSvc.exe (LiveUpdate Notice service) was uninstalled cleanly

After uninstalling, restart your computer. Then start Windows Explorer and see if there is still a folder with the name of the software under C:\Program Files. Be sure to check the Registry as well for remnants of LiveUpdate Notice service. To do this, start "Regedit", then look under "HKEY_LOCAL_MACHINE" > "Software" for LiveUpdate Notice service or the name of the producer. Always keep in mind that only a computer professional should ever directly delete entries in the Windows Registry.

What to do if a program does not uninstall

The easiest way to remove any kind of software cleanly and accurately is to use an uninstaller tool. Because the uninstaller automatically creates a backup, there is no risk of anything going wrong.

Last but not least

If Windows not working quite right for you, or if startup is taking a long time, or PIFSvc.exe is causing problems for you, a good Windows diagnostic tool may very well help.
