lsass.exe hogging processor on startup

December 9, 2009 at 11:49:02
Specs: Windows XP
Each time I cold start my computer, lsass.exe will require around 50% of the cpu time for about 45 to 60 minutes. During that time, the hard drive is continuously active. The burden of lsass.exe prevents any other apps from running smoothly until lsass.exe is done with whatever it is doing. Norton Internet Security suite returns a clean bill of health. The unit has done this for a very long time, so I have developed the habit of keeping it on standby overnight to avoid having to endure the start up processing.

Norton Internet security suite is a resource hog in itself. It's totally abnormal for this to occur. You are probably infected. Read this and try it.

Go to command prompt and chdir to c:\


attrib lsass.exe /s and see where it shows up. If in documents you are infected. rename file and reboot find usb drives and delete autorun.inf.

Also sometimes they hide it by not an L (ell) but an I (eye) which may look like lsass.ese but really isass.exe.
