hi,,, to find out more about what failed look in event viewer,,, just type it into the search box in start menu,,,, there will be more info in there,,, copy the relevent bits and post them back here,,,
i found this on google about what you posted,,,fssfltr.sys,,
FSSFLTR.SYS is related to Windows Live OneCare Family Safety Driver.
Manufacturer: Microsoft Corp.
if you have live one care,,, update it and the drivers to.
if on the other hand it says this,,,fsflt.sys,,,, then this is malware and comes from a nastie called winantivirus spyware,,,
if its this then do full scanns with mbam and sas,, free versions,,,, download both install and update then full scan,,,http://www.malwarebytes.org/mbam.php
,,,, malwarebytes,,, green button for free versionhttp://www.superantispyware.com/
hope this helps,,,, but first look in event viewer to check what it says.
