I have ESET Smart Security 5.0.94 installed on Win XP SP3. Recently, any time I try to launch ESET, the splash screen will appear for an instant and disappear. Also, the ekrn.exe service is no longer running, which I thought it was supposed to do when ESET was active. I went to the ESET site and successfully ran an online scan of my PC and drives. It only found and removed two low-level problems. Other parts of the ESET suite will launch just fine. Any tips?
