Published by Sonic Solutions. Evil file, prevent either of my CD-ROM drives from working. Go through the registry and remove the lowerfilter entries for pxhelp20.sys to remove it.
  André Baron  

after removing this driver you have to edit the registry to remove it from the CD/DVD driver (upper/lowerfilter) or else your drive will fail to work! (this driver is AFAIK no part of windows!)

seems to be able to cause c000021a. logon procsess fatal error so you cant get your computer started. not 100% sure about this though, but since it starts during boot it could be very likely ?
  Huh  

ok, this thing screws up your drivers. also, there is more files than pxhelp20.sys, some of those files says it was created the year 2003 on your computer, it also looks like it keeps making more and more files not sure about that though. but i know my computer cant read any disks and that happend 2 days after i got this file. This file can come from Winamp, so make sure you dont have the check box on positve at audio support files, Sonic Ripping/Burning Support. also, i think this file can cause c000021a, fatal logon error. it also disable files but how many and what kind of files i dont know
  Huh  

It is a driver for CD and DVD rom drives. It's one of the worst ones out there but there's nothing to be concerned about, many CD writing software uses it. Do not get rid of it if it found its way on your computer, it's not a virus, it didnt get on there because you dont need it. Chances are you got it with software that requires it to work properly.

shitdriver. lets my cdrom vanish. disabled via deleting filter entry in CurrentControlSet for CDROMS (MS has an article). kill it!!!
   

The Sonic Solutions cd-burning engine is also installed now with Google's Picassa photo viewer (which offers 'backup', or burn-to-cd capabilities). Windows Vista will also use Sonic's engine to power its built-in burning feature (see http://www.cdrinfo.com/Sections/News/Details.aspx?NewsId=18759). Windows defender (free, available from microsoft.com) will prompt you when this driver is installed on your system... in contrast, Picassa is 'recognized' software and is allowed to install. With Windows Defender installed, you can choose to deny this driver when an application installs it.

I just installed a new DVD burner that came bundled with Nero 6 software which installed this driver. therefore, I would assume that Nero 6 will not work if pxhelp20.sys is disabled, however, my computer runs much slower since this was installed.
