causes cd-drive to vanish.

installed with Sony Picture Motion Browser V2.1.00. Killed my Windows 7 machine. I could not reboot nor was the auto fix able to fix anything. The auto fix told me that pxhelp20.sys was corrupt. I renamed the file through the command line and now I can reboot. Not sure yet if I lost any functionality. I tried Gateway technical support first since this was a new computer they told me I had to ship the computer back to a service center to have it fixed. The person or persons who wrote this software should be fired or be requred to pay restitution to all of us who have wasted our time debugging our systems.

Avast! popped up a warning at the end of installing Winamp 5.5.8.2985. I followed the Avast! instructions, rebooted with a full pre-boot virus scan, and came up clean. Started Winamp, it invited me to upgrade to 5.61. Installed 5.61, and I didn't get any warning. Maybe installing 5.61 in the first place would have avoided the problem. PxHelp20.sys still shows in my C:\WINDOWS\system32\drivers folder :(

It's not a virus etc., it's just a stupid problematic and uwanted driver. PxHelp20.sys (ver 3.00.93.0 no digital signature) appeared on my system most probably after installation of DivX Player Plus. At that moment, my DVD drive lost the ability to read/burn/recognize any Verbatim DVD media, TDK DVD+R, and some other. Even some discs burned+verified on my PC few weeks ago are inaccessible now! I canNOT read my own backup! Now, I am able tu burn only on old Sony DVD+/-R. On the other hand, it seems that problem with Kodak CD-R disappeared, not sure due to this driver. I'll uninstall DivXPlayer!

It's creation date and time is the same as most files in Winamp folder (Program Files). It bring "Lower Class Filter" to my DVD burner. Deducing, it supports Winamp burning capabilities. Drive filters change drive's behavior
