Windows has stopped recognizing DVD/CDRW drive, although BIOS is able to detect it. PCANDIS5.SYS has a registery entry but is not on hard disk.
Often associated with wireless networking

Sometimes my computer will not open ANY programs OR windows task manager for a while. Windows Defender tells me that a change has been made in PCANDIS5 and after it tells me that change has been made, my computer allows me to open things.
(using windows defender) My computer would not allow me to open any programs till PCANDIS5 made some kind of change (which took roughly 2-3 minutes after startup) it was quite annoying. So i removed the file, the problem stopped, and everything still worked perfectly. (any my printer still worked even though the file is said to be a printer related file)
