I have been getting bsod in my windows xp system since long, and I have been getting an error message which reads PAGE_FAULT_IN_NONPAGED_AREA and the problem file is DSAFLT.SYS. so thatís why I was just wondering if DSAFLT.SYS has anything to do with the bsod. So thatís why I went ahead and checked the location of DSAFLT.SYS and found them in 2 places. One of them is WINDOWS\system32\drivers and the other is Program Files\Panda Security\Panda Internet Security2011\FIREWALL. On doing some google search I found that both of them are not the proper location of the file. So I just want to know if DSAFLT.SYS is placed in some other location then will it lead to the bsod? Is it ok to delete the DSAFLT.SYS file? I am also having a panda security system is that anything related to the problem, please tell.
