您得到IRQL_NOT_LESS_OR_EQUAL：
http://msdn.microsoft.com/zh-cn/library/ff560129%28v=vs.85%29.aspx
IRQL_NOT_LESS_OR_EQUAL错误检查的值为0x0000000A。这表明Microsoft Windows或内核模式驱动程序访问 DISPATCH_LEVEL或更高版本的分页内存。

IRQL_NOT_LESS_OR_EQUAL (a)
An attempt was made to access a pageable (or completely invalid) address at an
interrupt request level (IRQL) that is too high. This is usually
caused by drivers using improper addresses.
If a kernel debugger is available get the stack backtrace.
Arguments:
Arg1: a4f0500d, memory referenced
Arg2: 00000002, IRQL
Arg3: 00000001, bitfield :
bit 0 : value 0 = read operation, 1 = write operation
bit 3 : value 0 = not an execute operation, 1 = execute operation (only on chips which support this level of status)
Arg4: 804e2def, address which referenced memory

PSUAMain.exe称为驱动程序，该驱动程序尝试以无效方式（错误的IRQL）访问页面内存。
首先将Windows XP更新为Sp3 +所有更新。您仍在2004年的Sp2 RTM上！！！！
Windows XP Kernel Version 2600 (Service Pack 2) UP Free x86 compatible
Product: WinNt, suite: TerminalServer SingleUserTS
Built by: 2600.xpsp_sp2_rtm.040803-2158
接下来，更新AV套件（PSUAMain.exe = Panda AV），看看是否可以解决。
