0x0000004A BSOD - Bit Defender ?

[JackNaylorPE]

Some time back I had several BSOD's with a 0x0000004A error code and using BlueSvreenView I examined the dmp file and went looking for similar error codes here in the forum and elsewhere. After a looking at the 1st 3 hits, these are 2 of them.

This is on a Clevo P170M laptop. Went thru BD TS and they pointed to several items not related to them such as an outdated netio.sys file (it wasn't, at least according to MS and WU). Among tese were:

KB2664888 - I don't have the problems described in that article
KB2913431 - According to MS, my version is correct.

Recently had another one and haven't had time to go thru the files line by line as yet but here's DM log file.

Hey there!

BugCheck 4A, {777fda2a, 2, 0, fffff88007691b60}

Probably caused by : ntkrnlmp.exe ( nt!KiSystemServiceExit+245 )

Run sfc /scannow and chkdsk /r.
Install the latest updates from Windows Update.

Do the exact same steps for chkdsk /r but instead of typing in sfc /scannow type chkdsk /r.
