BSOD when using uTorrent on 64Win7

Related to tvicport64.sys TVicPort Driver from EnTech Taiwan. Yours is from 2005

Try looking for a bsod reader, it should tell yo what file/exe/anything is causing it.. (fixed mine because of it, i also get bsodnwith utorrent and the problem was my wlan card driver)

I would recommend posting your latest crash reports and letting us take a look. There may be new information to help narrow things down.

PFN_LIST_CORRUPT (4e)
Typically caused by drivers passing bad memory descriptor lists (ie: calling
MmUnlockPages twice with the same list, etc).  If a kernel debugger is
available get the stack trace.
Arguments:
Arg1: 0000000000000007, A driver has unlocked a page more times than it locked it
Arg2: 00000000001375d0, page frame number
Arg3: 0000000000000001, current share count
Arg4: 0000000000000000, 0

Due to the crash being network related, I am inclined to conclude the problem is due to avast! Please remove avast! using the avast! uninstall utility and replace with either

Microsoft Security Essentials - Free Antivirus for Windows

or the

Good and Free system security combination.

I am not 100% sure it is avast! causing the crashes, but it is a good idea to replace it at least to test.

Alright, run for a few days and let us know how the system responds. Best of luck!
