Norton has never reported any malware, and I don't have any ESET software installed.
Hi JL3008:
I don't want to take this thread off topic, but I only referenced the ESET support article Blue Screen Error (BSOD) on Systems with ASUS/Gigabyte Motherboards with Chipsets H87/Z87 and H97/Z97 because it explains how ASUS/Gigabyte utilities can cause your system to crash or become unstable. See the following threads in the Norton forum where users experienced BSODs when their Norton antivirus ran a scan (I post in that forum as user lmacri). The BSODs stopped when they uninstalled Norton, but an analysis of their dump files showed that the crashes were actually caused by a poorly written ASUS/Gigabyte driver gdrv.sys used by the EasyTuneEngine utility. The problem just became more noticeable when they ran a virus scan with Norton because of the intensive read/writes and memory allocated to Norton during a scan. The third thread discusses a problem with the ASUS Network iControl utility that resulted in dropped network connections after a Norton upgrade.

From the ESET support article: "AI Suite (ASUS) and APP Center (Gigabyte) applications use drivers thatcreate memory-mapped I/O to access hardware ports in a non-standard way. If the memory is subsequently read by another process utilizing aW indows API function (for example, during a memory scan by ESET), it may have unpredictable results on the system and the system may crash..."
I have no idea if the chipset on your ASUSTeK M2N8-VMX motherboard came with utilities like EasyTuneEngine or ASUS Network iControl, but the moral of the story is don't assume your antivirus is responsible if your system crashes during a virus scan or your network connection becomes unstable after an antivirus upgrade, and don't assume a Windows Update component is corrupted if you see a 8000FFFF error message when Windows Update runs. Run the proper diagnostics first and make sure you understand the root cause of the problem before you start making changes to your system that could do more harm than good.
