Hi everyone, I've just had a rather disturbing event transpire that's never happened at all: My entire system (Running Windows 7 x64) completely hard-locked on me for several moments. Eventually I regained control, but investigating my system logs and looking at ESET revealed that NOD had crashed horribly, and restarted itself. I've never had NOD crash on me before, though I admit that in the last three weeks I've upgraded from an earlier version of 4.X to 22.214.171.124. Is this indicative of my being infected with anything? Did something kill NOD so it could play nasty games? I was running Opera at the time, but it was operating inside Sandboxie. My NOD information is as follows: Code: Virus signature database: 5758 (20110104) Update module: 1031 (20091029) Antivirus and antispyware scanner module: 1293 (20101110) Advanced heuristics module: 1115 (20101116) Archive support module: 1123 (20101108) Cleaner module: 1050 (20101207) Anti-Stealth support module: 1023 (20101125) SysInspector module: 1217 (20100907) Self-defense support module : 1018 (20100812) Real-time file system protection module: 1004 (20100727) In the event viewer, during the crashes, I see: Code: Faulting application name: ekrn.exe, version: 126.96.36.199, time stamp: 0x4cd2d774 Faulting module name: ntdll.dll, version: 6.1.7600.16559, time stamp: 0x4ba9b29c Exception code: 0xc0000005 Fault offset: 0x0002e1fe Faulting process id: 0x604 Faulting application start time: 0x01cbac18b8b782b0 Faulting application path: C:\Program Files\ESET\ESET NOD32 Antivirus\x86\ekrn.exe Faulting module path: C:\Windows\SysWOW64\ntdll.dll Report Id: f75fa3f0-180c-11e0-822a-001fbc01945b And Code: Fault bucket , type 0 Event Name: APPCRASH Response: Not available Cab Id: 0 Problem signature: P1: ekrn.exe P2: 188.8.131.52 P3: 4cd2d774 P4: ntdll.dll P5: 6.1.7600.16559 P6: 4ba9b29c P7: c0000005 P8: 0002e1fe P9: P10: Attached files: C:\Windows\Temp\WERD2F2.tmp.appcompat.txt C:\Windows\Temp\WERD380.tmp.WERInternalMetadata.xml C:\Windows\Temp\WERD381.tmp.hdmp C:\Windows\Temp\WERD44D.tmp.mdmp These files may be available here: C:\ProgramData\Microsoft\Windows\WER\ReportQueue\AppCrash_ekrn.exe_5cafdb419b39a302b95eedcc5235e7e1e346185_cab_053ad498 Analysis symbol: Rechecking for solution: 0 Report Id: f75fa3f0-180c-11e0-822a-001fbc01945b Report Status: 4 Any help with this would be appreciated. I'm not sure if this is something seriously wrong, and I need to panic about infection, or if it's just a fluke, and everything is OK. Thanks.
