Memory 16 GB G Skill Ripjaws Z DDR3 1866MHz / Graphics Card ASUS GeForce GTX 770 2GB X 2

Comodo Antivirus ( Product Version: 8.2.0.4508 / Database version: 21848 )
(Full PC specs are at end of text.)

Last night, Apr. 20, 2015, at around 11pm, I received a Comodo AV update pop up window so I ran the update. At restart, Windows started to load but froze. After 5 minutes, I forced the PC to shut down, restarted it, and the ASUS UEFI Bios Utility appeared stating that “Overclocking failed!” Please enter Setup to reconfigure your system. Press F1 to Run Setup.

I didn’t want to mess with any of the overclocking settings. I went into Safe Mode, ran chkdsk C: /F /R and sfc /scannow which ran without errors. Tried to restore system to a previous restore point and was unsuccessful. Tried accessing Safe Mode again and loading froze at windows\system32\drivers\CLASSPNP.SYS.

I had to use a Win 7 repair/restore disk to access System Restore and eventually found a restore date that worked.

I’ve since created a newer restore point where Comodo AV is disabled.

Are there any reports of issues with the latest virus database update?

Any suggestions on how to proceed?

I’m considering uninstalling / reinstalling Comodo Antivirus ( Product Version: 8.2.0.4508 / Database version: 21848 ) as it maybe corrupted or just incompatible due to recent changes… or maybe switch to another antivirus.

Before posting this topic, I did search your forum for any similar reports or help and didn’t find anything related.

your help is appreciated as this is my trading rig,

Paul

I am not sure if system restore and CAV logs interact. Can you check the logs of CAV to see what happened? That may give us a clue as to what was happening.

Hi Eric, thanks for the reply.

I need to mention that the restore point that worked was one where Comodo AV happened to be disabled.

I ran sfc /scannow and chkdsk again. Comodo AV was re-enabled, my PC was restarted and the same problem occurred as before … the ASUS UEFI Bios Utility appeared stating that “Overclocking failed!” Please enter Setup to reconfigure your system. Press F1 to Run Setup."

The only way to get my PC working properly was to use a Win 7 Repair disc and restore it to the date where Comodo AV was disabled. I’ve since uninstalled Comodo AV and therefore cannot check the CAV logs.

I think Comodo makes great software but this nasty crash means I will not be using the AV program for the time being.

thanks again,

Paul

FWIW: my Win2003 R2 platform is a TUV4X system board with socket 370 PIII-1400S 3x 512MB PC133 2-2-2-5 SDRAM @ 146FSB, Adpu160m dual-channel SCSI host controller 3x Fujitsu MAX3073NC 15k HDD, AGP GeForce2 GTS 64MB “enhanced” i.e., 5.5ns VRAM, w/ , video, CT4780 Sound Blaster Live! (w/ - yellow - digital-out jack).

So when I read about your prollems, I go: “Ha ha ha ha ha ha!” Notice how I’m laughing with you?

Really. :smiley:

Anyways, the thing you have to beware of when O/C’g is - believe me you when I tell you this - watch your memory O/C. You’ll garner far more performance increase per O/C tick by increasing the memory than CPU FSB. The very first symptom of O/C threshold exceedtion is CIS A/V defs update fail.

The way to discern whether or not one is pushing the memory sub-system beyond design tolerance is if Prime95 run to grimace-proportions fails. Another good indicator is whether 7Zip benchmark ever fails. Period.

CIS anything is injected into the boot pipeline very early during startup. The latest CIS technology is pretty exquisite - I’m very impressed and wish it’d run on 32-bit Win2003 - and I’d bet your farm that its very sensitive to one bit out of a bunch being in error. CIS insinuates itself very early into the boot-time startup pipeline and all those bits have to be perfect at startup. No way that you can lube the bit-stream past the latency tolerance of the entire pipeline.

I don’t know how you’re implementing the O/C, but if you’re using a util, e.g., PCI LatencyConfig, or Odo’s WPCRSet, or PowerStrip, that sort of stuff implements just before CIS injects itself into the boot-time bit-stream Very few things do. One thing that does is Ultimate Defrag boot-time NTFS meta-file defraggler.

I needs rules to allow that to continue; otherwise, while that’s running, CIS comes on-line and see’s that happen and throws a conniption. And I’ll bet my own farm: if my NTFS meta-file bit-stream gets mucked up I’ll make everybody around me an very unhappy campers. And I mean that nicely.

:-La

I believe that you’re tweaked too hard someplace - most likely the system board - and you needs to dial it back a tick or two.

I recommend that you find at stock FSB you tweak the RAM timings until ieither Prime95 or 7zip fail and then back off one tick on the one timing that matters. Now you can kick up the CPU. Don’t ever touch the RAM timings again except to slow any one timing down one tick to get higher stable O/C.

If you need to change any timing by two or any two by one: forget it. You just maxed out the RAM.

Once you find that number, you back off the CPU O/C by two ticks. And what you’re really after is the fastest timing of either CPU or RAM you can achieve stability with one less tick of voltage necessary.

Oh, and let this be something learned to you: always have full-sys image backups ready to go at a drop of a hat. :stuck_out_tongue:

Hi WxMan1, thanks for the detailed observations and suggestions.

So it seems you started laughing because you knew the cause of my problems right away. Thanks for clarifying that. :smiley:

This PC is used solely for trading options and forex and I didn’t input the settings on my custom PC, it was done by a local PC shop in Toronto, called Canada Computers. I researched what components I wanted and then they put it together as it’s not my area of expertise. However, I would like to load the OS and PC settings from scratch on another SSD. Could you recommend a web link that gives step by step instructions?

I do have an image of my OS using AOMEI, which is very easy to use, but it was not as current as the restore point I used. From now on I’m going to schedule AOMEI back up to image the OS weekly.

Out of curiousity, which imaging software do you use?

Also, which firewall do you use?

As mentioned earlier, I’ve uninstalled Comodo AV from this PC, but I do have it on my 2008 Toshiba laptop, which is working fine.

thanks again,

Paul
