Old AV Programs Cause BSoD Post-Vulnerability Update

Some AVs Cause Issues with Spectre/Meltdown Update

By: Jeff York

The recent Windows update designed to patch the Meltdown and Spectre vulnerabilities has been delayed.  The delay was to give anti-virus (AV) companies a chance to make changes to their registry to allow the update to install without causing blue screen of death (BSoD) errors during the update process.

PC Matic has already released a new version of SuperShield which has included the necessary changes to allow this important update to install without issue.  However, users must be cautious about any other AV programs installed on their device.  Issues may persist if AV software from an expired account is still be present after making the switch to PC Matic.  An expired program may not receive the necessary updates required to allow this critical update to run.  Therefore, even though SuperShield is updated, the other program may not be.  If this is the case, it will cause a BSoD error during the update process.
To ensure the computer is ready for the update, access the Installed Programs area of your Control Panel.  From there, ensure that PC Matic SuperShield is the only AV program installed. If users choose to run more than one AV program, it is important users ensure the recent updates for the other protective program are in compliance.

  1. Recently had boot problems on two Windows 10 laptops running PC Matic. One recovered from a system checkpoint and the other required a clean Windows 10 install. These problems did occur after some Windows updates, so this issue probably caused my problems. Although, I’m not running any old AV programs.

    • @John Graybill: I had the exact same issue was able to save one from a restore point and the other had to do a new install. HP computers with Windows 10 one a desktop and the other a laptop both purchased within the last year. The critical update seems to be a 1/10/2017 update of which there were two. Blue screened both computers. I amazed that there was not a lot more chatter about this.

    • @John Graybill: I’ve had the same issue on my desktop. Have had to restore 3 times now since the MS update and still don’t know how to fix the actual problem. I am not running any anti virus other them PCMatic and can’t find any indication anywhere that MS may have found during their update. PCMatic customer support indicated that I may have to reload some software, but I don’t know which ones. Sure don’t want to have to reload Windows.

    • BSoD stands for Blue Screen of Death. It’s a common term used when a Microsoft computer crashes because the screen that shows up is just a blue screen with an error message.

  2. Just returned a 60-day pls computer because of a BSOD issue. I wonder if it was related to this. Unfortunately, I could not get good help with solving it before I just too k it back. Lost new software installs and some data, not to mention the set up time for a new computer.
