Microsoft
has always had quite a reputation when it comes to security updates and
software upgrades and the latest April 2019 Patch Tuesday update is no
exception, with reports of units freezing during the update process and some
hanging in the middle of startup after the patch is applied. The culprit? Conflicts
between the recent patch update and the antivirus software, which affected many
Windows operating systems, including Windows 7, 8.1, Windows Server 2012 and
2012 R2.
Microsoft,
Sophos, Avira, and Avast have already addressed and brought light to the issue through
their respective support articles. They say that the conflict is largely
between recent updates and certain components of antivirus software systems,
including Sophos Endpoint Protection, AVG Business Edition, ArcaBit, Avast for
Business, CloudCare, and Avira Antivirus. In particular, the patch caused computers
to hang or fail on boot, freeze upon startup, or run very slow.
Resolving
the issue is a matter of removing the updates from affected machines and you
can generally do so by booting in safe mode and disabling the conflicting
antivirus service and then booting in normal mode so you can uninstall Windows
KB. Do not forget to enable your antivirus service after uninstalling the
problematic update.
Because
these patches and upgrades can be technical in nature, it is always best to
seek assistance from your managed IT service
provider in order to perform recovery and repairs properly. With
the right service, you can rest assured that fixes are correct and won’t cause
any further problems for your system.
In
conclusion, despite antivirus systems and update patches causing some conflicts
with certain operating systems, there is no denying their importance in keeping
your applications and your operating system in general functional and secure.
Instead of avoiding or deferring these updates, keep yourself informed and on
the lookout for latest security news to brace yourself for the positive or
negative impacts of these patches and updates.
