Windows update did not find common ground with popular antiviruses


The next April Windows update for all versions of the operating system, starting with the "seven", began to conflict with popular antivirus products. If your computer has antivirus protection installed, the new Microsoft patch slows down the entire system or it just stops loading. McAfee users were the first to find the problem, but later it spread to other antivirus solutions.

The latest Windows security updates are not compatible with McAfee Endpoint Security Threat Prevention 10.x and McAfee Host Intrusion Prevention 8.0. This also affected the software solutions Avast, Avira, AVG, Arcabit and Sophos - when installing new patches, PCs start to slow down.

McAfee, whose users of the antivirus of the same name were the first to raise the alarm, conducted a small investigation and found that the version of the operating system itself does not affect the problem. Third-party antiviruses and the latest Windows update conflict both on the basis of the seventh Windows and the G8. Owners of the tenth Windows and McAfee antivirus also found a glitch on their devices.


The main culprit of the problem was at least two patches - the KB4493446 package for Windows 8.1 and KB4493472 for the 7. Avast and McAfee managed to find out that packages make changes to the CRSS.exe file, which then begins to conflict with third-party antiviruses.

Microsoft is engaged in troubleshooting and recommends that anyone affected by such a nuisance try to boot the operating system in safe mode first, then uninstall the antivirus product, and then install it again. Also, one of the solutions to the problem may be to prohibit automatic updates using the standard operating system settings. In Windows 10, this feature is disabled by default, so you will have to use third-party software.

The Windows operating system has its own anti-virus products. Among them are integrated solutions Windows Defender Antivirus, Microsoft Endpoint Protection and Microsoft Security Essentials. Their management, including shutdown, is not always possible to make. The new Windows update, which turned out to be incompatible with third-party products, does not affect Microsoft branded antivirus solutions.
