## Controversies
### Independent test results

Until approximately 2016 McAfee suffered from poorer malware detection test results and a larger impact on PC performance.
Since end of 2016 with the introduction of AI and machine learning detection technologies initially called McAfee Real-Protect and nowadays known as McAfee Smart AI, the test results have changed significantly though. AV-TEST (Germany) awarded McAfee with a TOP Product certification in the last 27 tests, SE Labs (UK) gave McAfee an AAA rating in the last 24 tests and AV-Comparatives has been certifying McAfee win an ADVANCED+ rating in its Real-World Protection tests since July 2022. AV-Comparatives has also rated McAfee as ADVANCED+ in almost all Performance tests since October 2016.
In January 2025 AV-Comparatives published it's 2024 Summary Report in which it awarded McAfee with two Gold awards: the 2024 Real-World Protection Gold Award and the Best Overall Speed Gold Award.
AV-Comparatives’ Real-World Protection Test measures a product’s ability to combat malware under everyday conditions. Winners of this test, such as McAfee, provide high levels of protection with minimal false alarms, sparing users the stress and burden of identifying whether something is harmful.
The PC Performance Test evaluates the impact of a security product on system performance. McAfee showed the lowest impact on PC performance of all tested vendors throughout 2024.

### 2010 reboot problem

On April 21, 2010, beginning approximately at 2 PM GMT, an erroneous virus definition file update from McAfee affected millions of computers worldwide running Windows XP Service Pack 3. The update resulted in the removal of a Windows system file (svchost.exe) on those machines, causing machines to lose network access and, in some cases, to enter a reboot loop. McAfee rectified this by removing and replacing the faulty DAT file, version 5958, with an emergency DAT file (version 5959) and posted a fix for the affected machines in its consumer "KnowledgeBase".

### 2012 update issues

An August 2012 update to McAfee antivirus caused the protection to become turned off and users to lose internet connections. McAfee was criticized for not notifying users promptly of the issues when they learned about it.

### Current standing

Over the years McAfee product reviews have been steadily improving with PCMag rating McAfee+ with 4 stars out of 5 and TechAdvisor awarding McAfee security with an Editors' Choice award.
