"libecomlodr.dylib will damage your computer" popup removal from Mac

Find out how to fix the libecomlodr.dylib popup warning issue on Mac and get an idea of the possible malicious implications of this annoying activity.

The benefits of every new macOS version release aren’t restricted to bug fixes and improvements. It’s also about extra perks and features that add up to the awesomeness of the user experience. The latest 10.15.4 iteration of the much-spoken-of Catalina build is just like that. It introduces, among other things, the option to share iCloud Drive folders, a streamlined Apple Music lyrics view, and fancier methods to duplicate tabs in Safari. However, as it often happens, the operating system tweak isn’t flawless at the early stage of its implementation. One of the issues Mac users are encountering is the emergence of popup alerts that say, “libecomlodr.dylib will damage your computer”. These dialogs additionally include a recommendation to move the item to the Trash. The problem wouldn’t be such a brain-teaser if the “Move to Trash” button actually did what it says. Instead, the error message just keeps reappearing regardless and the users are stuck in a loop of popups.

The issue is about popups saying ‘libecomlodr.dylib will damage your computer

Upon initial look-through, it appears that the recent macOS Catalina update has changed the mechanism for flagging applications, processes, and files as suspicious or clearly harmful. This would explain the alerts blaming potential system malfunctions on the mysterious libecomlodr.dylib entity. The question arising at this point is, what kind of an item is causing the noxious alerts. A little bit of research reveals that libecomlodr.dylib is a component of Symantec Endpoint Protection for Mac. This is a popular security product by Broadcom Inc. that combines antimalware, firewall, and intrusion prevention functionality under the same hood. It can be deployed on desktop computers and servers alike and is often leveraged to safeguard enterprise networks against breaches and virus attacks. According to the vendor, if something goes wrong with the suite, the customers are advised to use a tool called GatherSymantecInfo that amasses the entirety of diagnostic data to facilitate troubleshooting. The artifact under scrutiny – libecomlodr.dylib – is one of the entries shown in this report alongside definfo.dat and usage.dat items.

With that said, it seems odd that a legit element of a reputable security solution raises a red flag. Some users argue that “libecomlodr.dylib will damage your computer” popup warnings are false positives. This could make sense, given that macOS Catalina has a controversial track record of overreacting to numerous apps, including benign ones. If a Symantec product is currently installed on a Mac and the alerts are making a mess of the user’s computing routine, one of the repair options is to check the application for updates and apply them if available. If this method doesn’t apply due to missing updates, another way to take care of the nuisance is to uninstall the security program and then install it from scratch if it’s needed. In many cases, businesses require that their employees have the Endpoint Protection solution installed on their company-issued Macs. One more technique worth trying is to go to the “/usr/local/lib” directory, spot the file in question, and send it to the Trash from there. If none of this works, chances are that the issue is in a completely different area.

The irksome popups reporting libecomlodr.dylib as a potential threat could as well be a consequence of Mac malware activity. The purpose of such alerts is to pressure the user into downloading more viruses or clicking on the button that’s some sort of an authorization request in disguise. This way, cybercriminals might be trying to distribute information-stealing Trojans or adware that will modify the browser settings to make the victims visit malicious websites over and over. If this scenario is the case, it’s recommended to use the following series of malware cleanup steps that will help eradicate the threat and stop the "* will damage your computer" Mac warnings from popping up.
