MultiDetail, or MultiDetail 1.0, is a malicious Mac application and browser extension. It’s a symptom of an adware infection, probably one that came with a fake software update from some malicious pop-up ad. MultiDetail may change its name after you try to remove it, but it won’t go away until you delete its related files.

In short about MultiDetail:
|Installing MultiDetail||Pop-ups for fake software updates,

|Infection symptoms||Unstable apps,
adware comes back after being removed.
|Removing MultiDetail||Delete related files and profiles,
remove malware with anti-malware tools (Combo Cleaner, Malwarebytes, others).
How adware spreads
Most likely, MultiDetail was downloaded in an adware bundle from some malicious page and installed manually. Full-page pop-up ads that say “download Flash Player” or something similar are often used to spread serious malware. Few sites require Flash Player anymore, but cybercriminals still use its name, since it is widely trusted. Except, instead of Flash Player, they download a malware bundle that includes MultiDetail.
It is possible to get infected in other ways, like by downloading an application from a suspicious website. Malicious applications sometimes get bundled with benign ones, and there are some fake apps that use the names of trusted programs.
If you have even the tiniest bit of doubt about the safety of the file you just downloaded, it is good to scan it with an anti-malware app. MultiDetail should be detected as adware.
One issue is that adware infections really help other malware to infect your computer. That’s because adware like MultiDetail have really low standards for who they will take money from and what they will advertise. This helps scammers and other malicious actors reach more victims. So, it’s best to remove MultiDetail as quickly as possible. And any time you suspect an adware infection, don’t ignore it – check it and make sure.
MultiDetail is adware
While your Mac is infected with MultiDetail, you might notice these symptoms:
- changed browser search settings and changed homepage,
- more than normal ads,
- unfamiliar sites opening randomly,
- apps crashing, needing the Mac to be restarted to work properly again,
- internet connection dopping or being slow.
MultiDetail adware changes your browser settings. You might not see it in your browser extensions, even though it is installed there. MultiDetail may change your default search engine to Any Search Manager or another alternative search site. This allows MultiDetail to force you to go to affiliated sites, which ultimately makes money for the people behind this adware. It also allows MultiDetail to read your data and track your browsing habits.
In some cases, victims of MultiDetail may have their network settings changed in such a way that their traffic is routed to go through a server set by MultiDetail. You can see your settings in System Preferences, Advanced Network Settings, in the Proxies tab. If there’s a proxy set that you don’t know about, that could be a bad sign. This could also cause your internet connection to be slow and unstable, and make your apps crash often.
Another issue is that MultiDetail may be kept on your Mac by a malicious Profile. Check your System Preferences again: is there a section called Profiles? Unless your Mac is controlled by an administrator or an organization, there shouldn’t be one. If there is, check all the profiles listed there. If any of them mention Any Search Manager, Safe Finder, or anything else associated with MultiDetail, remove it by pressing the minus button.
Finally, there are probably some files in your system folders that shouldn’t be there. Open your Finder, Go, Go to Folder, and paste in these addresses:
- ~/Library/Application Support,
- /Library/Application Support,
Look for files with suspicious names, like AddUpgrade, UpgradeAgent, SkilledDeskSearch, ExploreSearchResults, etc. Then look up those names online. Don’t delete anything unless you have made backups and are sure that the file is not trusted.
How to remove MultiDetail
Until the profile and the files that force MultiDetail to be added to startup are removed, MultiDetail will come back every time you start your Mac. But you can start it in safe mode, blocking unnecessary apps from running. This limited mode lets you troubleshoot issues and remove malware more easily. You can start your Mac in safe mode by holding the Shift button while booting it up – until you see the login screen.
Find and delete malicious files and profiles like mentioned in the previous section, or use an anti-malware program to find them, such as Combo Cleaner, Malwarebytes, etc. Either way, it’s advisable to scan your computer with such a program to check if you have any suspicious files or apps on it.
Finally, you should be able to remove the MultiDetail app from your Applications folder and the MultiDetail extension from your web browsers.
