Calendar virus Removal Tutorial

Use the following guidelines to get rid of Calendar virus on Mac. You will need to eliminate suspicious components from several system folders, move unwanted applications to Trash, delete shady profiles and login items created by the potentially unwanted program. Once you complete these steps, follow the instructions how to clean each affected web browser individually.

Eliminate components of unwanted program from Mac system folders

1. Click Go in the Mac's Finder toolbar and select Utilities.
   
2. Here, double-click Activity Monitor app.
   
3. In Activity Monitor, you will need to identify suspicious and resource-consuming apps, select them and click the X (Stop) button in the upper left corner of the window. Our suggestion is to search for Mac Security Plus, Spaces, BeAware, ScreenCapture or ScreenSaver apps and similar ones.
   
4. After clicking the Stop button for an app, you will see a prompt asking do you really want to quit this process. Click Force Quit to continue.
   
5. Now, click the Go button in Mac's Finder toolbar and select Go to Folder...
   
6. Here, enter /Library/LaunchAgents and click Go.
   
7. Look through the opened folder for suspicious components that possibly belong to the Calendar virus. Our recommendation is to look for unrecognized and recently added files. Then, move them to Trash/Bin.
   However, malware names hardly ever signal that they are somehow malicious, so you might want to check some questionable names online. For instance, examples of Mac malware related files include com.DataSearch.plist, com.ExpertModuleSearchP.plist, com.pcv.hlpramc.plist, com.updater.mcy.plist, com.avickUpd.plist, com.msp.agent.plist and similar.
8. Using the Go to Folder feature, navigate to a location called ~/Library/Application Support. You can simply copy and paste this path to the go to Folder window and click Go.
   
9. Here, identify suspicious folders and move them to Trash. Again, you need to use your common sense and look for recently added programs that aren't related to Mac OS or apps you installed willingly. Examples of unwanted folders include SystemSpecial, IdeaShared, ProgressMatch and DataSearch.
   
10. Use Go to Folder feature once more to navigate to ~/Library/LaunchAgents.
    
11. Here, identify suspicious components and move them to Trash.
    
12. Now, navigate to /Library/LaunchDaemons and eliminate strange or suspicious-looking components possibly related to Calendar virus. Known examples of Mac-related malware store com.pplauncher.plist, com.ExpertModuleSearchDaemon.plist, com.DataSearchP.plist, com.startup.plist and similarly named files here.
    

Move unwanted applications to Trash

1. Click on Finder.
2. Go to Applications folder.
3. Look for suspicious applications you can't remember installing. Right-click them and select Move to Trash.

Remove unwanted startup applications on Mac

Delete malicious configuration profiles

1. Go back by clicking < or close the window and reopen System Preferences via Mac toolbar. Go to Profiles.

Examples of known malicious profiles include Chrome Settings, AdminPrefs, Safari Settings, MainSearchPlatform, TechSignalSearch, TechLetterSearch and similar. In example below, the profile includes a suspicious link, although it can contain a function to force browser changes when user tries to revert them.
