Until then, ZecOps states that there are two ways to stay safe: disable the Mail app (Apple has a guide here) and use a third-party app instead. Notably, it found both Outlook and Gmail are not. Several Mac users have reported that the Mail app window just pops up randomly and for no reason. Are you also having this problem on your Mac? This short article explains how you can stop the Mail app from keep launching itself automatically while using the computer. This is an annoying problem because it will interrupt what you are doing.
To use a Mac effectively, you need to free yourself from the Windows mindset that every computer problem is caused by a 'virus.' A 'virus' should be the last thing you suspect, not the first.
Please test after taking each of the following steps that you haven't already tried. Stop when the problem is resolved.
Back up all data before making any changes.
Step 1
If you use iCloud Drive, please open the iCloud pane in System Preferences. There is a checkbox marked iCloud Drive, and next to that, a button marked Options. Click that buttion, and in the sheet that drops down, uncheck the box marked Mail if it's checked.
This Mail checkbox is not to be confused with the one, also marked Mail, that appears when you first open the iCloud preference pane. They have different effects.

Step 2
If Mail crashes or freezes immediately on launch, try the steps suggested on this page. Sometimes a corrupt message on a mail server can be deleted by logging in to the server through its web page.
Step 3
If Mail still won't launch, or if you can't take this step for any other reason, skip to Step 4.
There are three types of mail account: IMAP, Exchange, and POP. You can determine the type of each account by opening the Mail preferences window, selecting the Accounts tab, and then selecting Account Information.

If you have IMAP or Exchange accounts, and you don't store sent, deleted, and junk messages on the server, export those mailboxes the same way. You can determine whether the messages are on the server by selecting Mailbox Behaviors in the Accounts tab.

Also export all mailboxes in the On My Mac category.
You don't have to export the other mailboxes, because the messages are stored on the servers.
Quit Mail.
Step 4
In System Preferences, open Internet Accounts (OS X 10.9 or later) or Mail, Contacts & Calendars (OS X 10.7 or 10.8). Make notes of the settings for each mail account (all types), then delete the accounts.
Step 5
Quit Mail if it's running. In the Finder, hold down the option key and select
Go ▹ Library
from the menu bar. Move the following items (some may not exist) from the folder that opens to the Desktop:
Application Support/AddressBook/MailRecents-v4.abcdmr
Containers/com.apple.corerecents.recentsd
Containers/com.apple.mail
Containers/com.apple.MailServiceAgent
Containers/com.apple.share.Mail.compose
Mail
Note: you are not moving the Mail application. You’re moving a folder named “Mail.”

Launch Mail. It will behave as if you were setting it up for the first time. Go through the setup process with one account, using the information from Step 4. Test. If Mail works now, recreate the rest of the accounts (if you have more than one) and other settings.
Any custom stationery that you created may be lost. Ask for instructions if you want to preserve that data.
If there’s no improvement, quit Mail and put back the items you moved to the Desktop, replacing any newer ones that may have been created in their place. Stop here and post your results.
Step 7
If you took Step 3, import the mailboxes you exported (see the support article linked to Step 3 for instructions.) Typically, the process takes a few minutes, but it may take hours if you have gigantic mailboxes. In that case, you may be able to speed things up by temporarily adding your home folder to the Privacy list in the Spotlight preference pane. Remove it when Mail has finished importing.
The mailboxes that you didn't export should synchronize automatically with the server. Again, if the mailboxes are very large, downloading them may take quite some time, and network performance will be slower than usual during that time.

If you skipped Step 3, look inside the Mail folder on the Desktop for a subfolder
Mac Mail App Virus Update
V3/Mailboxes (for OS X 10.11 or later)
or
V2/Mailboxes (for any older version of OS X)
Import the mailboxes it contains.
Test. If Mail is still working, delete the items you moved to the Desktop in Step 5.

Re-enable the Mail option in the settings for iCloud Drive, if you disabled it, and test again. If you weren't already using iCloud Drive with Mail, there is no need to enable it now, unless you want to.
