A."Avast" is perhaps the worst of the whole wretched lot of commercial "security" products for the Mac. Not only does it fail to protect you from any real danger, it throws false warnings, destabilizes and slows down the computer, and sometimes or always corrupts the network settings and the permissions of files in your home folder. Removing it may not repair all the damage, and neither will Disk Utility or even reinstalling OS X.Back up all data, then remove "Avast" according to the developer&#x27;s instructions. Restart.If you tried to remove Avast by dragging an application to the Trash, you&#x27;ll have to reinstall it and then follow the instructions linked above.B.Some of your user files (not system files) have incorrect permissions or are locked. This procedure will unlock those files and reset their ownership, permissions, and access controls to the default. If you&#x27;ve intentionally set special values for those attributes, they will be reverted. In that case, either stop here, or be prepared to recreate the settings if necessary. Do so only after verifying that those settings didn&#x27;t cause the problem. If none of this is meaningful to you, you don&#x27;t need to worry about it, but you do need to follow the instructions below.Back up all data.Step 1If you have more than one user, and the one in question is not an administrator, then go to Step 2.Enter the following command in the Terminal window in the same way as before (triple-click, copy, and paste):sudo find ~ $TMPDIR.. -exec chflags nouchg,nouappnd,noschg,nosappnd {} + -exec chown $UID {} + -exec chmod +rw {} + -exec chmod -N {} + -type d -exec chmod +x {} + 2&gt;&amp;-This time you&#x27;ll be prompted for your login password, which won&#x27;t be displayed when you type it. Type carefully and then press return. You may get a one-time warning to be careful. If you don’t have a login password, you’ll need to set one before you can run the command. If you see a message that your username "is not in the sudoers file," then you&#x27;re not logged in as an administrator.The command may take several minutes to run, depending on how many files you have. Wait for a new line ending in a dollar sign ($) to appear, then quit Terminal.Step 2 (optional)Take this step only if you have trouble with Step 1, if you prefer not to take it, or if it doesn&#x27;t solve the problem.Start up in Recovery mode. When the OS X Utilities screen appears, select          Utilities ▹ Terminalfrom the menu bar. A Terminal window will open. In that window, type this:resPress the tab key. The partial command you typed will automatically be completed to this:resetpasswordPress return. A Reset Password window will open. You’re not going to reset a password.Select your startup volume ("Macintosh HD," unless you gave it a different name) if not already selected.Select your username from the menu labeled Select the user account if not already selected.Under Reset Home Directory Permissions and ACLs, click the Reset buttonSelect           ▹ Restartfrom the menu bar.
