Cannot get rid of offers4u

I tried almost everything to get rid of this thing offers4u pop. I've read through messages of others, downloaded Malwarebytes (Nothing detected), updated my system running, uninstalled and deleted firefox and then reinstalled again. There are no extensions or add ons that seem suspicious. Deleted files, others suggested the library. And IT ' S ALWAYS THERE! I am at a loss. Can someone please!

You may have installed one or more variants of the malware "VSearch' ad-injection. Please back up all data, and then take the steps below to disable it.

Do not use any type of product, "anti-virus" or "anti-malware" on a Mac. You have already seen that it does not work.

Malware is constantly evolving to work around defenses against it. This procedure works now, I know. It will not work in the future. Anyone finding this comment a couple of days or more after it was published should look for a more recent discussion, or start a new one.

Step 1

VSearch malware tries to hide by varying names of the files it installs. It regenerates itself also if you try to remove it when it is run. To remove it, you must first start in safe mode temporarily disable the malware.

Note: If FileVault is enabled in OS X 10.9 or an earlier version, or if a firmware password is defined, or if the boot volume is a software RAID, you can not do this. Ask for other instructions.

Step 2

When running in safe mode, load the web page and then triple - click on the line below to select. Copy the text to the Clipboard by pressing Control-C key combination:

/Library/LaunchDaemons

In the Finder, select

Go ▹ go to the folder...

from the menu bar and paste it into the box that opens by pressing command + V. You won't see what you pasted a newline being included. Press return.

A folder named "LaunchDaemons" can open. If this is the case, press the combination of keys command-2 to select the display of the list, if it is not already selected.

There should be a column in the update Finder window. Click this title two times to sort the content by date with the most recent at the top. Please don't skip this step. Files that belong to an instance of VSearch will have the same date of change for a few minutes, then they will be grouped together when you sort the folder this way, which makes them easy to identify.

Step 3

In the LaunchDaemons folder, there may be one or more files with the name of this form:

com Apple.something.plist

When something is a random string, without the letters, different in each case.

Note that the name consists of four words separated by dots. Typical examples are:

com Apple.builins.plist

com Apple.cereng.plist

com Apple.nysgar.plist

There may be one or more elements with a full name of this form:

com.something.plist

Yet once something is a random string, without meaning - not necessarily the same as that which appears in one of the other file names.

These names consist of three words separated by dots. Typical examples are:

com.semifasciaUpd.plist

com.ubuiling.plist

Drag all items in the basket. You may be prompted for administrator login password.

Restart the computer and empty the trash.

Examples of legitimate files located in the same folder:

com.apple.FinalCutServer.fcsvr_ldsd.plist

com Apple.Installer.osmessagetracing.plist

com Apple.Qmaster.qmasterd.plist

com Apple.aelwriter.plist

com Apple.SERVERD.plist

The first three are clearly not VSearch files because the names match either of the above models. The last two are not easy to distinguish by the name alone, but the modification date will be earlier than the date at which VSearch has been installed, perhaps several years. None of these legitimate files will be present in most installations of Mac OS X.

Do not delete the folder 'LaunchDaemons' or anything else inside, unless you know you have another type of unwanted software and more VSearch. The file is a normal part of Mac OS X. The "demon" refers to a program that starts automatically. This is not inherently bad, but the mechanism is sometimes exploited by hackers for malicious software.

If you are not sure whether a file is part of the malware, order the contents of the folder by date modified I wrote in step 2, no name. Malicious files will be grouped together. There could be more than one such group, if you attacked more than once. A file dated far in the past is not part of the malware. A folder in date dated Middle an obviously malicious cluster is almost certainly too malicious.

If the files come back after you remove the, they are replaced by others with similar names, then either you didn't start in safe mode or you do not have all the. Return to step 1 and try again.

Step 4

Reset the home page in each of your browsers, if it has been modified. In Safari, first load the desired home page, then select

▹ Safari preferences... ▹ General

and click on

Set on the current Page

If you use Firefox or Chrome web browser, remove the extensions or add-ons that you don't know that you need. When in doubt, remove all of them.

The malware is now permanently inactivated, as long as you reinstall it never. A few small files will be left behind, but they have no effect, and trying to find all them is more trouble that it's worth.

Step 5

The malware lets the web proxy discovery in the network settings. If you know that the setting was already enabled for a legitimate reason, you can skip this step. Otherwise, you must disable the setting.

Open the network pane in system preferences. If there is a padlock icon in the lower left corner of the window, click it and authenticate to unlock the settings. Click the Advanced button, and then select Proxies in the sheet that drops down. Uncheck that Auto Discovery Proxy if it is checked. Click OK, then apply, then close the window.

Step 6

This step is optional. Open the users and groups in the system preferences and click on the lock icon to unlock the settings. In the list of users, there may be one or more with random names that have been added by the malware. You can remove these users. If you are unsure if a user is legitimate or not, do not delete it.
