Helpful Links Regarding Malware Protection

An excellent link to read is Tom Reed's Mac Malware Guide.

Also, visit The XLab FAQs and read Detecting and avoiding malware and spyware.

See these Apple articles:

  Mac OS X Snow Leopard and malware detection

  OS X Lion- Protect your Mac from malware

  OS X Mountain Lion- Protect your Mac from malware

  About file quarantine in OS X

If you require anti-virus protection Thomas Reed recommends using ClamXav. (Thank you to Thomas Reed for this recommendation.)

From user Joe Bailey comes this equally useful advice:

The facts are:

1. There is no anti-malware software that can detect 100% of the malware out there.

2. There is no anti-malware that can detect anything targeting the Mac because there

     is no Mac malware in the wild, and therefore, no "signatures" to detect.

3. The very best way to prevent the most attacks is for you as the user to be aware that

     the most successful malware attacks rely on very sophisticated social engineering

     techniques preying on human avarice, ****, and fear.

4. Internet popups saying the FBI, NSA, Microsoft, your ISP has detected malware on

    your computer is intended to entice you to install their malware thinking it is a

    protection against malware.

5. Some of the anti-malware products on the market are worse than the malware

    from which they purport to protect you.

6. Be cautious where you go on the internet.

7. Only download anything from sites you know are safe.

8. Avoid links you receive in email, always be suspicious even if you get something

    you think is from a friend, but you were not expecting.

9. If there is any question in your mind, then assume it is malware.

Also download and run Etrecheck.  Copy and paste the results into your next post. It's a diagnostic tool that was developed by one of the most respected users here in the ASC.  It can identify any other malware that might be present.

You installed the "DownLite" trojan, perhaps under a different name. Remove it as follows.

Malware is constantly changing to get around the defenses against it. The instructions in this comment are valid as of now, as far as I know. They won't necessarily be valid in the future. Anyone finding this comment a few days or more after it was posted should look for more recent discussions or start a new one.

Back up all data.

Triple-click anywhere in the line below on this page to select it:

/Library/LaunchAgents/com.vsearch.agent.plist

Right-click or control-click the line and select

          Services ▹ Reveal in Finder (or just Reveal)

from the contextual menu.* A folder should open with an item named "VSearch" selected. Drag the selected item to the Trash. You may be prompted for your administrator login password.

Repeat with each of these lines:

/Library/LaunchDaemons/com.vsearch.daemon.plist
/Library/LaunchDaemons/com.vsearch.helper.plist
/Library/LaunchDaemons/Jack.plist

Restart the computer and empty the Trash. Then delete the following items in the same way:

/Library/Application Support/VSearch
/Library/PrivilegedHelperTools/Jack
/System/Library/Frameworks/VSearch.framework
~/Library/Internet Plug-Ins/ConduitNPAPIPlugin.plugin

Some of these items may be absent, in which case you'll get a message that the file can't be found. Skip that item and go on to the next one.

From the Safari menu bar, select

          Safari ▹ Preferences... ▹ Extensions

Uninstall any extensions you don't know you need, including any that have the word "Spigot" or "Conduit" in the description. If in doubt, uninstall all extensions. Do the equivalent for the Firefox and Chrome browsers, if you use either of those.

This trojan is distributed on illegal websites that traffic in pirated movies. If you, or anyone else who uses the computer, visit such sites and follow prompts to install software, you can expect much worse to happen in the future.

You may be wondering why you didn't get a warning from Gatekeeper about installing software from an unknown developer, as you should have. The reason is that the DownLite developer has a codesigning certificate issued by Apple, which causes Gatekeeper to give the installer a pass. Apple could revoke the certificate, but as of this writing, has not done so, even though it's aware of the problem. This failure of oversight is inexcusable and has compromised both Gatekeeper and the Developer ID program. You can't rely on Gatekeeper alone to protect you from harmful software.

*If you don't see the contextual menu item, copy the selected text to the Clipboard by pressing the key combination  command-C. In the Finder, select

          Go ▹ Go to Folder...

from the menu bar and paste into the box that opens by pressing command-V. You won't see what you pasted because a line break is included. Press return.

Hi all,

I am having a very similar problem as stated above with popups and ads. Can anyone help me? Do you recommend that I download Etrecheck and run a test?

Please help!

Thank you so much.

Best,

Joe

This user tip link to description for uninstalling MacKeeper: Do not install MacKeeper

To get rid of adware go to this site, The Safe Mac - Adware Removal Guide, and download and use the Adware Removal Tool.

Ghostery is a free app that has virtually stopped all ads and all pop ups including Mac Keeper on both my Macs. It is easy to install and run. It allows you pause blocking and or whitelist a site so it has options to not always be invasive. I cannot believe how nice it is to not have a single pop up and bye bye Mac Keeper. I have not seen it since installing Ghostery. I run it on both safari and firefox. And it works on my old MacBook with Snow Leopard and the new Mac Air with Mavs.
