MPlayer X Mac Virus!

While you may have downloaded some malware it is not a virus. Please refer to Thomas Reed's The Safe Mace at http://www.thesafemac.com/mmg/ to determine how to uninstall it.

Also DO NOT install any antivirus apps or any other such apps. Please refer to this thread on how to keep your machine in tip-top shape!

Is there a manual way to keep an iMac running quickly and efficiently? I recently started getting pop-ups that would not go away unless I closed the program I was using. How do I keep this from happening?

Although there has been a recent iWorm infection caused by various torrents from PirateBay, ClamXav has been updated to find those files that we know about, so it would appear you're OK from a malware standpoint.

Previous infections involving the legitimate MPlayerX software were caused by adware that was included in the installer, so I would look into that next.

A colleague of mine who is a recognized malware guru here in the forum has developed a simple, safe and speedy app called AdwareMedic which will identify any currently known adware for you and offer to remove it if desired.

If AdwareMedic comes up clean, then open Keychain Access (found in /Applications/Utilities/ or LaunchPad or SpotLight). Select "Keychain First Aid" from the Keychain Access menu, enter your password, select repair and click the Start button.

Meanwhile I'll see if I can track down what you downloaded.

Apple blocks these outbreaks using their "XProtect", an anti malware system that's built in to Mac OS X.

That is just a .webhistory file, which is simply a copy of a web page you visited back in July. It is not an OS X infection and since MacScan is well known for false positives it probably isn't anything. Sorry, but that wasn't the problem.

What was the supposed name MacScan gave to this Trojan.

While I agree in principle that XProtect blocks all commonly found malware that can impact OS X and it's applications, there is no known OS X malware called "MacPlayer X" so it would have to be something else. Also, XProtect is totally ineffective against all but one form of adware (OSX.FkCodec.i).

No, it would have given it a specific name from one of 38 types of Trojan Horses shown here and multiple varieties. Another bad thing about MacScan is that it doesn't keep a log, so you can't go back and find out anything. I would just assume it was a false alarm and if you trashed what it found then don't worry about it.
