Trojan Virus Removal on Mac

Those owning a Mac are comparatively luckier because Mac comes with an in-built protection system against virus and malware. However, you never know when infections occur in your system, and affect its performance. Till date, the only Trojan virus that is known to affect Macintosh computers is the OSX.RSPlug.A Trojan Horse which causes severe damage to your Mac. Unlike other virus though, it doesn't spread itself, but is still infectious. So, let's rewind, and figure out how did your system get infected. You must've recently browsed through some, mmm... cool (or hot?) pictures of Megax Fox, and wished to download them. You didn't really care about the source, and simply clicked on the 'download picture' tab, little knowing that it could invite a virus, that too a Trojan Horse. Result? You did get the picture, but at stake of your computer system. (That does not mean every Megan Fox picture is going to have a Trojan with it!)

The OSX.RSPlug.A Trojan Horse doesn't replicate or self-propagate itself, but can prove to be highly malicious to your system, if you do not take an action against it. For this purpose, here's a simple method of Trojan removal on Macintosh computer systems, easy to understand and easier to follow. Take a look.

How to Remove a Trojan Virus on Mac

The OSX.RSPlug.A Trojan virus has been recently distributed by a video which, when downloaded, pops out a message saying the user doesn't have the appropriate 'codec' to view it. Hence, the users, in hope to be offered the 'codec' to download the video, followed the instructions, and installed the codec thereafter, little knowing that giving the administrator password would draw in the Trojan as well. This Trojan virus, after it is downloaded into the system, is known to change all the DNS information, re-routing all your web-traffic to porn websites. However, if you tackle this malware, it will change your system's DNS information back to original, and your Mac will no more be infected. In order to get acquainted with how to remove a Trojan Horse virus on Mac, follow the steps given below:

• If you've tried updating your existing antivirus software, and found no relief, you might as well try this method out. Go to your Library folder, and click on the Hard Drive icon in the Finder section.
• Select Library Folder, and route to Internet Plug-Ins folder.
• You need to search for the plugins.settings file in the Internet Plug-ins folder. Note that, if you do not find this file there, there is no Trojan Horse virus in your system, and your system is slow due to other reasons.
• As soon as you find the plugins.settings file, click on the Trash icon, and select Empty Trash. Emptying your Trash will remove the tool that sets the rogue DNS information.
• Now, you need to pay attention to the code that you are supposed to type. Go to Applications after emptying your trash, and select Utilities. Click on Terminal after that.
• When you see a notepad like thing, type in sudo crontab -l (It's the letter L, not I). Click on Return, and enter your admin password.
• Now, take account of the response the system gives. If your system is infected, the code that would come up is crontab: no crontab for root. If this isn't the code, and something else pops up, there's no Trojan Horse in your Mac.
• If you receive the code, type in sudo crontab -r, thereby, entering the admin password. It will eradicate the job that transforms your system's DNS information. To confirm whether what you have typed is working, you could type sudo crontab -1. The response would be the code crontab: no crontab for root. If this isn't the response, the process wasn't a success.
• Last but not the least, click on exit and restart your computer. The Trojan Horse is removed from your Mac, for free.

Removing a Trojan on Mac can be a difficult task, if you are not too much into the technicalities of your system. However, if you pay attention to the codes, and follow the steps as they are, within a matter of minutes you can get rid of this malicious malware. As a last piece of advice, I would like to state that it is always recommended you do not download files which do not belong to trusted sources. Sources that are legitimate would, in most cases, never require your administrator password. However, even if you get infected by a Trojan Horse, unintentionally, you now know how to go about removing it for free, don't you?
