Stop the Trojan Virus Warnings! - How Can I Remove trojan?

How to get a Trojan off my computer is a commonly asked question these days. But what are the basic troubleshooting and removal steps you should take to get rid of this type of virus? Specifics depend upon the actual malware you have downloaded and/or contracted; however, the basic Trojan removal process can be broken down into the following steps:

• Stop the Trojan process
• Keep it from recreating itself
• Delete all files associated with the virus

Stopping the process may be attempted while logged in normally to the computer. It's best to start up the Task Manager by pressing Ctrl-Alt-Del and looking at the Processes tab. Make sure you have checked Show processes from all users and sort by Memory. Quite often, the offending popup window will have a title and that same name will show as a process within Task Manager. Highlight said process and press the End Process tab.

Quite often, the Trojan is stubborn and will come back automatically even though you have killed the process. In this case, you should boot into Safe Mode or Safe Mode with Networking since you will need to access the internet. To do so, reboot your PC and press the F8 key a couple of times before your Windows screen appears. Choose Safe Mode with Networking and press Enter. This mode runs a bare-minimum set of drivers to allow you to log into Windows but won't allow you to run any of Windows' advanced features. The nice thing about Safe Mode is that most Trojans and viruses have a difficult time running in this reduced feature-set. If you find the malware is still popping up, run the aforementioned step to stop it.

To keep the harmful piece of spyware from recreating itself, I recommend temporarily disabling System Restore. To do so for XP: right-click My Computer, Properties, System Restore Tab and Check Turn off system restore. For Vista/7, right-click Computer, Properties, System Protection, Configure, Turn off system protection. This will keep the Trojan from seemingly recreating itself from out of thin air. Every-so-often, a piece of spyware will create a task in Task Scheduler/Scheduled Tasks. Enter your Control Panel to verify that there are no strange-looking entries. Delete ones that appear to be nonsense-named executables. When in doubt about a scheduled task, look it up online.

I recommend running a full system scan with a good malware scanner such as MalwareBytes to ensure all traces of the bug have been removed. Download a copy, install it, update the definitions, and run a full scan while still in Safe Mode. To be extra safe, reboot back into Safe Mode and run a second scan. This should remove all traces of your Trojan from your computer.

Manually removing a Trojan horse virus from your computer is no easy task. These ingenious little parasites have an uncanny way of working themselves back into your system just when you are certain they've gone for good. I recommend always having a reputable antivirus and antispyware client running on your computer. By following good web surfing habits and not visiting any shady sites, along with up-to-date definitions, you shouldn't find yourself asking how to get a Trojan off my computer.
