To remove a Trojan virus, install antivirus software with real-time protection, run a full scan, and delete any infected files. Disable suspicious programs on startup and manually locate and delete the virus. Consider downloading a separate antivirus program or restoring the operating system as a last resort.
There are several ways to get rid of a Trojan virus from an infected computer system, and any delay on your part puts your personal information at risk. Perhaps the most direct route for the average person would be to install a full antivirus program that can automatically remove the Trojan, but there will also be times when an unidentified threat goes unrecognized and will need to be removed manually. Sometimes, this can be as simple as deleting a corrupted program from the infected system via the Control Panel, but in other cases, it may be necessary to actually search for the Trojan virus and forcibly remove it from wherever it was installed.
The most effective way to get rid of a Trojan virus is to have software that can detect it in real time, i.e. as soon as it is downloaded, and an antivirus program that will stop and eliminate it. Many of the virus scanners, including free versions, offer real-time protection, but they need to be turned on; if the program icon does not appear in the lower right corner, it means that it is not currently running. If you suspect a Trojan virus or any type of malware, run a full scan on the infected computer and quarantine or delete any files found. Of course, your antivirus program is pretty much useless if it doesn’t stay fully up-to-date, so make sure you keep automatic updates turned on, and visit the manufacturer’s website often to check for newer versions.
If your antivirus program fails to get rid of a Trojan virus, it will need to be disabled automatically. On any Windows® system older than Windows 7®, select “start” then “run” and in the field box type “msconfig”. Then, click on the startup tab and browse the listed entries, looking for any name or path that doesn’t belong to a vital program. Write down each of the suspicious entries and do a web search to identify what each of them are and disable the questionable ones. For Windows 7® systems, this same service can be accessed from the control panel in the “programs” tab.
Once you have identified all suspicious programs that load on startup, note the “location” of the file and manually locate and delete it from your system. An alternative method of getting rid of a Trojan virus is to do an additional web search that contains the file name and the “removal” in the text; it’s likely that others have experienced the exact same problem, and detailed instructions could be listed on an antivirus forum or website. A final method of getting rid of a Trojan virus would be to download and install an entirely separate antivirus program, as even the best ones don’t catch 100% of the available Trojan viruses, but this method would require that the current antivirus program be uninstalled first.
Another good option would be to implement the OS restore option, but since any data created after that restore point will be lost, it’s not recommended unless absolutely necessary. When all else fails, the system can also be reformatted with a clean install of an operating system. This restores the computer to factory conditions.
