Is it possible to remove virus manually from a computer without using any security software? This is a question that I frequently get from my customers while fixing computer infections. The answer is “Yes. It is possible. It is tricky and you need to have the right knowledge to do it, but definitely not an impossible task for a normal computer user”

Gone are the days when we could solely depend on security softwares for protecting our computer. Recent studies on this topic have proved the same. If you look at 95% incidents of reported computer infections, this is not happening on an idiot’s computer who didn’t install any software for protection. In most of the cases, the infection happened even after having installed the so called best security softwares in the market. Sometime back, I had chat with one forum member who was bragging about how he create virus to create havoc in the corporate world. I am still not sure what he claims of himself are true or not. But he made sense when he discussed about how he used to hide virus effectively from getting caught by security softwares. Technology has changed and improved a lot and so do the programmers who develop these virus and malwares. They developed new methods for avoiding detection such as running the virus related program to run like a normal windows service, loading the viral service at the time of OS booting up in stealth mode, creating virus file similar to OS file making it difficult for the security software. This makes the computer infection very hard to detect and remove. However there are manual methods by which we can remove any type of computer infection. Let it be virus, trojan, spyware, malware, rootkit etc. They can still be removed manually

How to remove virus manually from a computer?

  • Removing virus manually needs a systematic step by step approach. Most of the computer infections are programmed to remain as hidden files. So the first step is to ensure that all the hidden files are enabled including the “hidden operating system files”.
  • The next step is to remove the temporary files within which the computer infections might be hiding. These include temporary files created by OS, applications, internet files, cookies etc.
  • Then we need to check the “loading points” inside the computer and remove the infections from there. Computer infections are capable of creating problems, only if it is located inside certain locations called “loading points” inside the computer. All together there are 16 loading points inside the computer which includes windows folder, system 32 folder, drivers folder, Program files folder, registry etc. Once inside the loading point, the next job is to identify the infected file from a good file. Googling the file name is the best method to find if a file is good or bad. Care should be taken that we need to search for the infected file in all the loading points, as if you miss any location the chances of the infection coming back after a certain period is high. Some of the troubleshooting steps which are mentioned online in forums and websites are not that effective because they don’t mention all the loading points where we need to search for the infection.
  • Once the infected file is found, then you need to remove it. Deleting an infected file itself is a bit of challenge as not all file gets deleted just by pressing the delete button.

By following these steps, you should be able to delete any computer infection from a computer. These steps might look a little complicated. But with necessary guidance, anyone with basic computer knowledge should be able to remove virus with using any security software.
