What are the ways to properly remove a computer virus?

A computer virus is a particular type of program capable of replicating itself and harming a computer. It can spread from one computer to another. It can cause a variety of problems which can be a mild system slowdown or a widespread network failure. As such, it has to be eliminated. It is important to know how to properly remove a computer virus.

There are a number of ways to remove a computer virus. One of which is to use virus detection and removal software. Another way is to remove the infected hard disk to be scanned and “treated” using a different computer. Reformatting the infected disk can also be an option—wiping out everything a hard disk contains. Moreover, having the hard disk scanned by an online or cloud-based virus scanner and remover can also be an alternative solution. For more critical cases, a trip to a computer repair shop might be necessary.

Scanning and removing computer viruses with an antivirus software is the most convenient first option in dealing with virus problems. There are several free antivirus software available. They can be downloaded, installed, run, and updated without having to pay for any charge. This option, however, may not guarantee effective virus removal especially if a virus has already corrupted the system. A computer virus may even prevent the installation of an antivirus software.

Nevertheless, a virus scan and removal procedure can be more successfully undertaken if the antivirus used is not dependent on the infected computer. This means using an antivirus installed in another computer. This means taking the infected hard disk out to be connected to another computer for the “treatment.” It’s also possible to network the infected computer with an antivirus-protected computer to allow the other (protected) computer to access the infected disk without having to take the disk out of the case.

If a virus is not effectively removed by running an antivirus, reformatting the hard disk and reinstalling the operating system may be in order. Reformatting erases everything that is stored on a hard disk—including the virus and system files. This option may not be very convenient for many since all the contents of a disk would have to be deleted. Creating backups for important files in this case can also be tricky as the identification of “clean” and salvageable files is not going to be an easy task.

There are also web applications or online services that scan and clean virus-infected computers. To make use of them, a computer needs to be stably connected to the Internet. No software installations or downloading will be required but there are a few drawbacks in using these web-based solutions. First, there should be reliable Internet connection as occasional disconnections during the scanning process can lead to problems. Additionally, there are privacy issues involved since the files that will be scanned would have to be exposed online. The whole process may also take longer to complete. Nevertheless, reliable online virus scanning and removal solutions do exist and they can be very helpful in addressing an infection in case a local antivirus fails.

In instances where very important files need to be protected during the virus removal process, seeking expert help might be the best option. This would mean shelling out some bucks but there can be some degree of assurance that the virus problem will be competently addressed and important files are adequately secured. Employing professional computer repair services may be unnecessary for experienced computer users but it is very useful for the majority who may think every click and key press they make would just aggravate the problem. For critical situations, paying for professional assistance definitely makes sense.

It is important to bear in mind that the different solutions to remove a computer virus require prudence and sound knowledge with the basics of computers. Likewise, before undertaking any virus removal procedure, it is necessary to ascertain that the problem is really caused by a virus. Do-it-yourself virus removal solutions are not very difficult to execute but for those who lack adequate technical savviness, using expert assistance is more advisable.
