Virus Removal Process For Various Viruses
Computer viruses are the worst nightmares to a computer. They can cause all sorts of damage to computers including loss of data, destroying programs or even endangering sensitive information. These reasons validate the need for virus removal. This exercise can restore the computer to its original state. Removing viruses is usually dependent on the kind of virus on the computer.
There are various types of viruses namely; resident, direct action, overwrite, boot sector, directory, polymorphic and companion viruses among others. Resident viruses normally establish a permanent home in the Random Access memory (RAM). Here, they interfere with all the operations of the system. Its effects usually rear themselves through renamed programs, corrupt files, opened, copied or closed programs. Examples include Randex, Meve, MrKlunky and CMJ.
Boot sector viruses usually focus their activities in the boot section of the hard disk or floppy disk. This hampers the ability of this part to start the computer. On the other hand, direct action viruses work by replicating themselves upon execution. It infects the directory files and the folders when the conditions are perfect.
With overwrite viruses, various information keep disappearing because the virus deletes them. Computers users cannot use these files upon their infection, which requires their complete deletion. Examples of overwrite viruses include Trivial.88.D and Way. Polymorphic viruses like Marbug and Elkern have a unique way of operating. They encode themselves in unique way via encryption keys and algorithms. This presents an arduous task to anti-viruses because they come in different copies.
The process of eradicating a virus is child’s play provided that people are at par with the process. It is also important to avoid unnecessary panic and determine whether the computer has a virus. The first instinct is to enlist the help of anti-malware software. The software should be able to eradicate the virus or even detect it at the earliest instance. Computer users can invest in software or download them from the internet.
After successfully removing the malware, the anti-virus will send a notification detailing the same. This requires that users must shut down their PCs and reboot them. As a safety measure, they should rerun the software-if it comes back with positive results, then all is well. When the results are contrary to expectations, there is need to repeat the malware removal process.
As aforementioned, the polymorphic virus will complicate matters for the anti-malware software. This necessitates the need to start the computer via safe mode. This prevents windows registry from facilitating the activities of the virus. When infected, it notifies the virus upon the loading of the operating system. Operating the computer in safe mode prevents windows registry from performing this function.
Safe mode also allows the anti-virus software to work uninterrupted. This is because it only uses the essential components of the operating system. It might just happen that the anti-malware will eradicate the virus. If it does not, there is need for additional research. Computer users can visit internet security sites for information about the various files that house particular viruses.
The sites also detail the usual locations of these files in a computer. This allows computer users to delete these files before rebooting their computers. One thing to remember is to create backup copies of all the essential files. Deleting important files may hamper the efficient operations of the computer. Thereafter, they can run their anti-viruses again-hopefully, this will remove all the malware.
Apart from anti-viruses, it could be necessary to format the computer. Provided that users have created backup copies of their essential data, formatting will refresh the computer and sweep away the harmful elements. It is important to prevent rather than cure the computer of viruses. Nevertheless, there is no use crying over spilt milk; through virus removal strategies, users can nurse their computers back to health.
