How does a virus affect the system and how can it be removed?
A virus was first found and researched in the 70’s. It is a set of codes that are capable of replicating themselves and spreading through other programs by means of any transmission. It is an attack to destroy the functionalities of the system. The hackers attack in to steal information and when they become unsuccessful, the virus destroys the information. Another interesting thing about the virus is it is a wonderful undercover agent which makes its detection troublesome.
There exist three kinds of viruses,
1.Boot infectors
As the name suggests, they directly affect the booting process of the system. They remain in the system from the start until it is shut down. However, with the advanced technology, such codes are rarely found.
2.Macro viruses
These viruses run in the applications of the macro programs that help them to extend their features and functionalities. But, with the modification in the Microsoft office, these codes were taken care of.
3.File infectors
Such invective codes were designed to remain the frequently opened or used files so as to trigger their action.
Initially, the anti-virus or virus removal software did work through in keeping the system safe but even cyber criminals have found other medium to attack. They send an enticing email which when clicked downloads the virus into the system and triggers its action.
Disastrous effects of a virus
If a virus has intruded the system, first of all, it will hit the targeted file, application, software or the operating system. The efficacy of the virus to replicate deteriorates the performance and the processing of the computer. It affects the screen, display, and functionalities of the PC. It also affects the downloading and installation of other software making it difficult for the user to work on it. In some cases, users also face issues like overridden files, data loss, low memory space and slow working speed.
How to remove a virus?
If the virus has made its way into the system then, first of all, get the system in safe mode then run an anti-malware scan or virus protection software scan to detect the malicious codes and files affected by it. Delete the code and clear/ uninstall the files to eliminate any future attacks.
Once done, you can reinstall or download the deleted files from a trusted source but make sure that security features are enabled.
