A computer virus is a type of malicious software designed to disrupt normal system functions. It can spread through files, emails, or downloads and hides inside programs until activated. A virus can: Slow down your system or cause frequent crashes. Corrupt, delete, or steal files and data. Record personal information like passwords or banking details. Spread to other devices through networks or drives.
A computer virus is a malicus software that enters your computer via email or downloading files. For more information visit: http://en.wikipedia.org/wiki/Computer_virus dont worry, the addres is not a virus.
A virus enters the system either by internet (email, downloads, or giving out info) or by infiltration of your computer (a flash drive, black bag job, writing the computer virus on your computer). Internet viruses are more common, as they are easier to spread.
The virus enters the host cell in the penetration phase.
No virus is alive, therefore it can not more on its' own.
A computer virus typically starts with the infection phase, where it enters a system. It then replicates itself to spread to other systems, followed by the activation phase when it executes its malicious payload. Finally, the virus may enter a dormancy phase where it remains undetected or gets removed by antivirus software.
a virus includes a script which overwrites your computers needed files. This can be your operating system, a startup file (e.g: a hive file) or many more sutem files.
Every computer could have a virus but if you use your computer carefully it can be impossible for the virus to come to your computer.
The difference between scanning a virus and removing a virus lies in the process. Scanning for a virus means checking your computer or device to detect if any malicious software is present. The antivirus program analyzes files, folders, and system areas to identify threats. Removing a virus is the next step, where the antivirus takes action to delete, quarantine, or repair infected files so the malware can no longer harm your system.
