It is important to note that a virus cannot be spread without a human action or social engineering, such as running an infected program to keep it going. Almost all viruses are attached to an executable file, which means the virus may exist on your computer, but it cannot infect your computer unless you run or open the malicious program. It is wise not to download anything that you aren’t sure who the real sender is. They can be hidden in free-trial software or other files that you download. Viruses also enter through downloads on the internet. Viruses can enter to your computer as an attachment of images or as audio or video files. A Computer Virus is more dangerous than a computer worm as it makes changes or deletes your files while worms only replicate themselves without making changes to your files and data. A virus could corrupt or delete data on your computer.
What is a Computer Virus?Ī Computer Virus is a program written to enter your computer and damage or alter your files and data.
Wherever a malware term is used it means a program which is designed to damage your computer and it could refer to either a virus, worm, or Trojan Horse. Malware is designed to cause damage to a stand-alone computer or a networked PC. Malware is short for “malicious software” and is used as a single term to refer to a virus, spyware, worm, etc.
