Computer viruses are self-executing, replicating programs written specifically to change the way a machine works, without the knowledge (or permission) of the operator/owner. They can seriously damage the machine by deleting important file and corrupting programs. So the best way to avoid viruses is to use reliable Antivirus Software.
Firewalls are to PROTECT your privacy. They keep other computers from contacting yours without your permission and sending viruses to it or accessing private information on your computer.
computer viruses, worms, Trojan horses, and rootkits
In the 21st century it is hard to live without computers so one of the best ways to stop viruses are to install anti-virus softwares into your computer regularly.
One can protect their computer hardware devices by installing a firewall in order to prevent any malicious activity to be sent to ones computer. Without a firewall one runs the risk of receiving a virus through email or even by visiting certain websites.
Removing viruses without a suitable program is not recommended. While you can remove the affected files, viruses can execute programs that go unnoticed by a user. If a user cannot purchase an antivirus program, there are free and trial options available.
1. Viruses gets inside your computer 2. Worms copy themselves inside your files without you knowing and doing something. 3. Viruses like spyware, adware, Trojan horse and other viruses that are very harmful activate when you open them. 4. Then some will destroy your registry, delete your system files, shutdown unexpectedly, and your computer suddenly goes wrong.
Viruses are quite easy to pick up when surfing the internet - some will get to you without you even knowing! Viruses can enter your PC when you download something, or when you accept an email from someone - essentially, when you knowingly accept a connection between your computer and another computer (especially if you don't trust the person/connection), there is a potential for a virus transfer to occur.
