What Is A Computer Virus

Computer viruses are so-called because, like real viruses, they can self-replicate. Once your computer is infected with a virus, this is how it spreads. When a computer virus infects your computer, it may slow it down and stops it working properly.

Another way your computer become infected with a virus is through a download from the internet.

The third way your computer could become infected with a virus is if you open an attachment, or click on a link, in a spam email.
Can Your Computer Become Infected With A Virus Via Email
Your computer can become infected with a virus via email, but only if you open attachments within a spam email or click on the links contained in them.
Simply receiving a spam email will not infect your computer. Just mark these as spam or junk and ensure they are deleted. Most email providers will automate this but if any slip through the net, just mark them as spam yourself and dont open them.
