Answer 1

Here are some signs that suggest a virus might have infected your computer:

Your computer runs slowly and struggles to open files or load pages.

Messages pop up on your screen at random.

Programs start on their own, without a command from you.

Strange icons appear on your desktop.

You can hear your hard disk working extra hard.

If your computer exhibits any of these symptoms, it’s important to check for a virus right away and remove it as soon as possible. Viruses copy themselves and can corrupt your system or destroy your data. These malware programs infect devices through links in emails, web sites and pop-up windows.

There’s no need to wait until you notice the signs of a virus. There are antivirus programs that routinely scan for malicious software on your device.

Answer 2

Answer:

A computer virus is a small software program that spreads from one computer to another and interferes with computer operation. A computer virus might corrupt or delete data on a computer, use an email program to spread the virus to other computers, or even delete everything on the hard disk.
