A student took notes about computer viruses from two sources. Read the sources.

Source A
Computer viruses pose a great risk to people of all ages. People rely on the Internet to find much of the information they need, so it is common to be fooled by a bad link or email attachment. Some viruses are easy to spot and fix, but others can damage a computer so badly that it needs to be replaced entirely.

Source B
One of the best ways to protect against computer viruses is to use an antivirus program. These programs run whenever the computer is on. They often catch viruses the user did not even know were there. They will even give warning messages about dangerous websites and scan documents before they are downloaded.

C
Users of all ages can reduce the risk from computer viruses by using antivirus programs.
