By: Josiah Wallman
and Spencer Noble
In conclusion, there are many different viruses out

there but they are easily avoided if you think before

you click.
The Heartbleed Bug is a virus that has infected

many popular security websites. The virus allows

malicious hackers to see information that is

supposed to be secret between the customer and

the website.
Heartbleed Bug
Keep your anti virus program up to date.New viruses are being made all the time, and anti viruses are updated frequently.

Use an online scanner. Scanners will search your computer for the latest viruses. scanners won't protect you from getting a virus, but they can help find and remove viruses your computer already has.

Stop a runaway virus. If your computer is performing slowly and accessing the network more frequently than normal, you should disconnect from the Internet and network.

Manually remove viruses. Sometimes a virus must be removed manually. This is often a technical process and should only be attempted by computer users who have experience.
