here is your answer hope it helps

Explanation:

1: A computer virus is a software program designed to replicate itself and spread to other machines. In most cases, the program is "malicious," meaning its purpose is to cause the computer malfunction in some way. In general usage, the term "computer virus" includes all forms of "malware," or malicious software

Some computer viruses are programmed to harm your computer by damaging programs, deleting files, or reformatting the hard drive. Others simply replicate themselves or flood a network with traffic, making it impossible to perform any internet activity.

2:1. Keep your software up to date

Software makers like Microsoft and Oracle routinely update their software to fix bugs that could potentially be exploited by hackers. Oracle just released on Sunday an update to its Java software to fix a security hole hackers could have used to infect computers with malware.

The software patch came after the Department of Homeland Security sent out an advisory late last week about the security flaw recommending computer users disable the Java plug-in in their Web browsers.

2. Don’t click on links within emails

A good rule of thumb is if you don’t recognize a sender of an email, don’t click on any links within it. Microsoft says 44.8 percent of Windows virus infections happen because the computer user clicked on something.

3. Use free antivirus software

You don’t have to pay for software to protect your computer or for an annual subscription to maintain the latest virus protection. For Windows users, Microsoft Security Essentials is free. Avast is another free anti-virus program.
