Welcome to Class !!

We are eager to have you join us !!

In today’s Computer Science class, We will be learning about Virus Detection. We hope you enjoy the class!

 

 

An antivirus tool is an essential component of most anti-malware suites. It must identify known and previously unseen malicious files with the goal of blocking them before they can cause damage. Though tools differ in the implementation of malware-detection mechanisms, they tend to incorporate the same virus detection techniques. Familiarity with these techniques can help you understand how antivirus software works.

Antivirus software is a type of utility used for scanning and removing viruses from your computer. While many types of antivirus (or “anti-virus“) programs exist, their primary purpose is to protect computers from viruses and remove any viruses that are found.

Most antivirus programs include both automatic and manual scanning capabilities. The automatic scan may check files that are downloaded from the Internet, discs that are inserted into the computer, and files that are created by software installers. The automatic scan may also scan the entire hard drive on a regular basis. The manual scan option allows you to scan individual files or your entire system whenever you feel it is necessary.

Antivirus software identifies, prevents, and removes malware from a computer system. Malware is any number of viruses and software bits that intend to harm the computer or steal information, such as viruses, adware, rootkits, backdoors, hijackers, key loggers, spyware, trojans, and worms. Modern antivirus software employs several methods to detect and remove malware. However, no antivirus software can detect and prevent all possible malware.

 

Types of Antivirus Software

Norton AntiVirus

Norton is one of the most well-known antivirus software. One of its key features is that it updates every 5 to 15 minutes to make sure your system is up to date.
