Once installed on an antivirus software computer, you should scan the entire computer periodically.

• Automatic scanning - Depending on the software you choose, you can configure it to automatically scan specific files or folders and remind you to set the time interval to perform the scan mode.
• Manual scanning - You should manually scan files that you receive from an external source before opening them. These include:
  • Save and scan email attachments or download data from the website before opening them.
  • Scan floppy disks, CDs, and DVDs before opening any files.

What happens if the software finds a virus?

Each software package has its own way of dealing with viruses. Processing methods may vary depending on the software that determines the virus during automatic or manual scanning. Sometimes the software provides a warning dialog to let you know that a virus has been found and ask if you want to "clean" the file (remove the virus). In some cases, antivirus software may try to remove the virus without asking you. When choosing a software package, you must fully understand the features to know what it meets for you.

Which software should you use?

There are many well-known companies in providing antivirus software. Deciding which software to choose can be confusing. All antivirus software performs the same function so your decision should only focus on specific features, price and market popularity.

• What to do if your computer has a virus?

Install any software, don't be too concerned about the software package you choose, but mainly increase the level of protection. Be careful with emails introducing antivirus software. Many recent viruses come from a fake email from your ISP's technical support office, including an attachment that introduces antivirus software. In this case the attachment itself is a virus, so it can be infected if you open it.

How to get timely virus information?

This process may vary slightly depending on the software product you choose, so you need to find out which antivirus software is needed. Many antivirus software packages have the option to automatically update newly generated viruses. Therefore new news is updated regularly. This is a good solution that you should take advantage of from this option. Don't trust the emails that claim that some well-known anti-virus software company has detected 'the most dangerous virus in history' and the virus will destroy your hard drive. These emails are all scams and tricks. You can confirm the virus information through an antivirus software vendor or through sources provided by other vendors.

Installing an antivirus software is one of the simplest and most effective ways to protect your computer. But after all, the software has its limitations. Because it depends on the detection of new viruses that arise, antivirus software may not have solutions to fight new viruses. And when the provider has a solution to upgrade the software, you probably already have the virus during that time. So you also have to protect yourself by learning to use the computer safely.
