How to avoid computer viruses when downloading files
A computer virus is a type of malware that, when executed, copies itself to another computer and interferes with normal operations on your computer. Viruses can also delete files, infect other programs, and even steal information. As computer users become more savvy, virus writers are creating new, more sophisticated viruses. So it’s more important than ever to take steps to protect your computer from viruses.
Many computer viruses are spread through email attachments. If you receive an email with an attachment from someone you don’t know, or even from someone you know but wasn’t expecting a file from them, don’t open it. viruses can also be spread through instant messaging and social networking sites. So if you receive a message with a link from someone you don’t know, don’t click on it.
Some virus writers create websites that look harmless but are actually loaded with viruses. So even if you think you’re visiting a legitimate website, you could still end up downloading a virus. To protect yourself, only download files from websites you trust.
When you download a file, your computer checks to see if the file has been digitally signed. A digital signature is like a seal of approval that says the file is safe. If the file isn’t signed, or if the signature doesn’t match the file, Windows will warn you before you open the file.
If you use a peer-to-peer file sharing program to download files, you could also end up downloading a virus. Many of these programs don’t check files for viruses before they’re downloaded, so it’s up to you to be sure the file is safe. Only download files from people you know and trust, and be sure to scan files before you open them.
You can protect your computer from viruses by using an antivirus program. Antivirus programs scan files and email attachments for viruses. They also scan websites for malicious code. And they can even block some viruses before they have a chance to run.
When you install an antivirus program, be sure to also install a firewall. A firewall helps to protect your computer from external threats, like hacker attacks.
You should also keep your operating system and other software up to date. Software updates often include security patches that can help protect your computer from new viruses.
