Check if your computer has viruses

Frequent and odd pop-up windows are red flags. Pop-ups might prompt you to visit other websites to download antivirus or other software programs, which instead may install malware. Malicious pop-ups and spam may also secretly install spyware that could hijack your browser or steal your passwords and other personal information without your knowledge. Is your homepage randomly switching to another website?

Are you unable to reset it? If so, you likely have a virus. Viruses can implement changes to your homepage and create error messages, browser errors, and shortcut files. Computer viruses can create widespread problems. If unknown programs load when you turn on your computer or another connected device, turn it off.

Have you ever received an odd email from a friend that made you suspect someone hacked into their email account? As the virus continues to multiply, it uses resources from your computer and creates more activity on your computer. As a result, your battery life is diminished. Does your computer randomly crash on you? This could be a sign that your device has been infected with a virus.

Viruses can be installed on your computer without your knowledge or consent, and can insert new, malicious code that can monitor and manipulate your online activity. Some malware may not seem serious, but it can lead to big problems.

For example, criminals could use a virus to gain access to your personal information, allowing them to commit identity theft and other types of fraud. A simpler approach is to install antivirus software from a reliable company. You can then remove existing viruses and malware using a service like Norton Power Eraser.

It will perform a scan and give you onscreen instructions. If needed, you can call Norton for technical assistance. Photo: Getty.
