How to check for viruses
If you think your computer or device may contain viruses, or you want to keep them running smoothly, scanning for viruses is easy. How you test for viruses depends on the software and device you have, so we’ll go through everything you need to know to run a scan effectively and keep your computer, phone, and tablet in tip-top shape.
Do you need a virus scan?
First, let’s cover some of the signs that your device may have a virus. Is your computer or device slow or difficult to boot? Have you noticed a missing file or lack of storage space? Did you notice emails or messages from your account that you didn’t write? Perhaps you noticed a change in your browser homepage or settings? Or you may see an unexpected pop-up window, or you may encounter crashes and other program errors. An example of all these symptoms is that you may have a virus, but don’t worry too much, because many of these problems can be solved with a virus scan.
What does a virus scan do?
Each antivirus program works a little differently, but in general the software will look for known malware that meets a specific set of features. It can also look for variants of these known threats that have a similar code base Some antivirus software even check for suspicious behavior. If the software comes across a malicious program or piece of code, it removes it. In some cases, a malicious program may be replaced with a cleaner from the manufacturer.
How to check for viruses
The virus testing process depends on the type of device and its operating system. Here are some tips to help you scan your computer, phone and tablet
On a Windows computer
If you’re using Windows 10, go to “Settings” and look for the “Updates and Security” tab. From there you can detect the “Scan Now” button.
Of course, many people have invested in more powerful antivirus software that has a higher accuracy rate and drains less of their system resources such as McAfee Total Protection. To learn how to perform a virus scan using your specific antivirus software, search the software’s help menu or look online for instructions.
On a Mac computer
Mac computers do not have a built-in antivirus program, so you need to download security software to scan for viruses. There are some free antivirus applications available online, but we recommend investing in trusted software that can protect you from various threats. Downloading free software and scanning for free viruses online can be risky, as cybercriminals know it’s a good way to spread malware.
Whichever program you choose, follow their step-by-step instructions on scanning for viruses, either by searching under “Help” or by searching for it on their website.
On smartphones and tablets
Yes, you can get a virus on your phone or tablet, although they are less common than computers. However, the wide range of mobile malware is growing, and if you download a risky app, click on an attachment in a text message, go to a dangerous webpage, or connect to another device that contains malware, your device may become infected.
Fortunately, you can protect your device with mobile security software. It is not usually installed, so you need to download an application and follow the instructions.
Since the Android platform is an open source operating system, there are a number of antivirus products for Android devices that allow you to scan for viruses.
Apple devices are a little different, because they have a closed operating system that does not allow third parties to see their code. Although Apple has taken other security precautions to reduce the risk of malware, such as allowing apps to be installed only from Apple’s official App Store, these measures are not the same as antivirus programs.
For even stronger security on your Apple device, you can install mobile security software to protect personal data such as contacts, photos and messages stored on your phone or tablet.
All-in-one protection:
If securing all your computers and devices individually seems irresistible, you can choose a comprehensive security product that protects computers, smartphones and tablets from a central control center, turning virus resistance into a breeze.
Why is a virus scan so important?
Every day new online threats appear, putting our personal information, money and devices at risk. In the first quarter of 2019 alone, McAfee identified 504 new threats every minute, as cybercriminals applied new tactics. That’s why it’s important to keep all of your sensitive information secure, as well as to stay away from these threats by constantly using surveillance and testing security software for newly identified threats. Virus scans are an essential part of this process in detecting and removing malicious code.
How often should you run a virus scan?
Most antivirus products regularly scan your computer or device in the background, so you should start a manual scan if you notice anything suspicious, such as a crash or additional pop-up. You can schedule regular scans on your schedule.
Virus prevention
Of course, the best protection is to avoid getting infected in the first place. Here are some smart tips to get rid of viruses and other malware:
