How can we protect ourselves?
While the best way is antivirus software, operating systems already come with programs like Windows Defender and Windows Security. There are also other, free programs like Avast and Kaspersky.
They may seem simple, but they’re highly effective at destroying Trojan horses, worms and spyware. It’s also important to keep on top of updates. There are other ways to prevent viruses infecting your devices:
- Take special care on social media. Never open files without checking their source.
- Close websites when the browser tells you they’re not secure.
- Do not accept files from people you don’t know.
- Back up your files regularly.
1. Install antivirus or anti-malware software
It might seem obvious, but many home computers don’t have this protection. It’s essential to keep your PC virus free.
2. Keep your antivirus software up to date
Protective software is one thing; but keeping it up to date is another. While free antivirus software is better than nothing, it’s not the best solution. Microsoft has a free security package if you operate with Windows, even though you would’ve already paid for the Windows licence. Many people don’t know about it; but, actually, it’s a good form of protection.
3. Run antivirus scans regularly
This might also go without saying, but we often forget to do it. Adjust the settings so scans run at regular intervals (like once a week). Using the device while antivirus software is running can be challenging. Try running it at night when the computer is idle. Because we usually turn our devices off at night, we tend to overlook scans. Set the antivirus software to run on a specific night and only leave the computer on at that time. Make sure it doesn’t switch off automatically or go into hibernation mode.
4. Keep your operating system up to date
Whether you use Windows, Mac OS X, Linux or another operating system, always keep it up to date. Developers regularly release patches to plug security leaks. The patches will help keep your system safe. You should also keep your antivirus software up to date. New viruses and malware are emerging constantly. Their software scanning is as sophisticated as their databases, so make sure you’re on top of things.
5. Protect your network
Many PCs connect to files, printers and the Internet via Wi-Fi. Make sure the network requires a secure password and never browse on open networks.
Use WPA or WPA2 encryption. PME is no longer secure enough. Expert hackers can circumvent it in minutes. It’s also a good idea not to disclose the name of your Wi-Fi network (the SSID). You can connect to the network manually on your device by typing in the SSID and password. If you usually let guests use your Internet, give them an alternative SSID and password just in case.
