What Does The Best Antivirus For Windows Stand For?

Despite what you might think, being the most popular PC operating system in the world - Windows  - isn’t easy. Its users make an appealing target to all sorts of illegal, immoral, and/or simply nosey practices, including malware, spying, ransomware, financial frauds, identity theft, and more.

And to make it worse, it's not easy to choose the right antivirus software for your Windows device. You have to make sure that you do enough research before making your choice. These are the most important factors to consider:

  • Scanning And Detection Methods - You have to make sure that the antivirus software offers real-time scanners and on-demand discovery
  • Payment Terms - The majority of antivirus software companies offer a yearly subscription for their services. Keep a lookout for how different antivirus software prices are
  • Effect On The Speed Of Your Device - The best antivirus software will not affect the speed of the device. If the antivirus affects the speed of your device, it could be a problem
  • Privacy Policy - We live in a time when personal information is under a great threat. You need to make sure the company selling the software has not been caught in a privacy scandal
  • Ease of Virus Removal - It should easily remove malware, so you need to look into what method the software uses to remove a piece of malware from your devices 
  • Tech Support - Good antivirus solutions will offer amazing tech support. Make sure that the software you choose has a good rating when it comes to customer service and tech support.

How To Choose The Right Antivirus For Your Windows Device?

Choosing the right antivirus for your device can be hard, we know.  There are so many options on the market that you may not know which to choose. You know that you need an antivirus, but do you know which criteria it should meet?

Look for all-inclusive protection. A good security product must include several security layers that protect you against modern cyber threats like:

  • Viruses
  • Trojans
  • Worms
  • Spyware
  • Rootkits
  • Ransomware
  • Adware
  • Network attacks 
  • Web threats

Each security product has its ups and downs. A security product can be the right one for you as a beginner, while another might be the right one for you as an advanced technical user.

It's important to keep your personal needs and user-behavior in mind when choosing your antivirus solution for Windows.

How Does Antivirus Software Help Protect Your Windows Device?

One of the aspects that define viruses and malware is that they’re often disguised as totally harmless files. They may look like simple installation files for a useful tool or even friendly URLs while you’re browsing the web.

This is how most malware, spyware, ransomware, and general viruses infect your PC.

Once you’ve downloaded or clicked on them, the files will quietly install malicious programs across your device and start wreaking havoc, often long before you even realize it. By the time you do, it’s too late.

Antivirus software stands between your device and the harmful files, websites, and content online by acting as a fine sieve.

Instead of letting any file enter your device, it will scan files and folders you download, explore every bit of data on your hard drive, and actively delete and quarantine any malicious programs it finds.

Additionally, it includes a range of scanners, firewalls, and other privacy protections that stop attacks before they ever reach your device. More impressively, most antivirus software today does all this in real-time.

By creating preventive defenses in addition to having fast reactions when something slips through, the software lets you maintain your online freedom and browse safer.

Windows Security

What Extra Measures Can You Take To Secure Your Windows Device?

Antiviruses today can handle a significant amount of your computer’s defenses, but they’re not silver bullets that will protect against every and any threat. Part of keeping your devices safe is following the best security practices you can take to significantly reduce your exposure to possible attacks.

Here are some ways you can improve your security and bolster your PC defenses:

  • Secure passwords
  • Keep windows software up to date
  • Use VPN
  • Use Encrypted Messaging Apps

Use Secure Passwords

One of the biggest ways hackers and others gain access to your device isn’t through some sophisticated hacking method, but rather by finding out your password.

There are various mechanisms hackers use—from social engineering attacks that simply ask you for it to brute force attacks that break your password—but they all result in giving unfettered access to your device.

One way you can avoid this is by strengthening the type of passwords you use. Instead of keeping it to basic words or familiar dates, you should attempt to include random numbers and letters, and even words that aren’t related to anything. Mixing in different cases and even symbols also help.

Keep Your Windows Software Up to Date

Many attacks are successful because they prey on a combination of user negligence and unfixed vulnerabilities. Most software includes some unexpected errors and security gaps, but it is constantly updated and patched to prevent attacks and breaches.

However, if you’re not careful, or don’t update your Windows software frequently enough, you leave those vulnerabilities exposed, and therefore also your device.

Windows offers excellent updates, and you should always keep on top to make sure you’re using the most current versions, which keeps you secure from the newest attacks.

Use a VPN When Browsing

Although VPNs have become synonymous with accessing streaming services and break geo-restrictions, they’re incredibly useful when it comes to protecting your privacy and your data online.

When you browse the web, you leave a trail everywhere you go, and you expose your device and private data when navigating unsafe areas of the web. This opens you up to attacks and data theft and exposes your Windows devices to further infiltration and infection.

A VPN helps you eliminate the trail by anonymizing your browsing and masking your IP address, but it also gives you tools to protect your data while it’s being broadcast, preventing hackers from ever looking at it.

Use Encrypted Messaging Apps

Today, security is about more than viruses and malware. It includes keeping your data, and even your private communications, safe from prying eyes and malicious actors.

There are multiple messaging applications that don’t encrypt your data, leaving it exposed while it’s being transmitted between users and opening it up to attacks.

These apps may seem fun or easy, but they’re surprisingly harmful to your devices. Instead, look for messaging tools that both encrypt your data on your servers and while it’s being transmitted.

This will help you avoid prying eyes and peeping toms who could glean important information about you and use it to attack your devices and identity.
