Use an anti-malware app - Installing an anti-malware app and keeping it up to date can help defend your PC against viruses and other malware (malicious software).

Microsoft Defender is free anti-malware software included with Windows, and it's kept updated automatically through Windows Update. There are also anti-malware products made by other companies that you can choose from.

Use a pop-up blocker with your internet browser - Pop-up windows are small browser windows that appear on top of the website you're viewing. Although most are created by advertisers, they can also contain malicious or unsafe code. A pop-up blocker can prevent some or all of these windows from appearing. The pop-up blocker in Microsoft Edge is turned on by default.

Make sure that Tamper Protection is turned on - In Windows 10 and 11 we have a feature called Tamper Protection that prevents unauthorized apps from changing your security settings. Many viruses and malware try to disable anti-malware software or other security settings when they're installed in order to evade detection. See Prevent changes to security settings with Tamper Protection for information on how to confirm that it's turned on.

Yes. There are antivirus programs that are 100% free.

If you have a wifi router, you likely already have a measure of protection from intrusion in the form of a built-in hardware firewall. Additionally, you may have a software firewall built into your operating system, such as Windows Defender for Windows users. According to the AV Test Security Report 2017/2018, Windows is by far the most attacked operating system, so built-in protection makes sense.

TIP: Good antivirus software will include a firewall as part of a wider range of security features. Take a look at our round ups of the best overall antivirus and best antivirus software for Mac.

The software will add an extra layer of protection to your connections when you connect to public wifi hotspots and it assesses the security of your home wifi network to improve protection from attacks. It updates itself automatically, so you benefit from an up-to-date threat protection database.

The firewall will block incoming connection requests and it includes other security measures. These include the ability to select which applications on your computer are allowed to connect to the internet and a security level feature. The software monitors activity in the registry and blocks alterations. This is a very important protection measure against worms and persistent malware.

As well as blocking incoming connections, this software package will monitor your computer for ongoing threats, with a constantly updated threat database. The monitor alerts you in real-time to detected risks. You get a Sandbox environment for any new software you download to protect from hidden viruses. The system uses AI to build up a profile of normal operating behavior on your computer so that it can block suspicious activity. You can choose to block specific applications from accessing the internet while the software monitors all outgoing traffic as well as inbound data.

As well as being a firewall, this utility is a host-based intrusion detection system. It examines the log files on your computer to look for worrying events. It will also protect those log files from unauthorized alteration or deletion, which is a track-covering trick that some malware uses.

Popular operating systems often come with their own software firewall, such as Windows Defender in newer versions of Windows. However, this is a rudimentary firewall that could do with a lot more options, which you get with third-party firewalls.

Protect all the computers in your home with the Sophos Home Premium, available with a free 30-day trial (no credit card required). The same antivirus, malware protection, and web filtering technology trusted by hundreds of thousands of businesses is now yours to take home.

One way of protecting yourself is, of course, through the use of antivirus program. An antivirus can detect a problem and quarantine the file which is attempting to infect your system. However, antivirus programs can't catch everything, and they don't monitor your network connection for unauthorized attempts to access your computer.

That is the job of firewall software. When combined with an antivirus program, firewall software can provide excellent protect against a wide range of threats. Let's take a look at three best free firewall programs which will help you protect your Windows 7 PC.

Comodo has long been considered one of the best free firewall tools available. Comodo is now a full Internet security company providing many for-pay solutions, but they still provide a comprehensive free Internet security suite (with firewall) which has been given a five-star rating from CNET. Comodo technically includes an antvirus and a firewall, and the antivirus is quite good. Of course, it is up to you if you want to actually keep the antivirus protection active or you choose to just use the firewall.

Comodo has many advanced features which can help protect your computer if malware does become active on the system. This includes the ability to lock down specific files and registry keys. Comodo also has received praise for being relatively light on system resources, which is commendable for any free product. This makes it the best free firewall for computers which are older and sometimes struggle running firewall programs.

PC Tools Firewall will ask to install Spyware Doctor, a free anti-malware program. Spyware Doctor is not a third party program but rather another program made by PC Tools. It is competent, but the free version isn't a replacement for antivirus software. Overall, PC Tools is a great choice for users who have been confused by firewall interfaces in the past.

ZoneAlarm was one of the first free firewalls available for Windows computers. It has a long history of providing great protection against numerous types of threats. While the basic functions of ZoneAlarm remain the same as ever, ZoneAlarm has been refined significantly over the years.

The free version of ZoneAlarm has many advanced features, such as automatic Wi-FI security, anti-phishing protection, and behavioral threat detection. Many of these extra features are not really the responsibility of a firewall, but it is always nice to have extra protection. The core firewall features of ZoneAlarm Free remain strong, prompting a five-star review from CNET. The outbound protection is cited as being particularly strong. Outbound protection helps ensure that malware attempting to relay data from your computer to another computer will not be allowed to function

Organizations want to ensure that devices accessing their resources are secured, so they may require you to use Microsoft Defender Antivirus and additional Windows Security features. Microsoft Defender Antivirus is an antivirus software that's included in Windows and can help protect your device from viruses, malware, and other threats.

Make sure the firewall is enabled before you go online. You can also purchase a hardware firewall from companies such as Cisco, Sophos or Fortinet, depending on your broadband router, which also has a built-in firewall that protects your network. If you have a larger business, you can purchase an additional business networking firewall.
