Which foreign free security software can protect our PC?

We can use free software to protect computers, but there are some precautions. Generally, the free security software is not as easy to operate as expensive condoms. Of course, it is unlikely to be fully protected, and there are no features that users may not need, such as anti-spam and children's Internet protection. All of these companies that provide free security software have more powerful paid products that provide better support and more functions.

On the other hand, free software uses less computer resources and does not speed up computer operation like a pay-as-you-go condom.

So what should I pay attention to when using free software? First, a good firewall (not suitable for Windows systems) and real-time anti-virus protection software (in fact, this name is somewhat misleading to users, because the current versions of these software can defend against various types of malware, instead of virus ). It is better to deploy another anti-malware software without the need to run it in real time.

You can try to use the Comodo firewall software. The firewall often exceeded those paid firewalls in independent tests. However, it is not a simple firewall. Only people who know the various technical settings can use it freely.

Comodo has recently added anti-virus software to make it the first free condom, but there is no independent test for Comodo anti-virus software, so it is not necessarily reliable. When installing Comodo in that year, it is best to cancel the anti-virus software option, as long as the firewall is installed.

This means you need to deploy different anti-virus software. You can try Avast, a free anti-virus software, and get a good result in the last round of AV-Comparitive testing.

In addition, we provide two additional protection software, which is worth trying. SuperAntiSpyware and Malwarebytes use either of the two antivirus software to scan the computer disk every week, to ensure system security and stability.
