We have seen several lists of security programs, subdividing them by type of product: Antivirus, Antimalware, Firewall, Protection of websites, antispam, antirootkit. As explained several times, the difference between free and paid security products is not in quality but in functions, sometimes, more limited. Most paid antivirus like Nod32, Avira, G-Data, BitDefender and all the others, are not simple antivirus software but real complete security suites that protect the PC from multiple types of threats and do not need anything else. Those who use a free antivirus instead may be forced, depending on their needs, to install other software, perhaps a firewall and a malware controller.
Those who prefer all-in-one security suites (all in one) and still want to adopt free solutions, can continue reading in this article and download one of these among the best protection suites for free (before installing these programs, you must remove other antivirus from Windows).
1) Comodo Internet Security is perhaps the most famous and notable free complete security suite for pc. This program has never betrayed users and has continued to improve without asking for cash outlays. It includes, in a single installation: antivirus, anti-botnet, anti-rootkit, the most awarded firewall ever, intrusion prevention, sandbox for untrusted software, anti-malware and buffer overflow protection to provide complete protection against a multitude of threats today. Some modules of the suite can also be downloaded separately as written in the lists of the best free antivirus and the best free firewalls .
With a nice user interface, Comodo is quite easy to use and configure, suitable for everyone and highly reliable.
2) Qihoo 360 Security is the most complete free antivirus, a complete suite with anti-malware engine, phishing filters and protection from dangerous sites and protection of downloads.
What makes 360 Total Security particularly beautiful is its elegant interface, easy to navigate, pleasing to the eye and professional.
3) FortiClient is a free protection suite that includes anti-malware / antivirus, parental web control, and VPN for secure connections. It is a little-known program but with some truly unique features. The antivirus is very powerful, capable of detecting even unknown threats, in a reactive and proactive way. The free version includes, Antivirus / Antispyware engine, firewall protection, intrusion prevention, Web filtering, WAN optimization, Anti-Rootkit, Software Behavioral Analysis, real-time protection and Antispam.
4) Panda Antivirus light on resources, easy to learn and use and effective in keeping the system safe from any cyber threat, with real-time protection against malware and spyware.
5) Sophos Home is another free security program to protect home computers from threats, the free version includes antivirus and anti-spyware protection, web browser protector, online shopping protector. This antivirus is also available for Mac.
To conclude, I would like to warn you to be wary of "Security Suites" other than these or in any case not certified by specialized sites because they are often fake antiviruses that take the PC hostage.
