Best Free Computer Security Software

Best Free Computer Security Software

Cybercrime is a serious and growing threat, so it’s important to have strong defenses. You can’t depend on just one antivirus program for protection; you need a layered security strategy that includes a reputable antivirus program, firewall software, and web browser extensions.

AVG AntiVirus

AVG AntiVirus is a free antivirus program that you can use to protect your computer from viruses and other malware. It’s easy to use, comes with many features and has a good reputation among users. However, it doesn’t offer as much protection as the paid version of AVG.

AVG AntiVirus uses cloud-based scanning technology to detect threats before they can do damage or infect your system. The program includes an anti-spyware feature that blocks tracking cookies from websites you visit so advertisers cannot track your online activity (which is especially useful if you browse the internet using public WiFi).

The software also blocks pop-ups before they appear in order to prevent malware infections through malicious links found on these annoying advertisements.

Avira Antivirus

Avira Antivirus is a free antivirus program that works with Windows, Mac, Android and iOS. It offers real-time protection to keep your devices safe from viruses and malware. You can use it to scan files, emails and websites for malicious content as well as USB drives before you copy any data onto them. Avira also offers an online scanner so you can check if any of your social media accounts has been hacked or compromised by hackers who might be trying to steal information like passwords or credit card numbers from people’s profiles on Facebook, Twitter or Instagram.

Bitdefender Antivirus Plus

Bitdefender Antivirus Plus is an antivirus software that protects your PC from viruses, malware and other online threats. It is compatible with Windows 7 and above. This program can be used on multiple devices so you can install it on your computer at home and then use the same license key to install Bitdefender Antivirus Plus on another device like your smartphone or tablet.

The user interface of Bitdefender Antivirus Plus is easy to use even for beginners who have never installed any security software before. The installation wizard guides you through all steps needed to get started using this product: setting up automatic updates and scans, configuring email notifications about new threats detected by Bitdefender’s Anti-Phishing module (which blocks malicious websites)

Microsoft Security Essentials

Microsoft Security Essentials is a free virus protection program that’s compatible with Windows XP, Vista and 7. It also runs on 64-bit versions of those operating systems.

It’s easy to install and use: just download it from Microsoft’s website and run the installer file (it will automatically detect which version of Windows you’re running). The software can be configured via a simple interface where you choose whether or not to automatically update when new updates are available online (you should), what type of alerts you want displayed in your system tray while working on your computer (you shouldn’t), whether or not real-time protection should be enabled at all times–and so on.

Microsoft Security Essentials works well alongside other antivirus software such as Avast! or AVG AntiVirus Free Edition; however there have been some reports that certain programs may conflict with MSE while running in Windows XP mode under Windows 7 32 bit editions. To avoid these conflicts simply uninstall any third party security suites before installing Microsoft Security Essentials if possible so that no conflicts arise between them later down the road!

ZoneAlarm PRO Antivirus + Firewall

ZoneAlarm PRO Antivirus + Firewall is a free personal security service that protects your computer against malware, viruses, spyware and other threats. It also provides protection against phishing and identity theft by blocking unwanted email messages, instant messages and pop-ups.

ZoneAlarm Security Suite offers users an additional layer of protection with anti-virus and firewall technologies that guard against malicious attacks on home computers. The suite comes with ZoneAlarm Pro Antivirus + Firewall which includes two-way firewall technology to protect against intrusions from hackers or unauthorized users trying to gain access into your system through the Internet connection; it also features anti-spyware technology which stops spammers from sending out unsolicited emails; finally there’s also a pop-up blocker component that prevents annoying advertisements from appearing on websites (you can turn this feature off if desired).

Kaspersky Internet Security (2015)

Kaspersky Internet Security (2015) is a free antivirus program that protects you against malware, cybercriminals and hackers. It has a firewall, anti-spyware and anti-rootkit protection as well as parental controls and a password manager to keep your personal data safe from unwanted access.
