Here are some tips to help you in choosing the best security software for your PC. 1. There are three types of security software, which includes antivirus, internet security and total security. Antivirus security is a basic security software that protects your computer from viruses and other malicious threats that can infect the computer. Internet security protects your computer from all kinds of malicious threats from the internet and also has other features like email protection, firewall protection, anti-spam feature, which restricts any spam mail or junk mail from reaching your mailbox. It also offers complete web protection, which includes browsing protection as well as anti-phishing feature, which restricts you from visiting any phisy or fraudulent website.
