1. What is Internet Security Suite
Internet security suite sometimes makes ordinary home computer users confused. Is it antivirus or anti-malware? Or is it more potent than both? The second question is a good guess. Simply speaking, the Internet security suite should include the usual features of antivirus and anti-malware. Namely, the Internet security suite has the capability of antivirus. Besides, it offers more to protect from the risk of the Internet. The usual Internet security features are firewall, phishing detection, email protection, blocking key logger, etc.
If you installed antivirus products at the business level, in most cases, you have been protected by Internet security already. The business or enterprise versions of antivirus products usually integrate full information protection technology, covering all security requirements and functionalities. So for business-level products, antivirus, anti-malware, and Internet security suites are overlapped in the market. Their stresses may be different, but the core is similar.
If you are a home user, using or not using the Internet security suite may be a question. The point is running features of Internet security will cost much more resources, such as CPU and memory usage, than pure antivirus products. If your computer is older, the overall running of the whole system may slow down. Usability and performance, which are apparent disadvantages of Internet security suite, are the main reasons to block many home users from installing an Internet security suite.
Unless you have many financial transactions or extensively use banking online, you don't need to consider an Internet security suite. Of course, in this case, you need to ensure your computer is strong enough. Otherwise, for most personal purposes, an antivirus will work fine for you.
