As mentioned by
@Umbra , for some security products, "Security Suite" is just equivalent to "Antivirus + Firewall + Some features you will not need".
But there are also some exceptions. For example,
- For Kaspersky, the Internet Security Suite has Application Control, which can adjust the privilege of programs in a fine-grained manner, and Trusted Application Mode, which not only can block unknown EXE, but also can block unknown DLLs. As far as I know, these useful features are not available in the Antivirus version of Kaspersky.
For some other products, there is nearly no difference in terms of protection between the antivirus version and the internet security version. For example:
- Avira. Its Internet Security Suite = Antivirus + System Speed-up. The latter one is just a independent cleaning/optimization tool.
- McAfee. Its Antivirus Plus version actually contains a firewall. The only differences between its Antivirus Plus version and Internet Security version are just Anti-spam and Parent Control.
- WebRoot. Similar to McAfee, its network connection monitor module has been contained in its antivirus version.
Most antivirus vendors will give a table on their websites, which lists the differences between their antivirus and security suit. It can help you to make a decision between the antivirus version and the security suite version.
