I'm not an advocate of suites. All-in-one tools and suites are filled with extra features (including "bells & whistles") which typically use more system resources than separate programs that do the same task. They tend to have varying degrees of strengths and weaknesses for each feature. In contrast, separate tools are designed, built and maintained with a greater focus in a specific area so they are generally of better quality and more effective at what they are designed to do. This means the program's performance for that particular feature is usually superior than their all-in-one counterpart. Further, all-in-one tools generally do not allow the user as much flexibility in tailoring default settings and usage.
Personally I don't have a problem with "suites", as long as they are Internet Suites. These will often offer more than a basic Antivirus protection, adding Internet related features such as a Firewall, which is always good to have (as it will most likely be more efficient than the default Windows Firewall in Vista and later versions). So as long as all the features included are directly related to the security of the system, a "protection layer" like I call it, I don't have any problems with it. It's when they start adding features like secured web browsing, Cloud storage, etc. that I find it useless. For secured web browser, Comodo have two good ones for free, or you can beef up yours easily with extensions and add-ons. For Cloud storage, there's companies specialized in that like DropBox, Box, Google Drive, Microsoft OneDrive, etc. You don't need these features included in your Antivirus product, features that you have to pay for. Secured vault on your system? TeraCrypt, VeraCrypt, TrueCrypt 7.1a, etc. can all do that as well, free of charge. I think Antivirus companies should keep the focus on what they do best : creating security software for the user, and leave the rest, the "bloated" features to companies that actually specializes in these domains.
