I've had good luck with their products as well as those by GFI Software. I currently use Vipre Internet Security by GFI. I got involved in them via the original Sunbelt Software whom I had done some beta testing for. They wrote the original engine behind Microsoft's Windows Defender and System Essentials through their purchase of Giant Software.

The other founder Stu Stauerman has gone on to found an new security company called Knowbe4 -

I had the opportunity to speak to both of these guys on the phone way way back in 2000 after I had some questions and recommendations on a product I had purchased from them. We spoke for some time about technical stuff, and when their new Sunbelt CounterSpy came out, I was asked to be a beta tester and joined the testing team. This product eventually lead on to Vipre Internet Security after they purchased Kerio Firewall. After using CS for some years, I beta tested Vipre and have stayed with them since. I can't beat their subscription price of $60.00 for a whole household of PCs. For me that's over 10 machines ranging from various desktops and some laptops. The cost savings for the site license for home users is outstanding. The regular subscription price isn't bad either at $20.00 per year, after the intial purchse. At prices like this, it's inexcusable that people do not have some kind of virus protection on their systems.
Prior to using Vipre, I was using Trend Micro PCcillin. This was long before they had the firewall and antispyware modules added. This is how I got involved with GFI or Sunbelt. We had used Trend Micro's old NeatSuite for our antivirus where I worked. This was an upgrade/replacement of the old Norton Antivirus that Polaroid was using. When my old division was sold, we had to build our own infrastructure and we were asked what we wanted. My choice was anything but Norton, and we purchased the Trend product. What is nice about Trend Micro's products is the same underlying scan engine is used across all products, meaning only one pattern update is needed and disbursed rather than needing to do multiple downloads to various systems. The underlying scan engine is the same too as that used in their personal PC products. I had to call them once for tech support one day I and asked about a personal product because I was trying to get away from Norton at home. I ended up getting a free license for 1 year from Trend, and used their products right up to three years ago.
Speaking about support, I found both companies to have outstanding customer support. Sunbelt is based in Key Largo, Florida and has a real support staff, meaning you can call them. They charge nothing for their support and will help resolve your issues. I submitted a ticket with them recently regarding a firewall issue. I received an email directly from the support the support guy. Trend has their US office in California, and their support staff was excellent when I had called them years ago. Both of these companies are far above McAfee (barf) and Symantec when it comes to products and support.
