Pros: Simple. 3 options. Scan, settings, and history. That's it. Super easy for people that hate updating their antivirus all the time and worrying about it getting in the way and slowing down their computer. It updates by itself in the background.

Cons: None

Pros: I have used Trend-Micro since way back when. It used to be called PC-Cillin, and the icon was a medicinal capsule. It was great back then. Fully customizable, no hits on performance, etc. As time went on, and new versions came out, it became less customizable, and more of a drag on the system

Cons: When they went to Internet Security 2009, it wasn't too bad, but not as good as previous versions. Internet Security 2010 was worse, far less customizable, and took a greater toll on resources. Titanium is the worst- least customizable, hard on the system, slow to load, and does not get along with all other third party software. I also have- but stopped using Titanium Max- just horrible.

Overall Review: If they would just go back to the drawing board, and incorporate all the good stuff of the older versions, and stop trying to be everything to everybody- like some of their larger competitors, they would have a great product, a great niche in the market, and a loyal following. I liked them because of customization, no performance hits, and they played nice with other software. All gone. Fortunately, you can use the Titanium serials on the older versions, but otherwise I could not recommend it.

Pros: free after rebate

Cons: Will only update trend micro internet security? i have Trend Micro AntiVirus plus AntiSpyware and it wont update license.

Overall Review: I want a refund

Pros: Trend Micro does a good job keeping the bad guys at bay. This product will keep your computer safe from the nastys that try daily to infitrate your sanctuary - your PC.

Cons: Slows down my workstations, trys to hard to completely control my web surfing and my daily work. Becoming too bloated. Kicked my performance in the teeth.

Overall Review: As a professional IT in charge of AV for a utility company, i have come to appreciate Trend Micro and the slick way their product works in the environment which I administer on a daily basis. Easy to use, fast updates, always on top of new virus definitions when a new attack tries to make its way into the works. I am sadly disappointed in this home product. I purchased it as a renewal/upgrade, and it immediately affected the performance of my workstations at home. I removed it and went with plan next.

Pros: Good for three pc's. I got it free on black friday. Subscription/ Serial# can be used to renew older versions of Trend Micro Internet Security.

Cons: Unknown, have heard that there is some issues with the titanium line over the old line.

Overall Review: I have used Trend Micro Internet security for over two years and it is the best Internet security software I have ever used. I got the Titanium Internet Security software on black friday. Didn't need it then but got it for the coming year as my subscription was good till feb 2011. I was also looking into the Titanium maxium version for some other computers, I have four total pc's. I started hearing some issues and lack of features with the new titanium versions over the older versions. But you can use the serial#/ subscription from the Titanium version to renew the older version. I used it to renew the 2009 version of Trend Micro Internet security. So if you have the older version of trend micro internet security you can use the new version subscription but keep the older software. So don't let the bad reviews of the Titanium version keep you from buying it. Just buy it and keep your older version. I will try the titanium software on a test computer to see if there are issues.

Pros: None.

Cons: Simply doesn't work. Continuously crashes. Phone number for 24-hr tech is disconnected, and the regular tech support is only open until 6pm. I hope I can return this.
