OUTRAGEOUS piece of garbage. Not only is it a memory pig, it causes windows to crash. Our system was crippled while this software was installed. And I didn't isolate the problem until after the 30-day guarantee. So I'm out $50 + the many hours I spent trying to nurse my system along.
And it looks like the 2008 version has the same problems. Way to go, guys!
Trendmicro's PC-cillin is a disaster and support is non-existent. 
2007-11-26
PC-cillin 2007 blocked access to my network scanner and destroyed my "palm pilot hotsync software installation". It deleted other important files without providing a means to get them back. Furthermore, there's no way to fix these problems with PC-cillin installed. I emailed "TrendMicro Support" for help and they did email back but only to advised me to search through their support pages (which were of no help in this case). After two weeks of frustration, I finally uninstalled PC-cillin 2007. I had to use XP's "System Restore" to get my system back to where is was previously. PC-cillin might be OK if you have a very simple computer setup. But for me, PC-cillin was worse than a virus. I will never buy from "TrendMicro" again.
Stay away

A memory hog, a complicated, interfering interface and occasionally downright ineffective. I have a speedy processor and a lot of RAM, and still it slowed my computer down to a standstill. Trend-Micro did try to help, but nothing fixed the problem. Any other program is better than this. I uninstalled for good and went back to Norton, and now my computer is back to normal.
Excellent Protection at an Affordable Price! A Must-Buy!

For the 2006 year, I protected all of my computers with Symantec Norton Internet Security 2006. However, as the end of my subscription with Symantec came to an end, I noticed a favorite magazine of mine, Consumer Reports, had recently done a rating on security suites (which include anti-virus, anti-spyware, and firewall all in one convenient package).
My eyes quickly went to the top of the ratings list, and at the top of the list was this product: Trend Micro's pc-Cillin Internet Security 2007! I highly regard the reviews that Consumer Reports conducts, and can confirm their results - I love this internet security suite!
Installation was a breeze, and pc-Cillin automatically set itself up for automatic updates. Compared to what I was using before (Norton Internet Security 2006), pc-Cillin is noticeably better, as not only does it provide better protection, it does so without slowing my computers down like Norton did. Paired with Ad-Aware 2007, I have never had any nasty program, such as a virus, infect my computer!
If you're in the market for all-in-one protection for your computer, whether upgrading from separate programs or another company's internet security suite, you won't be disappointed if you purchase this! Trend Micro's pc-Cillin Internet Security 2007 provides excellent protection at an affordable price! In fact, it's cheaper than Norton and other products, AND has better protection and features! It's a must-buy!

Junk!

Purchased 3-years of PC-Cillin with my Dell desktop. Useless and non-functioning (compliments the Dell quite nicely, actually). With two years of paid coverage remaining, I deleted this nightmare of a program entirely and went with Comcast's McAfee freebie.
Buyers Beware this is a very poor product

I want to give it a zero rating but Amazon won't let me.
PC-Cillin was pre-installed on a Dell XPS Laptop I just recently purchased and it offers to protect up to 2 other computers in your home network for free for the duration of your 1yr membership. Well, 1 month, and about 10 emails to Trend Micro tech support later, I still can't get the thing installed on my 2nd computer. The additional serial numbers that came with my initial copy won't register. The first thing Trend Micro tech support told me to do was to reinstall and to download another copy. Well, buyers BEWARE when uninstalling Trend Micro using the Add/Remove funcion in Control Panel it may corrupt your drivers. I had to reformat my computer and reinstall Win XP because of it.
Also, if you ever have the misfortune of having to deal with their email tech support, your problem will be passed around constantly to different tech support agent and answers and solution will most likely be repeated...even though they didn't work the 1st or the 2nd time around. You will find yourself having to re-explain what the situation is over and over again. Trust me, Trend Micro belongs in the trash where I ended up throwing it. I will be uninstalling it from my XPS laptop just to make sure I don't have this garbage on my computer.

Do not buy this product. If you feel you must, buy it from Trend Micro website or you will not have a warranty. I bought Trend Micro Internet Security Pro 2008 from Best Buy. It would lock up during a scan. After many attempts at getting service I ask for my money back. Trend Micro said they would not refund on a store product. Best Buy would not refund an opened product. So I am out $70.00. And they are still sending emails with no solution to the problem. I have ask them to stop sending emails but they are still comming. Worse than a virus.
worked well for me

I purchased this particular package because it allows me to monitor my WIFI. That, as it turns out, is a bit cumbersome, since the monitoring window pops up frequently. However, installation was a breeze, not only for me, but both of my kids who did it on their own. Both times I received an email to let me know they had successfully installed the software. Ultimately, I think this is an excellent deal.
NO support, hard to configure

NO SUPPORT AT ALL! This company doesn't seem to be able to afford any support people! Are they even still in business? The online support page doesn't respond for DAYS and the email support just answers with automated BS. I think they are already out of business and just keep on selling their stuff until the bitter end. I got a fully legal 3PCs authorization on eBay for 2.99 plus $2 shipping. Go figure! It's definitely not worth more! Even worse than Norton, if you can believe that!
