My 2 year old computer has been progressively getting slower. For months, I tried free anti-virus software with limited success - some worked for a short while, then the slowness resumed; or the improvement was so negligible that I wasn't sure anything did improve. Although I tried Stopzilla in the past, I resisted purchasing it again thinking that $20 is too much for what I can get for free. One day, when my computer become impossibly slow, I purchased Stopzilla with the thought that if it didn't do anything, I'd take advantage of the money-back guarantee. I'm so very glad I tried! The installation was super fast, the program is very easy to use, and after 10 minutes and a computer re-boot, my PC is about 2.5 times faster than before. I am just kicking myself for wasting my time for so long waiting for pages to download just to save 20 measly dollars. Sometimes when you think you save, you actually lose.

STOPZILLA IS THE BEST COMPUTER SYSTEM THERE IS FOR PROTECTING YOUR COMPUTER. THE MONTHLY UPDATES ARE FREE AND GREAT.

I purchased Stopzilla in 2006 and when MS IE7 hit the market, the software would not work. I un-installed it and let them know via phone that I had stop using the software. They still billed my credit card for the renewal price each year. I missed it in 2007 but caught it in 2008. I called them and credited my card for the $39.95 charged in 2008 but refused to give me credit in 2007 stating that they had no record of my cancellation. There are better products on the market--Don't Buy!!!!

Tech. support was awesome, but had to remove program, have a lot of software programs and Stopzilla interfered with their execution. Regrettable but true.

I downloaded and installed the trail-version of this product... first it will not remove any-thing unless you buy...then I went online to read about it --CNET / download . com --- wooowww. bad reputation. It was really not easy to remove it from my computer and it made my computer very slow. don't it. stay away. I can't believe I actualy installed this peace of junk into my computer.
