Is3 sells StopZilla online and other crappy software that doesn't work very good at all and they state on their website at Is3 you have a 1 month no questions asked money back Guarantee if you do not like their software. I been fighting these people for over two months now to get all my money refunded with no luck. They won't credit back all my money and I keep getting the run around when I call them to speak with customer service. If you see any website selling StopZilla, AntiFraud, AntiVirus and MaxPc, you best advice is to avoid them at all cost because they are a pack of scammers that won't back up their Guaranty. These people are terrible people there and are legally stealing from us all by not backing up refunding all your many if you call them in less than one month to say you don't like their product and want you money back. I hate these creeps for making my life Hell by lying to me and basically stealing from me. AVOID THEM AT ALL COST OR IT WILL COST YOU, NOT ONLY MONEY, BUT A PART OF YOUR SANITY ALSO BY TRYING TO GET YOUR MONEY BACK AFTER YOU FIND OUT THEIR SOFTWARE SUCKS.
