Beware Bogus Security Software

Intego has spotted one such company, claiming to sell Macintosh antivirus software: MacGuard

If you are gullible enough to purchase this software from a company you have never heard of, who has no references, and whose web site is vague and imprecise, it is likely that you will find additional charges on your credit card. ArsTechnica reports that more than 30 million people have been scammed by such software.​
