A bit of good news for computer users: Federal authorities have shut down several alleged tech support scammers working out of Florida, Iowa, Nevada and Canada, freezing their assets and seizing control of their businesses. The action was one of the largest in the U.S. against scammers, who bilk consumers out of an estimated $1.5 billion annually with bogus tales of infected Windows PCs and Apple Macs, high-pressure sales tactics, and grossly overpriced services and software. After the Federal Trade Commission (FTC) filed complaints against six companies and six individuals in late June, courts shuttered alleged scammers doing business under names like Big Dog Solutions, Help Desk National, Help Desk Global, PC Help Desk, Inbound Call Specialist, BlackOptek CE, 9138242 Canada and Digital Growth Properties. Five of the six operated as a single enterprise, muddying the waters with multiple names. The firms' websites were closed, their assets were frozen, and court-appointed receivers were put in charge of the companies. The FTC announced the shutdowns on July 8. Read the rest... It's good start, now if only the feds would shutdown those 'Windows tech support' cold-call scammers.
