  1. Nunya,
    You said a mouthful. Free, it seems, has become just another four-letter word!
    What I once regarded as a trend has become the industry standard in misleading advertising or, at the very least, presentation. Offers like, “Log on for free,” or, “Free download,” burn me up. I guess the advertisers think we’re all morons. Well and good, advertisers. I can logon almost anywhere for free. Downloads are generally free too but how about telling us that the thing won’t have the functionality of a dustpan when I get it. BAIT AND SWITCH is a perfect call. It’s also as illegal as theft.
    I should have gone to law school!

  2. Do you even know the meaning of the concept of free tune up? These programs are not a free tune-up. These programs are a bait and switch, free scan and clear your temp files, but PAY for tune up. Not a single one of these offers a 100% FREE PC TUNEUP.
