Beware net users: There are many pop-up ads and net sites offering you “100% free” services like a free virus scan, a free registry scan, one that was reported to me even had a free comprehensive medical evaluation with over 300 questions, but the hook is at the end of loading these scanning programs or filling out many pages of some questionaire the very last page has a little surprise. You can view the medical results or make the needed fix with the registry or software, but only if you pay and usually it’s around $40 bucks. It’s a gotcha ad!
Sometimes these companies will have placed an invasive spyware program in your computer for their marketing purposes, so even if you remove the orignal program, they still have you on their radar.
My suggestion is, be very suspicious of anything for “free” unless its from a trusted, certificated “shareware” site, even then I’ve found some problems.
