3B ERROR DOCTOR? - Free Download

Question

HiyaI had the opportunity to download some 3B software which claimed to fix PC problems incuding registry entries. I started the download and immediately got a warning from McAfee adviser that the site had been reported as allegedly downloading spyware. I decided to ignore this (reckless fool that I am) when my Anti Virus software kicked in to warn that it was trying to download a virus! At this point I aborted the download.Can anyone explain why this happened or is it simply that I should not trust 3B?Lee
