According the the Microsoft web-site, "...Rogue security software reports a virus, even though your computer is actually clean. The software might also fail to report viruses when your computer is infected. Inversely, sometimes, when you download rogue security software, it will install a virus or other malicious software on your computer so that the software has something to detect." This is the case with this company, Best of the Soft, BAKU, Arizona. Thier malware will not allow you to procees without opening a screen which claims to have found malware which only their product can irradicate and then guides you to buy their security software by using your credit card. Beware, though, since you will have a charge for NOTHING and, possibly, a trojan horse which will steal your credit card information for future use. Monitor your account(s) carefully and, if you want to prevent future mis-use, get your credit card-issuing institution to change the card on your account. Dispute the charge for their useless software (there is no download of any security software, just continued virus infection.)
