WinAntiVirus Best seems to be corrupt anti-spyware program that might be using false positive as goad to purchase. It is a clone of the illegally distributed Spy Sheriff rogue and other notorious products.
We couldn’t test WinAntiVirus Best, as the official web site does not provide any trial or free version at the moment. However, the application is definitely a clone of Spy Sheriff, so most likely it uses false positives.
WinAntiVirus Best is a clone of Spy Sheriff, Brave Sentry, SpywareNo!, SpyDemolisher and other corrupt anti-spyware programs. All these products are known to have identical user interfaces. They produce similar deceptive scan results.
The official web site is www.protectwin.com. Not only it doesn’t provide any downloads, but also its Download and Help Desk pages are far from being clear and trusted. “not for russian” – that’s what you get when open any of those pages in your web browser. It must be noted that neither of our test computers are located in Russian Federation. Furthermore, our IP address ranges do not even look as Russian. Why do we get such a strange page? Most likely the final version of the corrupt program is not ready yet. See a screenshot provided below.
The official web site also contains text copied from www.spysheriff.com, the Spy Sheriff site. See another screenshot below.
DO NOT buy this product!
