Another nice name for the Virus infections. Developers named the infection – Windows Antivirus Care. Of course it has nothing with windows care or antivirus care or care in general. All what this infection does is infects your system, displays fake warnings and asks money to remove these fake infections.
Windows Antivirus Care is a scam. If you bought it, then you should contact your credit card company and dispute the charges. Get rid of Windows Antivirus Care using legitimate antimalware software or try using manual removal instruction if you have some knowledge in system architecture.
