Why do I see "Firewall Warning" on my desktop?

"Firewall Warning" is a misleading pop up message which shouldn't be taken for granted. No matter how trustworthy it looks, it has nothing to do with Microsoft and similar companies that are considered well known and reputable. It is just a false security warning which is generated by adware-type programs. Such programs can infiltrate your computer without any warning, so make sure you are careful when installing download managers, PDF creators, video streaming software and similar programs because they can be filled with optional components. Once they enter the system, they modify system settings, hijack web browsers and start causing fake ads. One of such ads is "Firewall Warning" pop-up notification that belongs to Tech Support Scam group of viruses. Their aim is to trick people into contacting the fake Tech support service which is a costly service that cannot fix your computer in any way. Please, do NOT fall for "Firewall Warning" virus and never call the number which is given in this alert. In this case, you should remove adware that is responsible for showing you with scam message. For that, use Reimage.

The earlier version of "Firewall Warning" scam was used to promote the rogue anti-spyware program known as WinPC Antivirus. If you have already installed it, you must remove it because this program can easily initiate lots of malicious activities on your computer.

You must remove Win PC Antivirus virus because the result of keeping such software is the money loss. The malicious installer is mostly spread with the help of such "Firewall Warning" ads:

WinPCAntivirus has detected that somebody is trying to transfer your private data via Internet. We strongly recommend you to block the attack immediately. Details of the attack: remote host transfer IP 97.216.34.74; remote user computer name 'FORENSICS'
