Best Antivirus Software virus

What is Best Antivirus Software?

Best Antivirus Software is a rogue antivirus program, which uses fake security scans and warning messages to scare PC users into believing that their computers are infected. It then coerces them to purchase a useless license key in order to remove the 'detected' threats.

This bogus program exploits the Microsoft name in order to make it appear authentic and trick PC users into believing they are using a legitimate security program.

The user interface of Best Antivirus Software is similar to Microsoft Security Essentials (a legitimate free antivirus program), and therefore, you should not mistake these two programs. This malicious program is distributed by Internet criminals using Trojans and fake online security scanner pop-ups.

When installed on your PC, Best Antivirus Software generates various harmless files and then imitates their detection as being malware. This misleading strategy is used to trick computer users into purchasing a license key in order to remove non-existent security infections.

To further scare you into believing that your computer is infected with high risk malware, Best Antivirus Software generates fake warning messages and blocks the execution of your installed Windows programs. In fact, it is an empty software package, which uses pre-generated windows to scare you.

This malicious application 'detects' identical security threats and displays the same warning pop-ups on every computer that it infects.

Best Antivirus Software is a scam created by Cyber criminals who make money from unsuspecting PC users who purchase license keys for their rogue software. The security infections supposedly detected by this program are harmless files falsely-generated on your computer hard drive.

Do not 'Activate full protection' for this program - you will send your money to Internet criminals and your computer will remain infected. If you have already paid for this software, you should contact your credit card company and dispute the charges - explain that you have been tricked into buying a fake antivirus program.

The next step is to remove this bogus program from your PC. This malicious software is derived from a large family of rogue software, which included previous variants called Total Anti Malware Protection, Best Virus Protection, and many others.
