Severity scale:

(68 / 100)

BlockDefense is another bogus security program from the same family as SaveDefense, Trust Ninja, SaveSoldier, SaveKeep and other Winisoft rogueware. This fake application uses false scan results, fake security alerts and other misleading methods to make you think your computer is infected. Once installed and active, it will ask you to buy a full version of the program to remove infections that do not even exist. Do not purchase it. You should uninstall BlockDefense from your computer upon detection.

Basically, Block Defense is just a rename of the rogue applications mentioned above. As you can see it uses the same template but this time with very weird name which doesn't make any sense. In other hand, it does "Block" your "Defence" so maybe it's not so bad name after all. Usually, BlockDefense is promoted through the use of Trojan viruses, fake online anti-spyware scanners, malicious websites and other malware. While running, this parasite will perform fake system scan and report various bogus computer security threats. What is more, the rogue program will constantly display legitimately looking security alerts. It will impersonate Windows Security Center and display notifications that your anti-virus protection is disabled and that you should buy Block Defense to ensure full system protection. Of course, we recommend you not to do so. Otherwise, you will simply lose your money and your credit card details might be sold for cyber-thieves.

BlockDefense will also hijack your web browsers and block security software. If you find that your computer is infected, please use the removal guide below to remove BlockDefense from the system manually for free.
