System Defence

With all the sophistication invested into fake security applications these days, it has become increasingly more and more difficult for even experienced users to distinguish between genuine and seditious rogue security applications such as System Defence. This rubbish rogue antispyware application was designed especially to fleece unsuspecting consumers out of their hard earned money, while leaving them with nothing of value in return.

System Defence will use any tactic at its disposal to facilitate its seditious intrusion into the system. This will usually entail making use of deceitful browser hijacking websites and bogus online malware scanners, as well as infected online flash ads. As of late it has also been reported that System Defence bundles its Trojans and malware together with other third party security downloads and updates.

Once the rogue manages to enter the system it will start its attack against the system by initiating a fake system scan which will lead to many fake reports of bogus threats being present on the system. However, users are urged never to believe any of the correspondence received from this rogue as its developers is only after your money while leaving you with nothing of value in return.

Some of the fake alerts to be on the lookout for include the following:
