System Defence is a fake security program that uses a combination of web browser attacks, promotional websites and misleading system warnings to make you think that buying System Defence might be a good idea. SpywareRemove.com malware researchers, however, beg to differ, and have also noted other risks that come along with System Defence, besides its inaccurate warning pop-ups– including browser redirect attacks, blocked software and system settings that are changed without your permission. System Defence infections should be removed with a trustworthy anti-malware program, which, if performed properly, should also put a stop to browser redirects and other symptoms of a scamware attack. If you've spent money on System Defence already, you should immediately cancel your credit card to safeguard the rest of your finances before System Defence's criminal maintainers have a chance to plunder anew.

The Tally of Reasons Why System Defence is a System Threat

System Defence, like other rogue security programs that belong to the , isn't capable of detecting spyware, keyloggers, Trojans, viruses or other PC threats. However, in System Defence's quest to pretend that System Defence can do so, System Defence can cause a wide range of problems, including:

  • Displaying false error messages. These errors can announce that programs are infected, that parts of Windows are damaged or even that your personal information is being threatened by spyware.
  • Blocking security programs. System Defence may prevent you from using anti-malware programs or other Windows utilities, although disabling System Defence with a Safe Mode boot will allow you to access your software again, in most cases.
  • Hijacking your web browser, a la Google Redirect Virus. System Defence may redirect your browser to System-Defence.com if you attempt to use another site or block you from using normal sites by creating fake error screens.

Since System Defence will start without your permission and strive to remain active constantly, only Safe Mode and other anti-malware procedures can stop System Defence from causing these attacks. Among System Defence clones are

Setting Up a Perimeter Against System Defence Attacks

Avoiding System Defence infections also requires that you avoid System-Defence.com, the website that System Defence uses to market itself to the masses. Any contact with this site can result in drive-by-download attacks that install System Defence and System-Defence.com browser hijackers on your PC, so avoidance is paramount. SpywareRemove.com malware researchers also recommend that you be on guard against suspicious system scanners that claim to find infections on your computer, since these scanner simulations are a top method of scamware proliferation. Always scan your computer with an anti-malware program of good repute and avoid scanners that you haven't verified to be trustworthy from several sources.

Unfortunately, because one slip-up is all that it takes for System Defence is to be installed without your consent, knowing how to remove System Defence can also be crucial. Although System Defence may cause browser redirect attacks (similar to a Google Redirect Virus) and may interfere with various programs, you shouldn't attempt to uninstall these programs or change their settings to fix these problems. System Defence-derived problems can be stopped only once you delete System Defence itself, ideally by using an anti-malware application while Windows is running in Safe Mode.
