The ultimate resource for malware removal and virus protection
The rapid rotation of Antivirus Soft scareware is currently involving System-defender.net domain. Considering the characteristic features of System-defender.net, we can confidently classify it as a browser hijacker, i.e. a site to which rogue anti-spyware diverts your Internet sessions. Now, it’s time we provided some additional information. If Antivirus Soft scareware enters your workstation, it pops up now and again and gives you some ads from the system tray as well as scanners pretending to check your PC for malware. This junkware deliberately lies to you through its numerous false detection reports – in order to convince you to register its commercial version. If you chance to click one of them, System-defender.net will be automatically navigated to. On System-defender.net, the only option that actually works is to purchase Antivirus Soft. Additionally, when you try to go to random websites, Antivirus Soft may direct you to System-defender.microsoft.com instead of the targeted URL. This is a trick that has existed since all predecessors of Antivirus Soft rogue anti-spyware were developed, i.e. for years. No need to say that System-defender.microsoft.com is not a real domain name; it’s merely a product of malware-triggered HOSTS file modification. The trusty ‘microsoft’ component of the URL is just bait for you to go ahead and trust that web source. Our final notice about System-defender.net hijacker is that it’s just the top of the Antivirus Soft malware ‘iceberg’. If you need to prevent that malicious site from popping up on you, it’s required to remove Antivirus Soft from your computer. You can do it manually or use an automatic solution to get the ‘dirty’ job done for you (please analyze the passage under this article).
