Sonfrus

According to Microsoft researchers, Sonfrus started infecting Windows systems in August of 2011; unfortunately, the attacks continue, and you might get your computer infected soon enough, if you are not careful. The infection, which is also known by such names as Rogue:Win32/Sonfrus, TR/Sonfrus.A.3 and Rogue!IK, is controlled with one extremely dangerous executable (svchost.exe) and can infect your system with such rogue antispywares as AV Security 2012, System Security 2012, AV Protection Online or Security Guard 2012.

With these infections inside your computer, you will notice ridiculous computer scanner, reporting completely fictitious infections, and various deceiving security notifications will flood your screen. Below are some of the examples, which will force you to purchase a bogus security application license, for alleged removal operations to go into action. These rogues are only meant to get your money, so whatever you do, stay away from any purchase or removal recommendations, as these security applications are fake.

Unfortunately these rogues are just one side of the Sonfrus infection, and you should learn all that the malignant svchost.exe can do inside your PC. The executable can add, delete, hijack processes, modify runtime policies, tamper with Windows Security Center, steal personal data from autoexec.bat file, steal contact information, or disable safe mode, all of which could make it hard for you to discover and remove Sonfrus components. Additionally, the infectious file can connect to the Internet, install malware, implement browser helper objects, or even use your system to spread the infection via infected USB drives. Svchost.exe is a polymorphic cloaked infection, and it can use a name of any legal Windows file to hide it from removal. In fact, the malignant executable can stay in your system with any alias names, so be aware that taskmgr.exe, win32.exe, services.exe, debug.exe, lsass.exe, smss.exe could identify Sonfrus.

Rogue antispywares are extremely latent and vicious infections, but you should be extremely careful with those that belong to Sonfrus, because before you know it, you will have lost your money, and your system will be unprotected against additional malware attacks. And since infection’s files can be polymorphic, or be hidden from detection and removal, we do not recommend venturing into manual removal operations. To delete Sonfrus components you should trust automatic removal tools, and we can assure you that if you implement legal software to protect your operating Windows system, you will not have to worry about malware invasions any time soon.
