“My Microsoft Security Essentials found Virus: DOS/Rovnix.Wyesterday and it indicated that the virus was removed. But the virus seemed to keep coming back because MSE repeatedly reported about this virus and removed it. How Can I get rid of this threat completely?”

What is Virus: DOS/Rovnix.W?

Virus: DOS/Rovnix.W is a malicious Volume Boot Record (VBR), which is loaded at boot time. It intercepts the hard disk I/O (input/output) operation, or system memory layout functions, to patch the PC’s boot module. Once your computer gets infected, an error says “Error code 0×80508023. The program could not find the malware and other potentially unwanted software on this computer” will occur on the PC. Though the antivirus software claims that it has removed this virus, the virus is still on the computer. During installation, the virus modifies the registry entries so as to run automatically every time Windows starts. It also tries to tamper with Windows kernel data to load its own malicious driver. As a result, each time you start computer, the threat is loaded without your knowledge and permission.

The malicious driver of the virus carries out a series of harmful actions on the targeted system. For example, it injects other malware components, such as Trojan:Win32/Claretore.L and Trojan:Win32/Vundo, into certain system processes like svchost.exe or other processes related to your web browsers including Mozilla Firefox, Internet Explorer and Google Chrome. Under the circumstances, your system resources will be consumed a lot silently in the background and the CPU is high. The computer performance will become very poor. And you may experience system crash.

Moreover, the virus also provides a private network stack to prevent your PC from using its standard network. Some versions of the malware also contain a backdoor that used to get other malicious components from the server. This is dangerous because more and more malware may be dropped on your computer and the affected computer will be further damaged and compromised. Your important personal information and other confidential data stored on the PC may also be stolen by hackers.

The threat is able to hide deeply in the targeted system. To hide its presence on your PC, the loaded driver intercepts the hard disk I/O (input/output) operation, and returns the original clean copy if the VBR is accessed. So many antivirus programs fail to completely remove it.
