Can virus modify the data?
Some viruses employ techniques that make detection by means of signatures difficult but probably not impossible. These viruses modify their code on each infection. That is, each infected file contains a different variant of the virus.
What are the consequences of rootkits?
Potential consequences of a rootkit include: Concealed malware – Rootkits allow attackers to install additional malware on infected computers. They hide malicious programs from users and any anti-virus software installed on a computer.

What is the difference between a kernel mode rootkit and a user made rootkit?
The drawback to user-mode rootkits is that they can be detected by code running in kernel mode. FU is a non-persistent kernel-mode rootkit that is very difficult to detect. Since it is not persistent, no files are stored on the compromised system. Since it is a kernel-mode rootkit, it is very hard to detect.
How does a rootkit work?
A rootkit is a collection of computer software, typically malicious, that is designed to grant an unauthorized user access to a computer or certain programs. Once a rootkit is installed, it is easy to mask its presence, so an attacker can maintain privileged access while remaining undetected.
