What are Computer Rootkits
A rootkit is a collection of tools (programs) that enable administrator-level access to a computer or computer network. Typically, a cracker installs a rootkit on a computer after first obtaining user-level access, either by exploiting a known vulnerability or cracking a password. Once the rootkit is installed, it allows the attacker to mask intrusion and gain root or privileged access to the computer and, possibly, other machines on the network.
A Typical Rootkit Activity in Computers
Typically, rootkits act to obscure their presence on the system through subversion or evasion of standard operating system security scan and surveillance mechanisms such as anti-virus or anti-spyware scan. Often, they are Trojans as well, thus fooling users into believing they are safe to run on their systems.
F-Secure BlackLight – Protection Against Computer Rootkit Activity
F-Secure BlackLight is a freeware Rootkit elimitaing application from the reputed security vendor F-Secure. Blcklight can detect and eliminate active rootkits from the computer, whereas traditional antivirus scanners can’t detect active rootkits.
On a normal system F-Secure BlackLight does not confront the user with a long list of suspected objects. This makes F-Secure BlackLight useful even for non-technical users. F-Secure BlackLight Rootkit Elimination Technology can be used in the background during normal system operation. Other available scanners require a reboot during scan or may produce false positives if the system is used during scanning.
