Rootkit Removal Tools and Help

What are Rootkits?
Rootkits orginated on UNIX platform computers but have evolved and invaded Windows computers in the last few years. The term rootkit comes from the fact that the program would gain administrative priviledges (root access) on the UNIX system and then hide all traces of the program so it could work behind the scenes without being detected.

On Windows systems, rootkits are being used by spyware, adware, viruses,  trojans, and other malware to hide the system processes are work undetected. Slow running computers, unwanted popup ads, redirection of websites and search can all be signs of a rootkit. However it takes special software to detect them. Since rootkits are designed to hide from users they also hide from most antivirus and antispyware software. This is why many of the antivirus makers and other companies have produced special rootkit removal tools in the last few years.

The general rule of thumb is if you are still having misc. issues including blue screens, system slowdowns, and other problems and none of your virus and spyware tools have detected a problem, you might have a rootkit.

Many of those electronic greeting card spams that you may have seen in the last few months have contained rootkits. The spam needing you to download "Microsoft Data Access" to view the electronic card contained a rootkit, and without special software to analyze the computer the rootkit stayed undetected. Sony had a terrible public relations fiasco with rootkits awhile back as well, and is still under scrutiny because of their MicroVault USM-F software used for fingerprint-reading flash drives.

So if you think you have been infected with a rootkit or simply want to scan your system for one use the list below to read about and download a rootkit removal tool.

Recovery from a Rootkit Invasion

The problem with rootkits is the fact that they can take over a computer and download and install other software. One rootkit removal tool might find one rootkit while another might find something totally different. Its always a good idea to use multiple rootkit removal tools to inspect your computer, just as its a good idea to use multiple antivirus scanners to scan for problems. In many cases, the rootkit can be identified and removed, however on occasion the damage may be too great, or the private information residing on the computer may have been compromised too much. In these cases, you may have to resort to completely reformatting and reinstalling the operating system. Although this recommendation should be used as a last resort, it still remains a possibility when dealing with silent but deadly rootkits.
