One of the more esoteric but dangerous pieces of malware that
might infect you is a rootkit. This software uses tricky techniques
to shield itself from many anti-spyware, anti-malware, and
anti-virus programs. A rootkit hides deep in your system, and
allows someone to take complete control of your PC without your
knowledge. Rootkits typically are spread online in a variety of
ways, such as riding along on another download.
Some anti-virus tools, such as Avast, claim to detect and kill
rootkits. Many don’t. But even if you are using an anti-virus tool
that claims to detect them, you can’t be too safe. So you’d do well
to download, install, and use F-Secure Blacklight Rootkit
Eliminator, a freebie designed to do one thing, and one thing
alone: detect and kill rootkits.
The program looks inside your PC’s folders, files, and hidden
processes, looking for signs that you’ve been infected with a
rootkit. It then tells you whether your system is rootkit-free, or
possibly infected. It lists every possible sign of infection.
Double-click on every one of them, and you’ll be shown more
information, such as a description, the company that made it, the
file location, and so on. You can then use Blacklight Rootkit
Eliminator to get rid of the threat, by renaming the file and
giving it a .ren extension so that it can’t do any further damage.
However, before taking that step, it’s a good idea to search for
the file name on Google and make sure that the file truly is a
rootkit, and not a legitimate file. If your PC continues to
function well after you’ve renamed the file, you can eventually
delete the renamed files.
Note that if you’re not experienced, you might want to stay away
from this program. Renaming and deleting files could possibly wreak
havoc on a PC, so if you’re not comfortable renaming, restoring,
and deleting files–and troubleshooting PCs–you may be courting
