Fan Motors
Manufacturers Autorun-based malware has always been on the top of the
worldwide e-threat database as they don’t need any specific program to get
operated and start spreading the infection across PCs and networks. Various
dangerous infections such as the Conficker worm (Win32.Worm.Downadup),
Trojan.AutorunInf, Worm.Autorun.VHD and many other popular threats fall under
this category. The infection generally enters into your devices via an infected
USB drive that has been plugged in and used on a targeted PC to damage its
software as well as hardware components. As per ESET malware statistics of
November 2012, the INF/Autorun was the top-most occurring malware worldwide with
a global infection rate of 5.30%.
Autorun feature was initially
introduced with Windows XP to facilitate software installations from CD-ROM
media, but it has rapidly become the most preferred infection vector for variety
of online threats. To combat with the same, several IT manufacturers have
introduced USB immunizers that help in disabling Autorun-related threats before
they access your PC. Bitdefender has topped the charts with its latest USB
software that constantly watches for newly inserted USB storage devices and
immunizes them, once installed. The program will keep your devices away from
such threats even if you’ve accidentally plugged in an infected USB drive that
has not been immunized.
How your machine can be infected?
USB
flash drives are one of the amazing and widely used tools that help in
transferring data from one device to another thus, it brings a tremendous change
in data portability and efficient productivity. With an ever-growing technology
and newly introduced designs, the flash drives are nowadays used by everyone and
have become an easy target for hackers. Cyber criminals plant viruses and other
harmful codes into such drives and when an ignorant user will plug it into a PC,
it will get infected within a few seconds only.
The infections take
advantage of Autorun feature, implemented by Windows developers, and run the
media that has been inserted in our computers automatically. The specially
programmed malware code are commanded in such a manner that the moment the
device goes on Autorun, it begins operating through the same instructions, and
in this way infects the whole machine. The flash drives are meant to be portable
hence, it can infect as many computers on which it is actually
inserted.
How to offer basic protection to your PCs?
No infection
can harm your computers if the device that you’re running is completely guarded
by an efficient antivirus program. Some basic tips while using the Internet
connection and plugging-in external devices can actually prevent such threats.
Users should always keep a check on what they actually do online, the sites they
access and the files they download from unreliable sources. Additionally, always
ensure that you’ve the latest protection system enabled on your device, with an
updated version antivirus and an enabled firewall.
You can easily conduct
a manual scan by sending that file to antivirus software, if you suspect whether
the file is safe or not? Moreover, you can also periodically scan the entire
flash drive to look for infections that might have entered silently and are
sitting inside your drive in a hidden form.
How to protect your system
using USB immunizer?

Suppliers Some antivirus programs scan a USB stick as soon as you plug-in,
but some others (usually the free versions) do not bother to do the same, unless
they are commanded to do it. It has been observed that even if you scan the
drive after plugging it inside your device, then it’s not good enough as the
Autorun code will already be running by then, which is more than enough to
infect your PC. USB Immunizer, a popular category of security software, silently
sits on your taskbar and actively participates in PC protection by acting when
needed i.e. when a USB stick is plugged in. The program is specially developed
to stop and immunize the triggering of Autorun malicious codes that sits inside
the USB flash drives.
