Malware is a big security threat in the present
environment. Some malware are so sophisticated that they cannot be
detected by any technology or software present as on date. They are
detectable after a lapse of considerable period of time that may at
times be years.
There are some very good free
and open source malware detection and removal tools and
softwares as on date and more and more are added on regular basis.
These include Malwarebytes,
ClamAV,
etc. More can be found at the Sourceforge
page.
Malwr
is another free malware analysis service. It allows you to analyse
suspicious files and extract information on their process and network
behavior while being executed. It's built on top of an open source
malware analysis system called Cuckoo
Sandbox.
In order to use Malwr.com you just need to choose
the file to analyse, solve the captcha and submit it. You can choose
an analysis package between the ones available, if none is specified,
Cuckoo Sandbox will try to detect if it's a PE32 or a PDF file and
choose the appropriate package.
If the file format is not recognised, the analysis
will be aborted. You can also specify your email address to receive a
notification when your analysis is ready.
Malwr.com is powered by the Shadowserver
Foundation. It is a product worth trying and commenting.
