Simon Pell gave a presentation on malware threats facing small businesses. He defined different types of malware like viruses, trojans, worms, and rootkits. Viruses self-replicate and infect files, while trojans and worms do not self-replicate but can still damage files. Rootkits are used to hide other malware. Spyware/adware collects user information without consent. Cookies are small text files that store website preferences. Pell stressed the importance of using updated antivirus software, firewalls, and being cautious of downloads. Firewalls can control network access and applications without slowing performance. Unified threat management provides additional protections like blocking suspicious websites and spam.

2. What is Malware?
Are you protected?

3. All the various threats can be called
Malware
The word malware comes from the
combination of Malicious and software.
It refers to viruses, worms, spyware,
adware, hoaxes etc etc.

4. Did you know that over 90% of small
businesses have anti-virus solutions in place?
Yet almost half are still getting attacked by
e-threats!!

5. What’s a Virus?

6. A virus is a piece of code or software that
is designed to damage your files and
programs, they are designed to replicate and
spread to other computers via email or across
your local area network (LAN).

7. What is a Trojan?

8. What is a Trojan?
As the name suggests a trojan is a piece of
malicious code disguised as an apparently harmless
program, which in many cases when run releases the
malicious code hidden in it.
Unlike viruses trojans do not self replicate, but like
viruses they are designed to destroy files or programs. In
many cases they can capture and resend data to external
addresses or open the PC to be controlled by remote users,
referred to as @cyber-crooks', usually there to steal
passwords and banking information. Definitely not what a
small business needs.

9. What is a Worm?
Worms are programs that make copies of themselves in
different places in your PC.
The object of this is to slow your PC or network down to make it
unusable. Unlike viruses they do not infect files.
Worms are usually spread using social engineering, they make
them to look attractive by use of attractive names to hide the files.
Most popular names relate to sex, famous people, free software
anything to make them seem appealing.
Worms are more geared to make financial gain and bring
notoriety to the creator.
Most recently reported in the press was the cornflicker virus.

10. What is a RootKit?
These are programs designed to hide objects
such as files, windows registry entries or
processes.
A rootkit itself is not malicious but is used by
writers of malware to cover their tracks in
infected computers.
The first examples of malware using rootkits
to hide themselves appeared in 2005.
Spyware, Adware and Bots added these
characteristics to their own to try to avoid
detection.

11. Spyware/Adware
Spyware and Adware are programs that display adverts
associated with the product or service being offered by the creator of
the program. It can be installed in a number of ways, in many cases
without the users consent or without knowledge of its function.
The term Adware and Spyware can be controversial, as a
rule they are not used for criminal intent but to advertise products ad
services. information collected does not include bank details but
more like web pages visited or favourites etc.

12. What are Cookies

13. What are Cookies
Cookies are small text files stored on a computer by your
web browser after visiting a web page. The information stored by the
cookies has a number of uses. It can be used to personalise a web
page for the next time you visit, to collect demographic information
about the visitors to the page or to monitor banner clicks.
A good example is when you revisit a page and it says
"Welcome back <your name>" such as Ebay or Amazon etc.
While a cookie in itself is not malicious it could be used by
malicious code to affect a users privacy as it can create a users
profile of browsing activity and send it to third parties.
