Internet Security
How to be “Reasonably Safe” on the
Internet
The following slides are an
explanation of the terminology used
in the antivirus and antimalware
definitions
Virus

A computer virus is a computer program that
can replicate itself and spread from one
computer to another.
Worms

A computer worm is a self-replicating
malware computer program, which uses a
computer network to send copies of itself to
other nodes (computers on the network) and it
may do so without any user intervention.
Trojan

A Trojan horse, or Trojan, is software that
appears to perform a desirable function for the
user prior to run or install, but (perhaps in
addition to the expected function) steals
information or harms the system.
Keylogger

Keystroke logging (often called keylogging)
is the action of tracking (or logging) the keys
struck on a keyboard, typically in a covert
manner so that the person using the keyboard
is unaware that their actions are being
monitored.
Phishing

Phishing is a way of attempting to acquire
information such as usernames, passwords,
and credit card details by masquerading as a
trustworthy entity in an electronic
communication
Adware

Adware, or advertising-supported software,
is any software package which automatically
plays, displays, or downloads advertisements
to a computer. These advertisements can be in
the form of a pop-up.
Spam

Spam is the use of electronic messaging
systems (including most broadcast media,
digital delivery systems) to send unsolicited
bulk messages indiscriminately.
Root Kit
A rootkit is software that enables
continued privileged access to a
computer while actively hiding its
presence from administrators by
subverting standard operating system
functionality or other applications.
What can you do about all of these

1. Have a good anti-virus with currently
updated virus signatures and scan regularly.

2. Have several spyware removal programs
and scan frequently.

3. Have a good firewall (either hardware or
software preferably both).

And many others
Free versus Paid Programs


All free programs offer fairly good protection
Paid versions offer more protection
Free Antivirus Programs




Protection is very basic
Do not have the in-depth scanning as the paid ones
Do not have as many active scanning modules
Malware protection very basic
Paid Antivirus

More robust antivirus scanning
More active scanning modules
More antimalware scanning prevention

In general are more protective than the free versions


Antimalware Programs






Malwarebytes Antimalware
Super antispyware
Spyware blaster
BoClean
Emsisoft Antimalware
And some others
Antimalware Programs Free vs Paid

Free versions usually have to be updated and
scanned manually.

Paid versions have automatic updating,
scanning on schedule, and finally have active
scanning modules running.
Internet Searching

Programs are available to keep you reasonably
safe doing a search on the internet.

Remember that nothing is ever really safe on
the Internet.

Firewall Recommendation




You can use the built-in Windows firewall
You can use free or paid firewalls
You can use only one firewall at a time
You can use a hardware firewall such as a
router.
Summing Up

You can have all of the best Internet Security
that is available but all of that is useless if the
following is in place
