 1. DIFFERENCE BETWEEN SPYWARE AND MALWARE                      GO TO INDEX

   1. Malware covers a lot of different software; Spyware is just one of them.

   2. Spyware often doesn’t cause major damage but other malware can.

   3. While other malware can impair the function of your computer, spyware can
      extract personal information like credit card numbers.

   4. Spyware takes up processing power and a part of the bandwidth of your internet
      connection.

 2. DIFFERENCE BETWEEN VIRUS AND SPYWARE                    GO TO INDEX

  1. Viruses started rather innocently a long time ago but eventually evolved into a
     harmful digital entity while spyware is more recent and created purely for malicious
     reasons.

  2. Viruses ultimately destroy computer systems (software and hardware). Spyware is
     not gravely destructive in terms of computer damage but the unwanted
     applications it installs can be an annoyance.

  3. A virus is a general term which has a distinctive characteristic of replicating and
    modifying files. It also comes in many types like worms and trojans. Spyware, on
    the other hand is specific. It can qualify as a virus since some can also replicate
    files.

   4.Viruses aim to disrupt human to computer interactivity while spyware stealthily
     monitor computer activity.

3. DIFFERENCE BETWEEN WORM AND VIRUS                  GO TO INDEX

1. Virus needs hosts while worms do not.

2. Worms can spread quicker than virus because it does not need human action to
   replicate.

3. Worms often disguise themselves as DLLs or system files to avoid detection.

4. For both, the payload carries code that does the real damage.

4. DIFFERENCE BETWEEN ADWARE AND SPYWARE                     GO TO INDEX

ADWARE

1. Adware are software applications that are designed to allow a number of pop up
   advertisements straight to the personal computers of potential customers and clients.

2. These advertisements allow Internet browsers to download certain programs free of
   charge since these pop up advertisements contribute to the payment of the use of
   these programs.

3. These are currently seen in trial programs which offer the potential customer the
   ability to evaluate and make his or her decision on whether to purchase the license or
   not.

4. For as long as the customer does not purchase the program and is still within the trial
   period, the adware application will generate a variety of relevant advertisements to
   provide free usage of the said program without compromising the amount of profit
   generated by the company that developed the program.

5. Once the customer purchases the program over the Internet, the adware software
   application is then disabled by the computer program and the user can now be
   able to utilize the computer program without the advertisements.
SPYWARE

1. On the other hand, spyware software applications are programs that are embedded
   to certain websites in order to track the purchasing habits of existing customers.

2. The name spyware comes from the fact that the users are not aware of these
   applications.

3. While they are surfing through the website and make a purchase, the spyware
   gathers the purchase information and stores it in a database to allow the company to
   keep track of the types of the products and services that a particular client avails
   and the frequency of the purchases made.

4. With the help of these applications, companies are then able to generate a number of
   Internet marketing strategies to directly market future products and services to these
   customers to further increase the amount of the profit that they generate.

5. DIFFERENCE BETWEEN VIRUS, WORMS, LOGIC BOMBS AND TROJAN HORSES GO TO INDEX



Virus

1. A program that replicates by attaching itself to other programs.

2. The infected program must be executed for a virus to run.

3. Most of the time a system file or a program that you use occasionally.

Worm

1. Program that copies itself throughout a network or the internet without a host program.

2. Creates problems by overloading the network as it replicates.

3. Damaging just by their presence.

4. Overloads memory or hard drive space by replicating repeatedly.

Logic Bomb

1. Dormant code added to software and triggered at a predetermined time or by a

  predetermined event.

Trojan horse

1. Does not need a host program to work; rather, it substitutes itself for a legitimate program.

2. Likely to introduce one or more Viruses into your system.

3. Sometimes called downloaders.

6. DIFFERENCE BETWEEN LEGITIMATE WEBSITE AND PHISHING SCAM                             GO TO INDEX

1. Phishing scams are typically propagated through emails.

2. The crooks send out emails looking like official emails from banks or other financial

  institutions.

3. They insist that you must click on a link and enter personal information or something dire will

  happen, but the link actually takes you to a fake website that looks like the real thing.

4. There are lots of websites and blogs talking about phishing.

5. Here is one that really nets it out:

6. Also, when surfing the web, you should install a free program like McAfee's SiteAdvisor that

  will display warning symbols next to websites that may not be safe to visit. You can download

  free code from the McAfee website at:

7. Remember, if it looks too good to be true, it definitely is! Don't fall for emails or websites that

  claim you have won a prize. And never click on a link in an email.

7. DIFFERENCE BETWEEN SCAM, PHISHING AND RIP OFF                    GO TO INDEX

 A scam is a deliberate attempt to defraud you.

 Phishing is trying to obtain your data to steal your identity and/or credit.

 A rip off is where you are getting something, just not as good a quality, or for as good a price,
 as most people would feel appropriate.

8. DIFFERENCE BETWEEN PHISHING, HACKING AND CRACKING                        GO TO INDEX

Phishing is trying to get some ones username, password, credit card info, Social, or other
personal information by means of a fraudulent message, email, instant message.

Hacking is referred to as getting into another system or computer and copying, modifying, or
just looking a data on that host PC.

Cracking is actually changing code, or modifying a program to function beyond its limits, delete
registration, or any other modification of that program.

9. 4 TYPES OF VIRUSES        GO TO INDEX

There are a lot more than 4 types but these are some of the most common.

1. Worms: A virus that copies itself throughout your computer without you knowing and eats

           through stored data on your computer.


2. Smart Bomb: A multiple type of a virus that waits until activated or a set date to run.


3. Batch: Most common, simple "virus". Though not many real hackers consider it a virus but it

          is a common thing on the internet... It can be used for malicious intent and delete files.
          They come in the .bat extention.
4. Trojan: One of the most common viruses normally installs with another program you

          downloaded. It’s binded, with it. Makes your computer accessible to RATS (Remote

          admin Tools) that allows others to connect to your computer. Or allows you to

          become a part of a botnet.
