SPYWARE

Spyware is a specific type of malware, its a covert software program which scans or monitors activities on a computer or system, online or offline doesnt matter It transmits the gathered information to other computers or locations on the internet. This informtion is usually collected and sent to third-parties, often with malicious intent, without the user even knowing, spyware can also make changes to the users computer on wich it is installed. Among the different types of malware there are spyware is one of the worst.

WHAT SPYWARE CAN DO!

Spyware can collect information and send it to the attacker (all the above apply to Spyware) this can be a major problem if you use internet banking at the worse case, then can do as little as tracking cookies, mostly the actions of Spyware programs are just simply annoying like degrading the performance of the users computer by effecting the pc speed. You can check the danger or risk of a Spyware program if detected on your pc at these websites

Symantec     Spywareguide

Not all Spyware is bad though to some they Spyware can be very useful Example: a users online activitie scan be monitored and used to target ads or steer the user to websites that can provide goods or service the the user wishes to see or can benifit from in some way. May i add that once permission is granted, covert software cannot be called Spyware!

HOW IS SPYWARE INSTALLED

There are so many ways that Spyware can be installed onto a machine most will work in stealth mode. The most common way is via an internet connection with so many computers conected to the internet its an easy threat for infection. As stated in the previous section Spyware can be installed through viruses, worms, adware, Trojan horse programs, Keyloggers, and obviously websites, some tricks to install spyware could be :

  1. Hideing inside another program: The Spyware hides inside another program. For example, when a P2P program is installed the hidden program, typically Spyware or Adware is also installed.
  2. Useing confuseing legal jargon : The EULA is written in such a way so that the user just get so confused or simply its just so long and boreing it seems like useless information and users skip section or just agrees it, which gives the vendor enough leeway to install the Spyware legally.
  3. Being persistent and annoying  : When your surfing the web you might get a window pop-up (pop_ups) which when you click the decline button it just keeps poping up and doesnt go away so eventually some users will just accept it through frustration.
  4. Offering free scanning              : Some website offer a free scan, after the scan is complete they show a number of results showing something has been found, in some cases the results show cookies which are not Spyware, so the user is scared into buying the other half of the program the removal tool !
