3. Which is the biggest threat to Internet? Why?
Answers
Answer:
Spam
The fact that most of our emails accounts come with a ‘Spam’ or ‘Junk’ folder insinuates that spam emails are a huge issue, with more than 50% of emails being syphoned into these folders. Aside from being an annoyance, spam emails are not a direct threat. However, many can contain malware.
Adware
Adware is a type of malware software that displays unwanted ads when a user is surfing the internet. The ads often redirect your searches to advertising websites and collect marketing-type data about you, behind your back, which is considered malicious.
Adware is often included in many shareware or freeware downloads as a legitimate way of generating advertising revenues that help fund development. However, some websites are infected with malicious adware that us automatically downloaded to your computer. When this has been completed, Trojans can be used.
Trojan
Trojans leave your computer completely unprotected, which can mean that hackers can steal any data from your system. Trojans often present themselves as harmless computer programmes so that hackers can penetrate your computer without being detected.
Virus
One of the most talked about internet threats is a virus. Viruses usually attach themselves covertly to downloads as they are designed to spread at an alarming rate. Viruses are often attached to files for download, shared via CDs, DVDs, and USB sticks, or loaded on to computers by opening infected email attachments.
