It is a type of malware designed to show unsolicited ads during the surfing time of the user. These ads have only one objective of redirecting to the advertising sites, and attempts are made on either selling a product or collecting marketing data from you. The collection of data goes two ways as either you would be giving your information or someone would be taking your information without notifying you.
‘Worm’ is a malicious program that can copy itself from one PC to another (no input required). These worms can replicate themselves quickly for example; worm may infect your device and then send copies to each contact on your email address (a copy of itself). They are most in lethal in spreading out as they are very quick in infecting the system and they propagate all over the internet through a single click of a mouse!
For example, 9 million systems were infected within 96 hours through computer worms.
Spyware has a wide reach and can be found in multiple places (most probably in pop-ups on downloadable files). Hackers can monitor keystroke if spyware gets installed on your device. Moving on, the same people take control over your device, and they can now delete, alter, remove and change your data or even ask ransom for releasing your data to you.
These are quite similar to spyware as they have the same ability to monitor the keyboard actions. But they are rather specialized in noting the key entries only like usernames, passwords, and even bank details. Your identity might be in threat if you ever come across such threat.
Unwanted emails or unwanted marketing emails are what comes to our mind when we think of spam. It is a program that is capable of clogging the mail server along with cluttering the entire mailbox. However, they are not harmful but do possess links which redirect you to threatening pages, phishing sites and more.
These scams are an advanced form of fraudulent attempts made by cybercriminals to obtain confidential information of the users.
For example, you may receive an email saying that your bank account is out of the update and you need to provide your login details to get updated. Don’t ever give up your details to anyone in any case unless you are well aware that the person asking for it is a trusted candidate who wouldn’t take advantage out of your crisis.
Pharming is quite similar to phishing in nature but is rather more complex to understand. This type of attack is created to exploit the DNS system as these pharming sites create online web pages that look similar to legitimate websites and ask you to enter your details. Since they look trustworthy, people or users feel no harm in entering their details. This is where they take advantage out of your situation. Try to be very careful while entering your login details as it is now quite hard to differentiate which site is the actual site. However, all these threats can be easily removed using the best file security and password protection software.
