As rule of thumb, never ever click links in email no matter how normal or ordinary they may look like (especially if you didn’t expect receiving it). Verify first from the sender if it was sent directly to you.
As an example, the link above can install a malware program called Total Security Protection Center (as pictured below). Once you are infected (because you clicked the link you received in email), a report will keep on popping your screen showing you a summary list of the infected files or the infections you have in your computer. This annoying scam pop up will keep on asking you to download the program to disinfect your files and computer, but the truth is, it’s just trying to trick you to pay its licensed version. This is not only annoying but it can slow down your computer and worse, it even gather personal information or activities in your computer.

Spyware is a type of malware that can be installed on computers, and which collects small pieces of information about users without their knowledge.
Let’s be careful out there.
