There are websites that ask you to download a program to make your computer perform faster. This can become dangerous if the person using the computer has no idea of what these programs can do. Downloading these programs can also download viruses and malwares. Most of the time, the programs are of no use at all. They just entice users to download it along with the dangerous malwares.
When a malware is downloaded, other people who have evil content can “see” what you are doing. By seeing, they are able to see the sites that you have accessing, the files that you have modifying and everything that you are doing in your computer. When they are able to see what you are doing, they can have access to sensitive information that is supposedly private.
Malwares usually are made to get sensitive information. When they are able to see your computer, they’ll be able to determine the username and password. If you use your credit card online, they can use your credit card information from your transaction history. If you are fond of using social media, they can even steal your account and your identity.
It is important to remind everyone in the house to be wary about downloading programs because they might accidentally download malwares as well. Only download from legit sources and especially if you know that the program you are using is legitimate. Most antivirus programs today have built in malware detection to detect malware and to get rid of it as soon as it is detected.
