Because of bugs, malware is frequently installed. Attackers are constantly seeking for new ways to fool you into downloading malware. This explains why malware comes in such a wide variety of forms.
Below are some of the causes
Visiting a website that isn’t legal
Many people utilize unauthorized websites to get free access to paid material. Using a VPN to watch pay-per-view sports games or stream the latest blockbuster movie while in the theater has become second nature. However, be aware that these services frequently inflict more harm than good.
Remember the ancient adage, “If it sounds too good to be true, it probably is.” Malware might install itself automatically if you visit an illicit website. Malware-infested pop-ups and other stingers are common on such sites. Have you ever pressed the ‘Play’ button and a new browser tab appears? That could be a symptom of nefarious conduct.
Using services for file sharing
There are some setbacks to sharing files on peer-to-peer networks and downloading software from other websites. P2P file sharing allows users to download and distribute files for free on the Internet, but there are exceptions. Files are frequently transferred between computers. It just takes one malware-infected person to infect everyone else who downloads their files.
Using the Internet to Download Files
Downloading files from untrusted sites or unknown sources is the most prevalent way to receive malware. Make sure you have the most recent version of your web browser to avoid being another unfortunate victim. Furthermore, when you’re going to download something from a web page to your computer, all major browsers include a built-in alert mechanism to make sure that’s what you wanted to do.
Clicking on “your computer is infected” pop-ups
A pop-up arrives on your screen out of nowhere. It may state in bold type that your machine is infected with malware and requires a security update. When you click there, the prophecy comes true. These warning messages frequently provide a link to some solution-based programme that claims to “clean up” the malware but really adds it to your machine. When you click on a link on a web page, pop-ups may appear warning you to stop your anti-virus software. Others advise you to ignore any operating system warnings and keep going.
Using questionable email attachments as a source of information
Malware developers use deceit to get people to download and instal viruses or click on harmful links. To disseminate their malware, they use email. Disguised as something we want or recognise.
Spoof emails might imitate a friend, a bank, or a well-known online business. In this disguised distribution strategy, you may receive an email from a well-known website with an attachment purporting to be a discount code or a free PDF. The convincing wording and recognisable visuals will urge you to open it. With only one click, you may automate a download and have malware in your hands. This trick is known as email spoofing.
Using Infected Removable USB devices
Viruses can propagate via infecting removable drives like USB flash drives, as well as any sort of external storage like your Kindle or an external hard drive. Malware has also been found in USB charging stations in airports, of all places.
If you connect your Kindle to an infected computer’s USB connection just once, you’ll get a virus as well as a fully charged battery. Then, the next time you charge it up at home, you’ve just infected your own computer with spyware.
