What Is Unwanted Computer Software?

Denise Wilkinson

Unwanted computer software, also known as malware, is a type of program that is designed to disrupt or damage computer operations without the user’s consent. Malware can come in various forms – viruses, worms, Trojans, spyware, and adware. All these forms of malware can cause serious harm to your computer system and your personal data.

Viruses: A virus is a malicious program that attaches itself to a legitimate program or file on your computer. Once the virus has attached itself, it can replicate and spread throughout your system. Viruses can cause damage to files, programs and even hardware.

Worms: Worms are similar to viruses but they do not need a host program to attach themselves to. Instead, they exploit vulnerabilities in operating systems or software applications directly. Worms can spread quickly through networks and the internet.

Trojans: A Trojan is a type of malware that disguises itself as a legitimate program or file but once it’s installed on your system it gives hackers access to your personal data or allows them to take control of your computer remotely.

Spyware: Spyware is designed to monitor your online activity and collect personal information such as passwords or credit card numbers without your knowledge. This information can be used for identity theft or sold on the black market.

Adware: Adware is a type of malware that displays unwanted advertisements on your computer screen. This type of malware may also track your online activity and collect personal information.

It’s important to note that malware infections can happen through various ways such as downloading attachments from emails, clicking on pop-ups or ads online, visiting suspicious websites or even using infected USB drives.

To avoid unwanted software infections, you should install reliable antivirus software and keep it updated regularly. You should also be cautious while downloading files from unknown sources and avoid clicking on suspicious links or ads.

In conclusion, unwanted computer software can cause serious damage to your computer system and personal data. It’s important to take necessary precautions and be cautious while browsing the internet. Stay safe by keeping your software updated, installing reliable antivirus software, and avoiding suspicious websites and downloads.
