An Unwanted Program Running on a Computer is Called a: Malware or Potentially Unwanted Program (PUP)
An unwanted program running on your computer can be frustrating and potentially harmful. While the most common term is malware, it's important to understand that this is a broad category, and the specific type of unwanted program will determine its impact. Let's delve into the details.
What is Malware?
Malware, short for "malicious software," is a catch-all term for any software designed to damage, disrupt, or gain unauthorized access to a computer system. This includes viruses, worms, Trojans, ransomware, spyware, and adware. Each type behaves differently:
- Viruses: These programs replicate themselves and spread to other files or systems, often causing damage as they spread.
- Worms: Similar to viruses, but they spread independently without needing to be attached to another program or file.
- Trojans: These programs disguise themselves as legitimate software to trick users into installing them. They then perform malicious actions, such as stealing data or installing other malware.
- Ransomware: This type of malware encrypts your files and demands a ransom for their release.
- Spyware: This software secretly monitors your online activity, often stealing your personal information.
- Adware: This software displays unwanted advertisements, often interrupting your work or browsing experience.
What are Potentially Unwanted Programs (PUPs)?
Potentially unwanted programs (PUPs) are applications that might not be strictly malicious but are often unwanted by the user. They often come bundled with other software and can cause various issues, such as:
- Slowing down your computer: PUPs can consume system resources, leading to performance issues.
- Displaying unwanted ads: These can be intrusive and disruptive.
- Changing your browser settings: PUPs might alter your homepage, search engine, or other browser settings without your permission.
- Tracking your online activity: While not always malicious, this can be a privacy concern.
While not as overtly damaging as some forms of malware, PUPs can still be incredibly annoying and disruptive to your computer's performance and your overall online experience.
What's the difference between Malware and PUPs?
The key difference lies in intent. Malware is intentionally designed to cause harm. PUPs, on the other hand, might not have malicious intent, but their presence is unwanted and often detrimental to the user experience. The line can be blurry, as some PUPs might contain malware or lead to malware infections.
How can I remove unwanted programs?
Removing unwanted programs requires caution. A reliable antivirus program is crucial for detecting and removing malware. For PUPs, you might need to manually uninstall them through your operating system's control panel or use specialized removal tools. Always ensure you're using legitimate software and proceed cautiously.
What should I do if I suspect malware on my computer?
If you suspect malware on your computer, immediately disconnect from the internet to prevent further spread. Run a full scan with your antivirus software. If the problem persists, consider seeking help from a computer professional.
In conclusion, while the simplest answer to "An unwanted program running on a computer is called a...?" is malware, the term encompasses a wide range of threats. Understanding the nuances between malware and PUPs is crucial for protecting your computer and your data. Remember proactive measures like keeping your software updated and practicing safe online habits are your best defense against unwanted programs.
