Cybercrime consists various online threats, including cyberbullying, online predators, exposure to inappropriate content, and scams.
If someone other than your parent or teacher asks for your computer password, you should not share it with them. It's best to politely decline and explain that you're not comfortable sharing your password.
A "hacker" is a person who uses their technical skills, particularly in information technology, to achieve goals and solve problems, sometimes in non-standard ways.
The best kind of password is one that is long, random, and unique to each account. Aim for at least 12-16 characters, including a mix of uppercase and lowercase letters, numbers, and symbols. Avoid using personal information or common words, and consider using a password manager to generate and store complex passwords.
A computer virus is a type of malicious software that can replicate itself and spread to other computers, often causing damage to data and software. It attaches itself to a program or file, and when executed, it can disrupt systems, cause operational issues, and lead to data loss or leakage.
Antivirus software is a type of program designed to detect, prevent, and remove malicious software, commonly known as malware, from a computer or other digital device. It acts as a security guard, constantly monitoring your system for threats and blocking or removing them.
Computer viruses typically infect devices through user actions, often involving opening infected files or clicking malicious links. Common methods include opening email attachments, downloading files from untrusted sources, visiting compromised websites, or using infected pen drives.
A common sign of a computer virus is unexpected and frequent pop-up ads or a noticeably slower computer performance. Other signs include your web browser homepage changing without your permission, unfamiliar programs running, emails sent automatically from your account, and your security software malfunctioning.
To protect your computer from viruses, always install reputable antivirus software and keep it updated, scan regularly, update your operating system and applications, and practice safe browsing habits.
Spam refers to unsolicited, unwanted, and often irrelevant electronic messages, usually sent in bulk to a large number of recipients. While often associated with email, spam can also be found in other forms like text messages, social media, and phone calls. It's typically used for commercial purposes like advertising, but can also be a vector for scams, phishing, or malware.
