What is the most common type of malware?
The most common type of malware is a virus. A virus is a program that is designed to spread itself and infect other computers. It can do this by attaching itself to email messages or files that are shared on networks. Once a virus is on your computer, it can start making copies of itself and spreading to other computers. Viruses can also damage files and cause your computer to crash.
There are many different types of viruses, but some of the most common include:
-Trojan Horse: A Trojan horse is a type of virus that disguise itself as something else, like a legitimate program or file. Once it’s on your computer, it can do harmful things, like delete files, steal information, or damage your system.
-Worm: A worm is a type of virus that is designed to spread itself by making copies of itself and sending them to other computers on a network.
-Spyware: Spyware is a type of malware that is designed to gather information about you without your knowledge. It can do this by tracking the websites you visit and the files you download. Spyware can also steal personal information, like your passwords or credit card numbers.
-Adware: Adware is a type of malware that displays ads on your computer. It can be annoying, but it’s usually not harmful.
-Ransomware: Ransomware is a type of malware that puts a lock on your computer and encrypts your files. It then demands a ransom, usually in the form of Bitcoin, in order to unlock your computer and give you access to your files. Ransomware can be very harmful because it can prevent you from accessing your computer or your files.
The best way to protect your computer from malware is to install an antivirus program and keep it up-to-date. You should also be careful about what you download and install, and only install programs from trusted sources.
What are the different methods that malware can use to infect a computer?
There are many ways malware can infect a computer, but some of the most common methods include:
Via an email attachment: This is perhaps the most common way malware is spread. The email may look completely legitimate, and may even come from someone you know. But if it has an attachment, and you open that attachment, the malware will be installed on your computer.
Via a malicious website: Sometimes, just visiting a website can be enough to get infected with malware. This is especially true if you click on any ads or links on the site. The website may look completely legitimate, but it will have code embedded in it that will automatically download and install the malware on your computer.
Via a USB drive: Many people use USB drives to transfer data from one computer to another. However, if you use a USB drive that is infected with malware, the malware will be copied onto your computer as well.
