The number of malware programs on the Internet has grown very quickly ever since then the late 1990s and is still growing today. Experts think that 31.5% of the world’s computers have some type of malware installed. Today, it is use by both black hat hackers and governments, to steal personal, financial, or business information.
Common way to get malware into computer is through email attachments. Or malware installs itself is when a victim clicks a website with the malware hidden on it. This is mention as drive-by downloading. People who write it also get their programs onto computers by attaching them to real programs that people want. This is most common with pirated programs. This is because the downloader was doing something illegal and cannot complain to the authorities without getting in trouble themselves. However, some non-piracy websites also put malware in a download with real, legal software in a process known as bundling.
Computer security or anti-malware software is usually good at stopping malware from installing itself. When security software is not install, it can get into the computer. Getting rid can be difficult, even when using programs designed to remove it.
