The security of a PC is not limited to the installation of basic protections software like an antivirus or firewall. It is also essential to keep the OS and all installed softwares up-to-date.
A vulnerability or a flaw, is often due to a programming error, bug or software malfunction, located in one or more components of the operating system or installed softwares. In general, they correspond to unexpected actions triggered by the software. A vulnerability can be exploited for malicious purposes, e.g the initial purpose of an application can be modified, making it remotely execute malicious code or facilitate the installation or downloading infections. So these uncorrected flaws substantially increase the potential to corrupt a system and promote the theft of confidential information.
