Antivirus Protection & Internet Security Software
Web threats and malware are malicious software programs designed to target users when they're online. They can appear in many forms, including viruses, spam, phishing, spyware, adware and other versions of cybercrime. Cybercriminals use malware to do everything from harass users to steal sensitive data.
Web-based threats – or online threats – are malware programs that can target you when you’re using the Internet. These browser-based threats include a range of malicious software programs that are designed to infect victims’ computers.
The main tool behind such browser-based infections is the exploit pack – which gives cybercriminals a route to infecting computers that either:
Do not have a security product installed
Contain a commonly used operating system or application that is vulnerable – because the user hasn’t applied the latest updates, or a new patch has yet to be issued by the software vendor
Cybercriminals will use almost any vulnerability – within an operating system (OS) or an application – in order to conduct an exploit-based attack. However, most cybercriminals will develop web threats that deliberately target some of the most common OSs and applications, including:
In 2012, the number of browser-based attacks was 1,595,587,670. On average, that means Kaspersky Lab products protected users against web threats more than 4.3 million times every day.
Kaspersky’s Internet security experts have identified the most active malicious software programs involved in web threats. The list includes the following types of online threats:
In 2014, Kaspersky Lab’s web antivirus detected 123,054,503 unique malicious objects: scripts, exploits, executable files, etc.
We identified the 20 malicious programs most actively involved in online attacks launched against computers in 2014. These 20 accounted for 95.8% of all online attacks.
