Malware (composed of the words maliciousness and software) are programs that have been developed to perform undesirable functions causing harm to the user. In the beginning, the objective of malware was to irritate individuals, but this has quickly expanded into systematic spying and stealing of personal information. The victims are no longer just individuals but also large organizations such as banks. The extent of the use of malware has risen sharply in recent years and is now a drastic factor in cybercrime.
The term malware encompasses many types of malicious programs.
Operators of malware take advantage of the attractiveness of search engines. They will attempt to create webpages that rank well in the search results of search engines in order to direct users specifically to the malware. The danger is that your computer will be automatically infected with the malware when selecting the search result. The provision of such links in the SERPs is also called SEO attack. Google tries to stop websites which endanger users through malware, and relentlessly search for such.
Moreover, malware can be distributed through malvertising. These are banners which contain malicious code to infect other computers.
Since March 2013, Google is providing special help pages for website operators who are victims of a hacker attack. They contain a step by step explanation of what to do to restore your website after an attack. Google gives tips on how to avoid hackers in the Webmaster Blog on the topic of hacking.
