Dr.Web

Dr.Web is a Russian anti-malware company and the name of its flagship software suite. First released in 1992, it became the first anti-virus service in Russia. The company also offers anti-spam solutions and is used by Yandex, Russia's biggest search provider, to scan e-mail attachments. There is also an add-on for all major browsers which checks links with the online version of Dr Web. Dr.Web has withdrawn from AV tests such as Virus Bulletin VB100% around 2008 stating that they no longer represent the ability to counteract contemporary malware threats.
