Vobfus.A is a worm which establishes connections with Chinese websites, from which it attempts to download files, among them, some belonging to an adware program.
In order to do so, it loads the character packets belonging to Japanese, Chinese and Korean, so that the system could interpret these languages. This could allow the worm to download malicious files from websites in any of these languages without any problem and even redirect users to malicious websites.
