zShowHelp is endorsed as valuable browser extension that purports to encrypt the user’s online searches, which ensures no data leakage that translates into a more private browsing experience. Based on this attractive feature alone, users can easily be tricked by the potentially unwanted program (PUP) and this is how malware researchers categorized zShowHelp.

Same with older version as ZRunStop and zSuperUpdate, zShowHelp normally gets into the computer in an unusual and unexpected way. It has been discovered that this malicious browser extension takes advantage of the malicious advertising player to spread all over the world. Web pages of zShowHelp pop-up ads with assertiveness on random websites which are generally in the category of software download, hacking, and gaming sites.

Software bundling technology is also used to disseminate zShowHelp. Thanks to this method, the malevolent extension is inserted into various freeware or shareware. Making it available at a number of file-sharing sites increases the odds of reaching a number of computer users. They negligently install the freeware without realizing that zShowHelp can also get on board because of lack of knowledge in running a ‘Custom’ installation.
