Greatzip is an application that works as a file compression tool. The information provided on its official website greatzip.com tells users that it is a simple, but yet powerful file compressor. Research has shown that it is based on 7-zip, a well-known open source software working as a free file archiver, so it shares similarities with this tool too. Users are told that this application can easily zip and unzip files, enable users to secure files with the AES encryption, and, finally, zip large files for sending them via email. Since Greatzip is based on the engine of 7-zip, it also supports the following popular file types: .zip, .rar, .7z, .ace, .arj, .arc, .kgb, and others, which makes it quite a powerful tool. Although this information is taken from its official website, it is not only a pretty description. Specialists at 411-spyware.com say that Greatzip really works quite well after carrying thorough research about it. That is, it performs the main activity – compresses and extracts files. Despite those useful features it has, it is far from a trustworthy application, specialists say. They call it a potentially unwanted program instead because it has several features decent programs should not have. Specifically speaking, researchers do not like how this program is distributed. Second, they have noticed that it is closely associated with Open Downloader Manager, which is also known to be a potentially unwanted program.
Greatzip is the most prevalent in the United States; however, any user can download it from its official website greatzip.com. There are some users out there who download and install this application on their computers because they believe that it is a powerful file compressor. It really has a number of advantages listed on its official website, for example, users are told that they could zip and unzip files with its help easily and quickly, so we are not surprised at all that some users download it willingly from the web. Of course, not all the users are glad to see this piece of software on their computers. In fact, some of them do not even know that they have this application on their computers, which suggests that it can enter computers without the user’s knowledge as well. Researchers at 411-spyware.com have carried out research to find out whether it is true or not. The study has revealed that Greatzip might also be promoted by malicious pop-up advertisements, e.g. http://greatzip.com/adv1/site.php?ID=adcmscrr&sub=adcmscrr&subid=66076-8090cb.com&S2=1486754648807_1486754648101_249_33511_9746170_1. Users end up with the potentially unwanted application on their computers after clicking on such a pop-up advertisement once, no matter they know that they click on the ad or they do that incidentally. Your Download Software Manager promoting Greatzip could have installed additional software on your PC too, so if you remember clicking on the Download Now button located on some kind of advertisement recently, it is very likely that you have other untrustworthy applications developed by third parties active on your computer too.
If you are reading this article from the beginning, you must know that the main drawback of Greatzip is that it might illegally enter computers. Sadly, it is not its only disadvantage. Researchers have noticed that this application connects to the Internet without permission as well, so if you do not erase it from your PC soon, it will use your Internet connection from time to time. Nobody knows why it does that, but specialists suspect that it communicates with its C&C server. It might also collect information about users and then send the gathered data to its main server too. It will no longer bother you only if you uninstall it, so go to get rid of it as soon as possible.
Users who have not willingly downloaded and installed Greatzip on their PCs or have found this piece of software undesirable must go to remove this potentially unwanted program from their PCs as soon as possible. It can be erased through Control Panel, so its removal should not be very complicated. Do not forget to take care of all other untrustworthy applications actively working on your PC after getting rid of this PUP – they could have entered your system together with Greatzip. The easiest way to find and get rid of them all is to perform a full system scan with a reputable malware remover.
