However, there can be dangerous versions of Gup.exe file, too. Recently, we noticed some gup.exe versions uploaded to VirusTotal database, and it seems that there is an adware type program hiding behind this executable file name. This infection is recognized as CRDF.PUA.PUA.BundleLoader686044841, PUP.Optional.Bundler or ADW_BUNLOAD.SM. According to the report from VirusTotal, this file is a product of Glary Utilities Pro, and its full name is Glary Utilities Pro Setup. In other words, this file is used to install Glary Utilities Pro software, but unfortunately, it might suggest installing a couple of additional programs alongside the main one. Consequently, a failure to monitor setup settings can result in installation of several extra potentially unwanted programs (PUPs) on your PC, and such occurrences should be avoided. If you accidentally installed this piece of software from PCFreeSoft, consider removing it, because otherwise you might start experiencing annoying computer slowdowns, receiving ads and encountering other unpleasant issues right away. In such case, gup.exe removal is required. For that, you might want to use Reimage or similar software. You might also want to remove gup.exe manually, however, we strongly recommend you not to do so until you are 100% sure that you're dealing with a legitimate version of it.
The described executable file can be saved on your system after installing Notepad ++ or Glary Utilities Pro software, however, there might be other programs that use this name to disguise themselves as legitimate programs because gup.exe has quite a good reputation so far. However, if you are unsure about the gup.exe process running on your computer at the moment, or if you notice high gup.exe CPU usage, you might need to scan the file with anti-spyware or anti-malware software to check whether it is a trustworthy one. There's a possibility that you downloaded a wicked version of a certain software and it brought a corrupted gup.exe version into your system. Additionally, you may have installed it alongside some suspicious freeware after choosing Default or Standard settings for the setup. If you would like to opt out unwanted bundled items when installing freeware, choose Custom or Advanced settings and deselect suggested items manually.
Any malware can be named anything and gup.exe is not an exception.
