PUP.GoforFiles is a Potentially Unwanted Program with file-finding search features. Although PUP.GoforFiles's features appear to be in working condition, malware researchers also have found numerous issues with PUP.GoforFiles's website, Goforfiles.com, and even some invasive functions in PUP.GoforFiles that are reminiscent of the threat-downloading attacks of some Trojans. While you may find some use finding files with PUP.GoforFiles, PUP.GoforFiles should be treated as a potentially hostile program until further information is available, and, for safety's sake, uninstalling PUP.GoforFiles should be done with the same procedures you'd use to remove a Trojan.

When Going for Files Gets You More Than You Wanted

PUP.GoforFiles, a potential variant of YourFileDownloader, is a 'search engine' that specializes in finding files for download. This part of its feature set is, as far as malware experts can determine, functional, but PUP.GoforFiles also has several other functions that force its current classification as a Potentially Unwanted Program. PUP.GoforFiles often installs additional software, including adware (programs that generate browser advertisements) and browser hijackers (programs that redirect you to unwanted sites). PUP.GoforFiles updates itself automatically, which is a fairly substantial security issue. Finally, PUP.GoforFiles exploits the Windows Task Scheduler to allow itself to start automatically with Windows.

Because its software-installing features are both invasive and unnecessarily broad, some PC security companies have gone so far as to categorize PUP.GoforFiles as a Trojan downloader. PUP.GoforFiles may be detected by common aliases, including Tool.DownLoader.52, Win32/YourFileDownloader.B, Win32:Adware-AHK [PUP] and Skodna.Generic_c.CR. So far, malware researchers haven't identified any incidents of PUP.GoforFiles installing confirmed threats onto vulnerable computers, but PUP.GoforFiles's mere presence should be treated as a security concern.

Letting PUP.GoforFiles Go Off into the Horizon

It is very easy to understand that installing software that a good third of all the major anti-virus companies rate as a threat is a bad idea. However, there are no indications of this seedy history on the PUP.GoforFiles program's website, which does its level best to convince you that its software is useful. If anything, PUP.GoforFiles exemplifies how research into the software you choose to install continues to be critical and can't be replaced by believing what a site's marketing says about its product features.

PUP.GoforFiles does give its users uninstallation instruction on its site. However, considering its penchant for installing additional PUPs, malware researchers find deleting PUP.GoforFiles most reliable with third-party solutions, rather than hoping that PUP.GoforFiles will remove everything that PUP.GoforFiles installed. Unfortunately, a majority of PC security products have yet to develop database entries for PUP.GoforFiles, which can best be detected by making sure that all anti-malware products are as updated as possible.
