ESET Online Virus Scan
is one of the more effective online scanners. However, ESET's detection rate is high and can include legitimate files which it considers suspicious
, a Risk Tool
, Hacking Tool
, Potentially Unwanted Program
, a possible threat
or even Malware (virus/trojan)
, when that is not always the case. As such you have to be careful what you choose to remove.
A Potentially Unwanted Program (PUP)
is a very broad threat category which can encompass any number of different programs to include those which are benign as well as problematic. Thus, this type of detection does not always necessarily mean the file is malicious or a bad program. PUPs in and of themselves are not always bad...many are generally known, non-malicious but unwanted software usually containing Adware
with other free third-party software to include toolbars, add-ons/plug-ins and browser extensions. PUPs are considered unwanted because they can cause undesirable system performance or other problems and are sometimes installed without the user's consent since they are often included when downloading legitimate programs. PUPs may also be defined somewhat differently by various security vendors and may or may not be detected/removed based on that definition
. That fact adds to confusion and a lot of complaints from end users asking why a detection was not made on a particular file (program) they are having issues with.
Previously, Malwarebytes Anti-Malware detected only PUPs that were considered mostly harmful and deceiving but they revised their policy
, taking a more aggressive approach to include PUPs that most users found annoying or misleading. PUPs may be defined somewhat differently by various security vendors. This is what Malwarebytes has to say:
* What are the 'PUP' detections, are they threats and should they be deleted?
* Malwarebytes Adopts Aggressive PUP Policy
* Malwarebytes: Potentially Unwanted Miners – Toolbar Peddlers Use Your System To Make Bitcoin Mining
* The complexity of finding, preventing, and cleanup from malware
If you recognize the PUP detection(s) as belonging to a program you installed and/or want to keep, you can add those items to the exclusion or ignore list
(by right-clicking) so they will not show in future scans. If you don't recognize the detection(s), then you can remove them.
