Re: sp81969.exe



Thank you for posting in the HP Support forum @bubler


Sorry for the delay in the reply.


The file is clean. It is classified by these vendors by mistake - as you can see, the detection is not definite , it's heuristic type "Unsafe" / "High confidence" / "Suspicious" - it has no specific malware name.


It is detected by let's say "less reputable" vendors.


Antivirus have many different methods for detecting malicious code/viral and non-viral malicious code. Some are definitions for concrete detections. Others are behaviour analysis, heuristic analysis, intrustion prevention detection, etc... The effectiveness of heuristic analysis may be high re. catching new threats, but the effectiveness is fairly ~low regarding accuracy and the number of false positives/false detections. Here is more info about the AV heuristics >> https://en.wikipedia.org/wiki/Heuristic_analysis



Hope this helps!
