Kaspersky has false positives by downgrading a virus as PUA (potentially unwanted software).
I have personally been infected with these viruses on my computer, so I know that they are not PUA but instead they are a virus. They made explorer.exe and searchapp.exe (called searchui.exe in earlier windows versions) crash on my computer nearly every day. It degraded the speed and performance of my computer and caused third party software crash to crash much more often.
I have no idea how these viruses got onto my computer. I did not download them and I was the only person within the physical proximity of my computer. Maybe a third party software exploit was used to download them (eg. an itunes exploit). What I find mysterious is how they both have a digital signature which allows them to evade antivirus detection.
I uploaded the files to Kaspersky Open TIP today. (threat intelligence portal)
It should not have the orange caution triangle badge saying “adware and other” but it should instead have the red warning square badge saying “malware”.
