The latest updates (going back the past 2 months at least for me) to SMplayer portable app are triggering "false positive" reports in Kaspersky AV.
The Kaspersky warning claims that app can be used for malicious purposes and places the Kaspersky AV Suite into it's "warning mode" (non-green AV GUI background) until the portable app is either (1) removed from the PC; or (2) an exclusion/exception is entered into Kaspersky.
The Kaspersky AV scanner provides no other virus indications other than to nag me about SMplayer potentially being used for malicious purposes.
Perhaps this issue is entirely on Kaspersky; I think it is. Thought I would pass along this experience.
(1) My Kaspersky software is about to expire and it will be replaced with something different.
(2) None of my other portable apps from PortableApps.com cause any trouble or warnings for Kaspersky AV.
That's not a virus detection. That's Kaspersky flagging it as a Potentially Unwanted Program (PUP). If you want SMPlayer, you can ignore it. I you don't, you can remove it.
Sometimes, the impossible can become possible, if you're awesome!
