I regularly get VSE events signalling detection of some malware/virus in image files (e.g. "dcimages/1lcdb0.gif"). Usually I get a dozen similar events in one shot from the same PC and then nothing for several days. Typically, the events note "action taken : none - handled : yes".
I tend to believe these are false positive, but still, I'm wondering why VSE signals this, why it does nothing (no delete or quarantine) and why it is OK to do nothing about this.
