Hi. Kaspersky Internet Security did not inform me that it’s File Anti-Virus subsystem was making an interference in the installation of Oracle_VM_VirtualBox_Extension_Pack-6.0.20-137117. I’m talking about the Notification and Logging (Reports) subsystems. I’m not talking about the File Anti-Virus subsystem. (Whether my setup was problematic, or VirtualBox did it non-standard, or Kaspersky File Anti-Virus made a wrong interference, can be target of another discussion. For the record, I tested disabling Kaspersky File Anti-Virus thanks to a VirtualBox forum user who noted his experience with a McAfee file anti-virus!) Of course it would be solved much sooner and easier if it did tell me about the interference. I’d like to prevent a future confusion. So: Is it possible that Kaspersky File Anti-Virus makes an interference that disappears when it’s disabled without actually trying to block something ? I’m trying to first consider other possible explanations for the absence of the log. Are any and all possible blockages through a decision making system? What can I do to make sure I won’t miss any blocking notifications? I’ve always tried to make Kaspersky more verbose about what it blocks (and also get rid of non-important distracting notifications), but now I looked at the notification settings to make sure, and saw it saying “46 hidden notifications” (or something like that) and I clicked “Reset all hidden notifications”, but again, the installation fails when File Anti-Virus is enabled and there is no notification or log.
