I rid myself of KSC. Never again. And never Kaspersky.
Two evenings ago I noticed a drop in responsiveness on my laptop. A quick investigation showed that KSC has maxed out my wi-fi bandwidth, uploading who knows what to who knows where.
I watched for 5 minutes while the upload activity continued at full bandwidth. Instinctively I disabled KSC, but that had no effect on the transfer, so I went to "airplane mode".
KSC never asked my permission to upload, and given the bandwidth usage, this must have been a sizeable transfer.
I'm now back to WD (VS still present) after uninstalling KSC and manually removing file and registry debris it left behind, as well as a Kaspersky file tucked away on each partition under System Volume Information.
Enough is enough. I don't care how effective Kaspersky products are at defeating malware when they act in this unfortunate manner.
For those using KSC, my tweak is... use KSC's uninstaller, augmented by Revo Uninstaller, Everything, Registrar Registry Manager, and some manual cleanup. Peace. Out.
