I'm using CSC 3.0.172695.53
windows 7 64-bit, microsoft security essential + comodo firewall
CSC is just keep loading for more than 4 hours !!!. Although many times I see CSC downloading definition (by pop up). But it seems can't be used. I think it's because it need long time to search the junk. But it seems not normal if it keeps like that for 4 hours. It compared with many freeware out there with searching just couple of minutes. CSC search capability + database can't be longer than 4 hours long just for finding junk.
This issue will be fixed in the next releases.
Thank you for your support.
