Just installed latest full version of SpyBot Search & Destroy + AV (ver 2.8.67.0), along with SpyBot Anti-Beacon. Applied license routine. Running SpyBot for first time, an update of file signatures is required. Twice I have attempted to do this, but each time the software goes into a seemingly endless search routine that never finishes! After letting it run for about 12 hours in the background I had to finally cancel this routine. Because I couldn't complete the file signatures update, the software will not let me do any other operations it is designed for (such as a system scan or a rootkit scan). What can I do to correct this issue?
