I was testing Comodo Rescue Disk today, and I dont know if this is actually a bug.
Because WiFi is not supported, and my router not having any port for wired connections, I tried to import the virus database from local COMODO installation (/mnt/C).
Perhaps someone else can try to reproduce it:
Once in COMODO RESCUE DISK, open CCE.
Go to TOOLS > IMPORT VIRUS DATABASE.
Then, import the latest bases.cav file.
CCE in Comodo Rescue Disk has a bases.cav file size of around 4 or 7 KB.
After doing the above procedure, the file remained with the same size.
I manually deleted the original file, copied the new file (+140 MB) and changed permissions:
There is no way I could verify if doing this procedure manually, would allow CCE to accept the bases.cav file.
CCE in Comodo Rescue Disk should inform the version of the database being used in ABOUT and in LOGS.
CCE 2.4 works fine with this import feature.
