Cannot copy/paste Bases.cav Ver(3.9.95478.509 x32)

I’m getting the “Antivirus engine is not initialized” error when I try to update or scan using Comodo. I think its an issue with the Bases.cav file, since I don’t have one in my Scanner folder. When I try to copy one from the Repair folder, I get a “data error (cyclic redundancy check)” error. I get this even in Safe Mode. This was just installed for the first time, on a fresh install of XP Pro SP3. I have used the Diagnostics tool which found an error, but could not repair said error.

Thanks in advance guys.

Getting a crc error means that the data is corrupted. Try uninstalling CIS and reboot. Then make sure the CIS folder under Program Files is totally gone and install CIS again.

Did this help?
