My computer is configured to receive automatic updates from Symantec,however I got suspicious this morning when the above executable was blocked by Nortons ? when I checked it said that there were some versions that were not genuine and harmful by the same name ! I then did a virus check on it which proved negative,so why was it treated as suspect and blocked by my firewall ?
In view of this will it be safe to release it onto my system ?
How can two files by the same name be so different in character ? ie one kosha and the other destructive.
