: This could imply that the detection was made locally (on your device) without referencing a cloud-based detection system. Some antivirus solutions use cloud-based scanning to compare files against a vast database of known threats. A "no cloud" notation might suggest that the detection was based on local heuristics or a locally stored database.
Most trojans, including those flagged as trojanheur02252123 , are distributed via keygens, patches, and cracks. If you must test suspicious files, use a virtual machine. gridinsoft no cloud trojanheur02252123 upd
