Technical Details

Note

Corporate or business environments are special exceptions, as they may require machines in the network to use a customized hosts file with multiple entries for a single IP address/block. These customized hosts files may inadvertently trigger this detection, as they appear to have the same characteristics as a trojanized file.

To prevent the possibility of a false positive or false alarm, customized hosts files should be screened for malicious entries; if all entries are legitimate, the file can then be excluded from subsequent scanning.
