Misleading Application
Risk Impact:
Systems Affected:
Symantec’s antivirus products contain an highly sensitive detection technology designed to detect entirely new risks without traditional signatures. This technology is aimed at detecting malicious software that has been intentionally mutated or morphed by attackers.

If one or more files on your computer have been classified as having a SONAR.RogueAV!gen20 risk, this indicates that the files have suspicious characteristics and therefore might contain a new or unknown risk. However, given the sensitive nature of this detection technology, it may occasionally identify non-malicious, legitimate software programs that also share these behavioral characteristics. Therefore, it is recommended that users manually check all files detected as SONAR.RogueAV!gen20 by Symantec antivirus products for potential misidentification, and submit any suspect files to Symantec Security Response for further analysis. For instructions on how to do this, read Submit Virus Samples.

In rare cases where a legitimate file has been misidentified and subsequently quarantined, your computer may behave abnormally or you may find that one or more applications no longer function as expected. In such rare situations, you should open the Quarantine in your Symantec antivirus product. From here, you may review the list of all files detected as SONAR.RogueAV!gen20 and, if you identify a potential misidentification, restore the file from quarantine and allow it to run normally.

It is possible to restore a file from quarantine to its previous location on your computer. This should only be done if you are certain that the file is not malicious. Symantec strongly recommend that you submit the file that was detected as SONAR.RogueAV!gen20 even if you choose to restore the file from quarantine.
