I downloaded the setup file for SOS Online Backup.
When I opened the folder in Windows Explorer where I downloaded it to, KAV displayed a yellow File Anti-Virus Warning, saying it had detected in the setup file "Adware: not-a-virus:AdWare.Win32.Dm.v" with an Action "File contains Adware: 'not-a-virus:AdWare.Win32.Dm.v' and cannot be disinfected.
- Where does the phrase "not-a-virus" in this warning come from -- e.g., from the virus writer, from Kaspersky Lab, or from what I presume is a consortium of AV vendors?
- Does this warning simply mean that in fact it is not a virus but does contain adware?
- Why would I not have gotten a warning at the time of downloading? I've seen KAV do that with othe files (e.g., EICAR).
- I chose to install the program and saw no adware -- i.e., no ads. What kind of behavior or potential could KAV have seen in the file (i.e., other than ads it would display) that would lead it to display this warning?
