AdWare.Win32.Advision.c not a Malware
Malware (short for MALicious softWARE) actively alters and/or damages your system, including the aforementioned browser resettings, rewrites of your configuration, entries into your Registry, system crashes, and more. Sometimes the line between malware and viruses is pretty blurred. The term is often used to cover the entire range of “hostile” software, including viruses, trojan horses, and worms. The author of Malware.org states that “the issue [of] whether a program is “malware” or not is in the mind of the person executing the code.” In order to get a deeper understanding, it would be best if you do more research and get to know the similarities and differences between these “ware” terms.
