According to this: http://www.symantec.com/security_response/earthlink_writeup.jsp?docid=2014-080408-5614-99 Windows 9x/me is vulnerable to this exploit. Under the registry RUN keys, an entry is created where the name of the target is composed of encrypted javascript as well as using "non-ascii" characters (which renders the entry as invisible when viewed using standard tools such as regedit). Would msconfig show such entries - even if it just lists them on a separate blank line with nothing printed on it? Can Win-9x/me process javascript code present in the registry? Something else that has been said of this malware: "The non-ASCII trick is a tool Microsoft uses to hide its source code from being copied, but the feature was later cracked." So, how compatible is win-9x in terms of operability with this method of storing and running "mal-code" from the registry?
