My friend owns a Mac with Microsoft Office installed and executed (with macros enabled) a trojan horse, AFAIK a W97M/Downloader variant. By fetching some information from the wild, that trojan usually tries to install some executable and/or script file specifically crafted for a Windows OS.
My questions are:
- is it correct to assume that this kind of threat is mitigated by being run on a Mac OS?
- Is it enough to say him to just remove the doc file?
- Any suggenstion for handling this kind of malware?
I'd like to avoid installing a malware removal tool as I have absolutely no experience and I'm fearing of worsening the situation.
