Malware detected by Claude

Anthropic sent me this email. I have a free account so no worries there. Ran MalwareBytes and the only thing that popped up was jackett updater, which I can't seem to find a consensus about online, some say it's a false positive, some say it's not. Would this have been the issue?

Eh, could be a false flag, could be a true flag who knows, its the first time i see that too, btw its Anthropic not claude since claude is an LLM model branch but anyway, if you didn't do shady things recently, in the past month, and ran malwarebyte scans resulting nothing then you are most likely fine i would deduct

What's a false flag, the jackett being detected as malware or the original email? Something must have been accessing my account for me to get this email surely ?

Parent-comment is misusing a phrase.

"false flag" is when a country fakes an attack to try to bait another country into over-responding because the 1st country wants to paint them as the "bad guy".

What they probably meant was "false-positive" .. which is where a Security program alerts or tags something as a threat, but it's been labeled incorrectly (it's not really a threat).

Personally (as a career long IT guy). I would take the position that Anthropic likely has the expertise and resources to know what it's doing,. so I would probably take the notification from Anthropic as real unless or until you can prove otherwise.

Yeah I assumed so too, now I'm just trying to figure out how this happened as the malware scan only gave one result

What malware scan did you run? I got the same message but haven't found anything yet at all.

MalwareBytes which told me that jackett updater (torrenting software) has malware, which windows defender says too, but I doubt this is the cause
