Question Antivirus blocked Trojan need help.

[Mistince]

Hello, 2 days ago I received a notification from my antivirus saying that it quarantined a Trojan from AppData\Local\Packages\microsoft.windowscommunicationsapps_8wekyb3d8bbwe\LocalState\Files\S0\4. I believe that this is a location that has to do with my outlook/mail on my PC but I’m not sure. I’m confused on how this could have happened since I don’t open go anything sketchy nor open or download anything in my email. After the Trojan was deleted from my PC via antivirus, ran multiple full system scans on different softwares and found nothing. Could there be anything lingering even though that file was never opened before it was deleted or am stressing over nothing?

Thank you.

Do you do online calendar or anything that might have your e-mail client periodically checking the internet, outside fetching mail ?
There are always free alternatives like Thunderbird and Seamonkey (New Netscape full suite).

I do not, do you think it’s a good idea to remove that email from my personal computer, since I do get quite a bit of spam since that email is so old.

You have settings on setting in Outlook, you can set to dump spam daily or weekly or monthly. Have some setting to remove it, aka delete. You can set trash the same way, mail that you deleted, gets permanently gone in 1 day or 1 week or 1 month. Browser same way, all cookies and tracers, gone when you shut down browser.
Inbox can be compacted and you can go through and keep e-mails you want in a custom folder (forever folder), all but recent year, six months, 1 month deleted from both inbox and sent. Maintenance is up to you.
Virus can only get in by way of Webpage or E-mail, otherwise it can only happen if your PC is directly accessed remotely. Not likely for private individuals, but not outside the realm of possibility.
By private individuals I mean not Corporate or Government people.

Perfect ok, I’ll definitely be setting that up for my E-mail. One other thing, that location that my AV quarantined the Trojan from, is that just temp files where the email stores anattachments even though they have never been opened? I say that because In that folder there was also old photos and PDFs that I’ve never downloaded but we’re on that E-mail. I also think it could’ve been a false positive detection.
