My Work Laptop Started Sending Emails I Didn’t Write—Could It Be a Virus or Someone Else Using It?

Lately, a few coworkers mentioned getting weird emails from my work address, but I never sent them. These emails are really out of character - some have links and strange attachments, which makes me worried. I mostly use my laptop for remote meetings and occasional reports, and I keep it locked when I step away. I haven’t installed any new software recently, but I did click a link from a sketchy newsletter last week. I ran a quick antivirus scan that didn’t find anything, and I changed my email password just to be safe. Still, I’m not sure if the problem is malware on my laptop or if someone else somehow got access to my account remotely. I don’t want to cause a big fuss at work if it’s a false alarm, but I also don’t want to risk company info or my reputation. Has anyone dealt with emails being sent without their knowledge from a work device? What are the best steps to figure out if it’s a virus on my laptop versus someone hacking into my email? Also, are there ways to check what devices are logged into my account that I might have missed?
