Hello!
Recently, I downloaded something to my computer, (can't remember what) and I have since then permanently deleted the files. Before, I was using McAfee, and it didn't detect anything. However, a few days later, nearly all of my accounts have been stolen, most of which I was able to recover. I promptly installed Malwarebytes, ran several scans and seemingly got rid of any trace of the virus. Today, however, I got a critical security alert from Google saying there was suspicious activity on my computer, and it has since logged it out of Google. However, I got the alert at 4 AM while I was asleep and my computer was turned off.
What should I do? Thank you in advance.
