I suspect Trojan in my system

ArchyDice

On my computer installed Bitdefender Total Security. Recently New discovery, I never check the email section "SENT", checked today May 17 and found two empty emails sent to two different addresses which unknown to me and are not in my addresses lists, it was sent by the computer itself on April 17th and 18th. Despite the fact that I scanned computer at the end of April and the second time in May, the result showed that the system is clean. Scanned because the computer started behaving strangely but I didn't know about the emails sent. Now I have no doubt why my computer began to behave strangely and slowly, I have a Trojan from which your famous defense could not protect.

Hello.

First, create a log on your Windows device using BDsysLog, by following these steps:

Next, contact Bitdefender Consumer Support by e-mail here (scroll down to the bottom of the page):

with short description of the issue(s).

After that, you will get an automated reply by the Bitdefender Customer Care Team, with your ticket number.

Now, in reply to that automated reply, you can send the log file you already created in the first step.

Since you are all done, just wait for the support engineers to investigate your issue.

Also, you could perform a full system scan with these (or: with one of these) FREE malware removal tools:

Before making a post, I first checked myself or this is not a mistake. When the behavior of the computer become seemed suspicious to me, at this time I did not yet know that the computer sent emails by itself, I scanned the system with Bitdefender once in April and once in May, in addition, at the beginning of May I scanned it with Kaspersky one time scanner and today I scanned with F_Secure - all four scannes did not find a threat in my system.

By the way, I don't really trust F Secure because it did scan in 5 minutes at the same time Kaspersky and Bitdefender spend 6 hours +

@ArchyDice try downloading and running Malwarebytes. It has a small footprint so it can easily be uninstalled after a scan if you wanted, or saved as a second opinion scanner. Personally, if you're going to, I suggest using the free version on-demand once in a while, compared to the Premium version. Others here have differing opinions regarding that, but to each their own :) https://www.malwarebytes.com/solutions/virus-scanner
