Is Malwarebytes scanning MS Outlook?

[AlainPaul]

Does Malwarebytes really and effectively able to scan Microsoft Outlook 16 OST and PST files?

Reason is that I am told by the Netwerk provider that my core email is infected and send Spam out. Running Malwarebytes on a 200MB files takes 2 seconds with no threat found, but by scanning a 3 TB file (containing hundreds of folders and thousands of files) it takes only 4 seconds again with no threat found.

Malwarebytes does not scan any email at all.

[David H. Lipman]

No @AlainPaul. 

Malwarebytes is not MAPI compliant, it does not scan email, and it does not target Microsoft email archive file formats nor email file disk files such as .EML and .MSG files.

If your email is sending out spam then it may not be "infected" but is a compromised email account.  For example you fell for a Microsoft Phish and supplied your credentials.  Thus the credential harvester can then use those credentials and use your account to spew spam.

Many thanks, that's what I thought as well, I tried McAfee, and he did report the same figures (time and no threat found) as MB.

But looking at Internet, I found that 'Yes' Malwarebytes was doing it! (Incl. Bing Chat function). And on another forum, they do say that for example Norton and AVG scan e-mails (OST and PST files) for viruses, spams!

Many thanks, my problem is that I contacted the provider who claims that my mail is sending spam and then block the mail account. I asked them if they could give me some info over the contaminated mail to avoid sending it again, but they can't tell me what is wrong. That's why I wanted to try to scan the files but no success. In the meantime, I updated all account passwords, but it took them three days to unblock the mail account. Any idea of a capable tool, S/W that can scan files like you mention above? I tried on the web, but no satisfactory answer found.

See hier the notification I received the same day that they blocked the account, therefore I was able to read it after the release of it:

"Because your e-mail address may have been misused, we have blocked your e-mail address as a precaution. This abuse can consist of, for example, sending spam, logging in frequently in a short period of time from various countries, automatically forwarding to a malicious e-mail address, etc."

That doesn't mean that a PC running MS Office Outlook is infected.

If your account is compromised then then one can use the Webmail interface to the account used and access your account and spew spam.

If you altered your credentials and have regained control and account access then you should be OK.

If you think your PC is infected, please read;  I'm infected - What do I do now?  then create a new post in;  Windows Malware Removal Help & Support

A trained Forum helper will assist you in checking out your PC and removing any malware that may exist.

Thanks again, fully understood. I have control of the mail by now (after updating the passwords). Then ran a full scan (McAfee Full protection) on the PC (six hours runtime in the background and no threat was found but like you say, I don't believe McAfee scans those Outlook files either. I will check these other postings.

[David H. Lipman]

I believe McAfee Anti Malware is MAPI compliant.

@AlainPaul Who is your email provider?

@AlainPaul Who is your email provider?

It's a Dutch provider (Ziggo/Vodafone) with good services (TV, Internet, and Phone) but with a bad service department (review scores of 1,8 out of 5), I am located in the Netherlands. 

[David H. Lipman]

Here is there Webmail interface

https://www.ziggo.nl/mail

One can have your credentials and use that to spew spam.

Have you viewed the Webmail Sent Folder?

[AlainPaul]

I did it with my mail, but not in webmail. Good point! I will check both again to figure out what was sent around the blocking.
