Since a few days many of emails in my inbox get flagged as infected. I'm using Mozilla Thunderbird 2.0.0.17.
It is always the same type of alleged malware (Trojan.Script.5758) and it is always a short text-only email with attached jpg-file/s
When I check the attached jpg's after saving them to my desktop they appear as clean. Of course I also checked with www.virustotal.com where they also get flagged as clean.
After some laboring I found this out:
- my jpg's are clean
- Bitdefender gets probably confused by the base64-encoding which is applied to binary attachments by Mozilla Thunderbird
attached is one affected jpg and the same jpg within an email as well
