Java:Malware-gen [Trj] popup

Viruses and worms
1

I am getting “Java:Malware-gen [Trj]” warning. Avast is showing one by one endlessly. It is a big pain. It is related to my Thunderbird. No idea what I can do about it. Tried different anti-malware soft which did not help.

Here you can find screenshots of warning examples:

1.Make sure detected mail is deleted, you may need to access your mail account from webmail and delete there

  1. Clear cache in Thunderbird mail client and reboot

It’s telling you that you have an email that contains JAVA scripts/Malware generating scripts/ Trojan.
Pondus is correct, open you email thru webmail or website and delete it(the one from the 2nd screenshot).

Bonjour / Hi
I have exactly the same issue here.
I get a message from avast, which popup every 15seconds that it found a problem on one email on my outlook file.
I searched on my webmail to find the problematic email, but I’m not able to find it anywhere (I looked deeply I promise)

Avast said to run the complete test, I made it 10 times. But message continue to showing up.
Is someone who can help me please please please ?

Try clear cache in your mail client and reboot

Merci Pondus,
I did the clearing cache, following this instruction : https://www.grok.lsu.edu/article.aspx?articleid=17321

I restarted my computer.
Afterthat I restarted Outlook then the crazy popup cames back… :cry:

Any other idea ?

Any other idea ?
Your screenshot say it is moved to chest / quarantine, and you don't find it in webmail, then in my mind this indicate a sync problem that should be cleared if you empty cache .... have worked for others

Don’t know if that will do anything more than what you’ve already accomplished.
I personally don’t use outlook so have no way of testing it.

Thanks to Pondus. It makes a sense and it is a possible reason.

hi bro

     I found this problem like you all so the Avast show "Threat secured" We'vd moved Main$1656_.class to your virus chest because it was infected with Java:Malware-gen[Trj].

when I click on detail it will show
File path : Incoming email ‘FW:swift copy’ From"Monica Costia" monica_costia8827@gmail.com

Process : C:\Program Files\Microsoft Office\Office15\outlook.exe
deteted by : Mail shield
Status : moved to virus chest

but this warning will open in 15 sec. So how can I disable this warning and I need to make sure
Avast can kill this Java:Malware or not. I use malwarebyte for scan and use Avast internet secure with full scan but not found this Malware in my computer.

buy Avast show warning in 15 sec. so please advised how to fix ?

thank you
