Hi. I just wanted to let everyone know that if they get a fake email from fedex with a zip file attached that Avast Pro did not pick it up but Windows defender did. The strange thing is that I deleted the email (Thunderbird) , emptied the trash but Windows defender said that there was still a zip file trojan in the email and it could not delete it. I just deleted the whole inbox.
Lots of these in sirculation now…see reply #686

Spam is increasing everyday.
I know not to open attachments but what concerns me is that Avast did not pick it up . I then deleted the file , emptied the trash but only Windows Defender picked it up in my inbox. If I deleted the file why was it still there?
No single security application will detect everything, these things change very frequently and is a good reason to take a multi-level/application to security to improve overall detections. There are bound to be many occasions where avast detects things that WD doesn’t and that up to a point is because they are different.
Try compacting the folders in thunderbird as whatever was deleted is no different to deleting a file in windows, all that is actually deleted is the reference to the file in the file allocation table and mark that space as available. So it would take time for something to be allocated to that space over writing that old file.
I don’t use thundrbird, but on my email program deletion, emptying the deleted items folder and compacting the folders is the way I normally ensure an email is gone.
If you have done that and WD is still detecting something I would be concerned about the accuracy of the detection, second time round.
Hi Mctavish,
This matter has been submitted to avast virus team,

And the signatures has been updated also avast capable to detected.
This attacks method recently is very a lot of mailbox user received this kind of email. And please beware if you received some email which is you don’t know who is the sender, just please ignore them.
cheers,
That was really a strange virus. They used a fake email from FedEx for importing the virus. Hopefully, they solve it immediately so that everyone prevents it.
I have received an email for FedEx with an attached receipt which looks very suspicious (it’s an exe file)…
Avast free does not identify the downloaded zip as malicious (I scanned it)… but surely it is, else why would it contain an .exe file for a document…
why post in a topic fom 2010. :
upload the suspicious attchment to www.virustotal.com and test with 40+ malware scanners
post link to scan result here
