Hello
I am new here.
I know how you send files that I find suspicious for avast?
Someone has already done?
Thanks ;D
First you should confirm the suspicion and that avast doesn’t detect them.
Check the suspect file/s at: VirusTotal - Multi engine on-line virus scanner and report the findings here in the topic, the URL in the Address bar of the VT results page.
Send a sample to avast if multiple detections at VirusTotal - Send the sample to virus@avast.com zipped and password protected with the password in email body, a link to this topic might help and undetected malware in the subject.
Or you can also add the file to the User Files (File, Add) section of the avast chest (if it isn’t already there) where it can do no harm and send it from there. A copy of the file/s will remain in the original location, so you will need to take further action and can remove/rename that.
Send it from the User Files section of the chest (select the file, right click, email to Alwil Software). It will be uploaded (not actually emailed) to avast when the next avast auto (or manual) update is done.
sorry but what it mean whit password virus
Put it in a zip then make a password for the zip for when avast! open then he type the password and check for it.
You can just send it to the chest and say email to alwil team and configure your letter for like as false positive or new malware
