Trojan found on Mac by Avast?

Aleks is not malware. Avast made a mistake.

If Avast! deleted it, then it should be gone. However, that does not address where it came from. You should check the log carefully for any listing of where Avast! found it, and figure out what additional preventive safeguards you may want to implement. Most dangers from Trojans or other viruses like that won't do anything to a Mac system unless you somehow double-click on it and run it.

Most are actually Windows infectors carried to you via email or download of some sort.

Aleks is not a trojan, it is AI software produced by the University of New York and the University of California (Irvine)

Avast itself is the problem.

I have too 4 Trojan virus and it found the avast. Is nothing because it's Windows virus it can't effect your Mac, I take the apple support it's sure .

BUT

If you have windows is very dangerous for your windows and the mac cause this virus close your firewall protection and then delete your user(s)

NOTE

You can remove it ONLY is you are Windows user on Mac if it go on System if it is just an file delete it.

Perhaps you should post in your native language and let us try to translate, I really can't make sense of your post.

Avast has serious, long-term problems with false positives. I would recommend uninstalling it.

This particular detection is most likely an error, as Csound1 has pointed out. However, there's no guarantee that the file is actually related to Aleks just because it has that in the name. Malware commonly uses tricks like naming itself after legit software.

Because of this, I'd ask what specific trojan this was identified as. I would also ask you to locate that file and upload it to VirusTotal:

https://www.virustotal.com

VirusTotal will scan the file with a large number of anti-virus engines and give you the results. Post a link to the results page here.

After you have resolved this situation and removed Avast, I would recommend that you see my Mac Malware Guide. If you decide that you still want to have anti-virus software at that point, use one of the ones recommended there.

The file referred to ( "alekspack10.jar" ) is a legitimate part of the Aleks software, but that does not prove that this is the actual file, or some malware masquerading as the file.

Yeah, you're probably right, but there's always a chance it's not legit. Slim, but possible.

Yes, it's possible, so that should be taken into consideration.

I already had deleted it before posting this but I can check to see if I can still find the file.

If you have backups, you might be able to find it there. (If you don't, you should drop everything you're doing and focus on starting a backup system. Literally.)

I'd also point out that the knee-jerk reaction that causes people to immediately delete things detected as malware is a bad one. You should NEVER allow anti-virus software to immediately delete something that it determines is malicious, nor should you delete it yourself until you have done your homework.

Deleting "infected" files automatically is bad for several reasons:

* It could be a false positive, and deleting it could destroy valuable data, damage an application or damage your system.

* If it's actually malicious, it could be a new variant of something else, and ought to be submitted to the security community (via VirusTotal) so they can do a better job of keeping you safe.

* If it's actually Mac malware, you need to know exactly what it is so that you can find out more about how to get rid of it. Some Mac malware can be removed fairly easily, but other malware should never be removed by any method other than erasing the hard drive and starting fresh.

I'm not sure why you say anything sounded angry... ?
