Malware spotted from Steam file

[FighterSoldier]

I just got a notification from my antivirus that a malware has been spotted from a Steam file. Has anyone else's antivirus spot anything suspicious from Steam too or is it just me?

Edit: It is likely a false positive. My antivirus is Webroot, and I don't know if this is exclusive to Webroot, but it considers that Steam file as a threat.

Only a few times in a few foreign games. They were all false alarms though.

1: Which antivirus? There's dozens out there - many of which are shoddy/fake/hostile
2: What is the actual malware/message.

Now I'm running a VERY aggressive security suite
Steam is clean as clean as it gets - so pretty sure you have a false positive.

Unless you are modding or using 3rd party software that tampers with your steam client.

Interesting...

My antivirus said the threat has been removed though so maybe in my case it was a real malware.

You still have yet to identify who/what.
Might help if you fill in the blanks.

1. Webroot Security
2. Don't know exactly, but apparently it's from a Steam file, and now it says threat removed

You don't know...... no malware program out there would say you have something without saying what that something is.

It makes it hard to identify if you have a problem or not.
But alas - if steam is still working and your ok - then you can go about your gaming day.

Or you can keep digging - and maybe report to the Devs that they had a false positive - IF that's what that is.

AFAIK Steam hasn't really ever triggered a false positive in ages - but then I I'm running Security suites on Steroids - and they are extremely picky.

Yeah I don't know how to find that removed malware in Webroot, I'm trying to find out exactly what it is.

Strange that it didn't inform you what exactly it is removing and from where nor asked for permission to do it.
My inner cynism says, that it was most likely false positive and done solely to improve statistics.

I don't know much about webroot but most good antivirus programs have a log of actions taken. Also perhaps the virus file was "quarantined" (moved to a safe location where it can't do any harm, but it could be restored if you really needed that file... and it should tell you what the original location was)

Yeah I just ran a scan and I guess it got removed during the scan.

Open Webroot itself - check the systray to do that - most are hiding there (near your windows clock in the corner) - check for preferences/settings - anything that says logs history quarantine jar etc.
Those key words should point you to some kind of record or history as to what it did.

Out of curiosity - what kind of security suite?

You mean Zlib1.dll? i got the same as well. apparently its to compress and decompress files on steam maybe.

If it is that file and its part of the windows installation of steam then it "should" come back when you restart steam... perhaps triggering the antivirus again.
I have C:\Program Files (x86)\Steam\zlib1.dll and its 115,048 bytes(properties window of the file). Neither Norton360Premier or SystemMechanicPro is complaining about it.

Tried to check, appears no threat log saved, but I did find the execution history, trying to check there.

Yeah I got the notification after the Steam update I think.
