False positive system.dll file detection?


Recommended Posts

Hello and greetings, currently running a offline scan with windows defender atm as I type this. I was doing a random scan and it mentions system.dll was detected. out of confusion, I did just update malwarebytes. I will try to scan with a few more processes here in a few, but I wanted to see if this was a new thing popping up or mentioned from anyone else here. Thank you.

but malwarebytes is the only one noticing it.

You need to turn off rootkit scanning.

Given you had rootkit scanning enabled, that might be the reason since this reads user mode with kernel-mode version and when a file is in use at the time, it might see a difference here. This doesn't mean it's a rootkit though. This might just happen when the file is in use. Sometimes this also gives unpredictable results as that engine works slightly different. This is exactly why rootkit scanning is disabled by default when you install Malwarebytes. Also, our current engines are powerful enough already to deal with rootkits even when rootkit scanning is disabled.

Rootkit scanning is not enabled by default. You may want to disable that unless you think you have a rootkit infection.

Rootkit scanning is really aggressive and does ignore some whitelisting which can result in false positives. 
If you decide to keep rootkit scanning on, just be aware of the possibility of false positives.

ok, so nothing to really worry about? I installed dr web trial for now to see if it notices anything going on as well.

Hello,

It is an odd place for that file and not a common location for it at all. Probably from extracting an installer to the root of your system drive.
Usually it lives in whatever %programfiles% directories that use it, in randomish named temp directories when the installer is run and contents extracted, and buried in several Assembly directories if they require specific versions of that dll. So there will be multiple versions all over the system. Just rarely ever in root of system drive.
If you know what put it there then you can have MBAM ignore it. It is a super old rule detecting it by path.

Not malicious in itself, so nothing to worry about.

sorry for the crude snapshot, i noticed a older program i used msi afterburner was giving me a warning, so i removed it, then this popped up scanning with dr web  doing a offline scan.

I swapped to fancontrol as msi afterburner over time began to fizzle out a bit, but forgotten to uninstall it anyway. uninstalling msi afterburtner caused this to happen?

sorry my anxiety is highly up at the moment.

You need to take a breath and stop scanning with every program you can get your hands on.

You are going to make things worse for both your computer and your mental health.

Sorry, is this file considered malware? I am learning about alot of this more recently. the file date is 2/16/2015, and is around 103kb.

Probably not considering the software it is related to.

Ok thank you and sorry again, I will try to do a clean update of windows, and call it a day. i noticed my c drive was losing more space over time, I wanted to try to figure out why suddenly it was edging closer to 6.16 out of 111GB. Then this rabbit hole. haha. I usually have a routine of updating my software

111 gigs is usually close to what a 120 gig formats to. That is small for running Windows.

looks like my windows borked. :( I am in tears atm from all of this, sorry again for all of this drama from me. all of my hardwork into what i do is now possibly done, it tells me a "grub" error as i boot up into the drive. this was a donation from my brother. he used to use linux, and for me to see this error means windows 10 pro borked.

I am sorry you have more issues now. I did warn you.

Do you have another computer you could build a Windows USB with?

looks like it wont recover anything from the drive, so i might have to do a fresh install in this instance. sadly.

There are ways to use a Linux boot disk but I do not know your skill level.
