Hey all. I have a heavily infected system at my workplace. The system is a isolated setup, with no outside internet access. LAN only.

Symptom : Random IE Windows popping up, but theres no internet access so I can't see where it is navigating to

Symptom : Windows Task Scheduler has 1-3 tasks that automatically re populated calling a .exe file in System32 or temp

Symptom : Random Crashes, lock ups forcing a restart

I have tried Hijack this, and Maleware bytes. Going to try Glasswire to see what the files are trying to communicate with.

I'll post Hijack logs and M&B Logs in a few minutes

MXHNDFYSYS.exe is starting every restart

Hi, unfortunately I cannot give you advice for I am in training, and you will need to wait for a malware removal specialist. However, I can get you started and reduce the amount of time taken to solve this problem.

Before we start please note the following:

• Analysis and research take some time, so please be patient. If your helper doesn’t respond for more than 24 hours, PM them.
  


• Please follow their instructions exactly as they are posted and do not run any tools on your own.
  


• Stay with them to the very end, the absence of symptoms doesn't mean that your machine is fully operational.
  


• They can't foresee everything, so if anything unexpected happens, please stop and inform them.
  


• If you have any questions, please don't hesitate to ask your helper.

Please don't take advice from this guy, he tried to spread his RAT here... He is also not experienced and will most likely leave your system in a worse condition then it already was.

Edit : I have just Identifed the threat as the JSAgent Trojan, Best removal strategy ?

JSAgent Trojan is a generic detection name for any JavaScript based trojan. This is no real identification, it can mean almost everything.
Run FRST if you want to get help (see instructions above by YekiM). HJT is outdated and not sufficient anymore to deal with the threats today.

I ran a Avast Bootscan on this machine, its listed as "Clean" , but keep in mind this is inside a closed network, all the machines will usually get the virus's / random ass DLL files back in a few hours

[Knautschtabak]

Acsriot, please disconnect every infected machine from the network or they will reinfect each other. You can put them back when they are clean.
The machine you made the logs from looks clean, there are just malicious startup entries left, whose files are missing.
