Hello ,
I have three Windows Command Script files which, when I open them , cmd appears.
I'm a bit suspicious of them, they're just 1 or 2KB in size.
Windows Defender scans and nothing found , additional scanning with the free Malwarebytes.
How I can be sure about them ?

Thank you
 
As sugeggested, if you don't know what these scripts will do. why do you wan to run it? MS scanning tools not necessarily will know what the script will do to the system
I didn’t install the software myself—this is the first time I’ve encountered this situation.

The software was activated using a CMD script.

Since then, I haven’t been online to find a solution, other than reinstalling Windows or throwing away the hard disk.😓
So why I ask for AV and firewall and scanning tools in another post is due to this reason. Maybe scanning with some reputable software like malwarebytes , norton power eraser , sophos , dr web cureit , at least give calm feeling to me ! It's hard for me to hear from experts to reinstall windows or change harddisk .
😔
 
So if installing multiple scanning programs—like the ones I mentioned, plus tools like IObit Malware Fighter and F-Secure Online Scanner etc....—doesn't harm the system, then I delete them after running the scans. That way, I can feel more confident and at ease about the safety of my operating system
 
BZZZZZTTTTTT!

That is not valid software, or a valid activation method!

What specific software, and where did you get this?

Yep, almost no legit software will activate this way. If it's legit, there is no reason not to share the name and the site link.
