Question

opening rar files

Sep 2, 2016 6:19PM PDT

I recently scanned a rar file using Avast, and it said it was safe. However, when I tried to open it, it said that it was requesting to make changes to my PC. I'm using 7-zip to open the file. Should I be concerned?

Do you know where the file originated ?
Who sent it to you ?
Most apps will ask for permission , that's a given.....
You need to just be sure.....

While the contents scan safe they may not be safe when run.

I'll keep this short. No scanner today can detect if the apps inside the archive are not going to give warnings when run. We're not there yet.

And some apps must make changes to do what they do so depending on the app, it's OK or not.
