Considering the Eicar test file - it is NOT a virus. It is a completely innocent file that antivirus programs consider to be a virus (that’s how it was meant to) - but it is not.
So, it certainly does not spread, attack any other files, modifies avast settings or anything like that.
The only thing Eicar does when you start it is displaying the test string on the screen.
The warning noted above means that sometimes, inexperienced users may have problems deleting the file - the antivirus protection considers the file to be a virus and does not permit the user to access the file - maybe not even delete it. Some antiviruses may even freeze the system, such as if it was a real virus. So, it may be necessary to disable the resident protection temporarily (or something like that). But that’s all the warning is about. You really don’t have to worry about any damages caused by the “virus” behavior.
And, if you are experiencing such virus-like problems, they are not caused by eicar.
