star shaped icon has appeared on acer netbook desktop
I cannot remove this icon, nor access the internet. I assume this to be some form of malware? I have CCleaner and other malware tools on a usb stick, but when I insert it and navigate to the folder containing the software the programme icons are replaced by the same star symbol and I cannot access the software to run it. The OS is some variant of Linux, I don't know which though. Can anyone advise how to get to the Linux equivalent of safe mode, or better still, what this is and how to remove it? As you have probably gathered, I am new to Linux, so would appreciate any help that can be offered. Thanks in advance.
