Soon I'll doing some purchases online using my mother's credit card. She's pretty sceptical about online shopping but I convinced her. She's not so sure about how secure it is and since I'm not so sure if I have some malware running on my PC, I want to be on the safe side and don't want to risk it. I already ran scans with Avast and Malware Bytes.
My question is, is there any easy and fast way I can isolate a part of my PC so I can purchase from there? Would a VM work in this case?
