Hello, I believe I have a strong case that I have a malware infection that has repeatedly successfully discovered my debit card information when I'm making purchases online through my web browser using last pass to fill in the fields. I was not using a secure VPN line or private browsing or a browser sandbox explicitly, but was using the latest Mozilla Firefox. Even before the first attack, I had regularly used the free Avast, MalwareBytes, and CCleaner. Also, I had never had problems when I was doing online purchases using Bank of America as my bank in the past with the same tools, but when I switched to a local credit union (obviously smaller with less captital and spending power to make their servers "tighter") the problems soon began. They have performed multiple sessions of fraudulent debit card activity after reporting it (to bank) and cleaning with CCleaner, scanning deeply with Avast and Mal-wareBytes, still it happened again and again. Thank you in advance so much for all your help!
