is it possible for a malware breaching the firewall rule without getting administrator access in Win 10 / Win 11. Using cracked / suspicious / malicious software programs offline will it help preventing spreading infection and getting hacked / data stealing ? suppose after downloading a pdf from the internet can I get hacked if I block adobe pdf reader and the pdf file both accessing internet . will it possible for the malicious pdf to drop malware / steal data / change firewall setting / encrypt my data like ransomware .
