I have recently been infected with a fileless malware. I have run a scan with ksc and it reported some memory detection. So,i run a scan with fully updated avast free and emsisoft eek but they didn't find anything. Finally, i have to scan with zemana and only after it detected and removed a fileless malware,ksc was able to give my system a clean sheet. Does kaspersky and zemana the only one to protect against such attacks? I need a free tool to protect my system against such attacks. The detection by zemana was "trojan poweliks: fileless malware". I don't need any whitelisting software and i also sincerely think that even they cannot counter such attacks.
