so far i have tried booting my pc in safe mode and delete my temp files, i have deleted some suspicious files in my roaming folder in app data, deleted some entries in 'host' file in windows and also tried restoring my data but i had no backup so i couldnt do that.
i am not sure if the malware is removed and also need help decrypt my data.
i am willing to provide any further information about the situation to fix and retrieve my data
