I have a Windows 7 SP1 computer which Symantec Endpoint Protection 12.1.5 gave a pop up warning that a Sonar.SuspBeh!gen1 trojan is trying to access into but no action was taken, which I immediately manually moved to quarentine then later removed.
Unfortunately that was all too late since it did access and modified most of files in main hard disk C and in drive E meaning most of files (.docx, jpeg, pdf, dat, mp4 etc) were modified to size 0Kb.
I have tried several methods but did not work to restore to previous version, now I am down to find a cure.
Is there any program or code to reverse this action?
Help is much appreciate it!
Thanks in advance!
