I downloaded a free software program that came as an executable file. Like a dummy, I did not think to scan it before executing the program, and sure enough, it had a trojan: win32:trojano-025, which attached to C:\WINNT\hytr.exe. I have moved it to the chest. What is hytr.exe and can I safely delete it or is it a necessary Windows file?
I also ran the Trend Micro scan and Trend Micro found nothing. Then I ran McAfee and McAfee also identified it as a trojan. McAfee also caught another trojan attached to C:\WINNT\system32\fhccall.exe that both avast and Trend Micro missed. Again, can this file be safely deleted?
