how to remove trojan from computer

[barb5]

F-secure found threats on the scan that they couldnt do anything with.It is Generic616817.Downloaded Malwarebytes, it quarantines the ones they foune which is sysWoW64. I found this one in C:\programs files, but it wont let me delete it. I tried to download the f secure scanner but it wont let me download anything. Any help on how to remove these trojans, which is what the malabytes said they are.

Can you not delete the ones which are in quarantine in Malwarebytes?

[barb5]

Yes, and they come right back. I need to delete the whole file , but it says i have to have permission from TrustedInstaller, and i tried,but it wont let me

Start your system in Secure-Mode or even better with an external boot CD or stick with e.g. Ubuntu or anything, then you should be able to delete the file(s).

On macOS use CMD+R to enter the recovery mode and use the inbuild terminal.
