Hi Gabgab,
Welcome to Adlice.com Forum.
RogueKiller should be able to smoothly handle large files . This is definitely a bug.
However, I was not able to reproduce it on my end. Could you please follow the following process to help us troubleshoot this issue ?
1) Download
RogueKiller (64 bits version) and save it on your desktop.
2) Download
ProcDump and save it on your desktop.
3) Launch the command prompt windows (cmd) with admin rights and copy/paste the following command :
"%USERPROFILE%\Desktop\procdump.exe" -h -m 4096 -ma -accepteula -x %USERPROFILE%\Desktop "%USERPROFILE%\Desktop\RogueKillerX64.exe"
Do not close the command prompt !
4) Please start a new scan. When RogueKiller RAM allocation reach 4gb, a dump file will be created. Please wait until the command prompt closure before terminating RogueKiller.
5) A new file named RogueKillerX64.exe_<datetime>.dmp should has been created on your desktop. Please zip it, upload it on Google Drive/Dropbox and share the link here.
Regards.
