Hi Amin, all I know is that renamer virus are normal files thats has a prefix like g on them. They work like normal file while other files or .exe gets broken until reinstalled again. Ex. This are just sample files, in some PC's they've got other letters in place Non-infected files: chrome.exe, mpc.exe, brave.exe, nomacs.exe & cmd.exe Infected files: gchrome.exe, gmpc.exe, gbrave.exe, gnomacs.exe & gcmd.exe Ps. This renamer.virus is connected with Ground.exe files you may find hidden in your startup, roaming and C:/. All files transformed with a changed letter on them while the original file is kept hidden this pretenders run on your rig instead. Can be harmful because some apps will malfunction, while others very annoying. At least Kaspersky in trial mode does way better compared to Windows Defender. So overall if your using Kaspersky to clean a so called "renamer.virus.j" either disinfect those files, or if not possible just delete, remove or uninstall them and reinstall a fresh copy. Then use Kaspersky to block incoming or future renamers.
