Sometimes I use the windows registry editor, but obviously I'm not an expert.
In the windows registry editor I've searched the name "savings wizard" and "ajakpekbmnkgnjbpajgkdhimcbeoocam" but I didn't find anything.
I don't know why the folder "C:\Windows\SysWOW64" is opened by itself.
In that folder, "C:\Windows\SysWOW64", I've found 4 strange files of 100mb each one with a chinese name, I've just deleted them.
PD: I've restart and windows looks without changes, the malware continues being in chrome extension.
