There are many places to save executable files are different, but I found two store locations are:
Code:
% Appdata% sysreg.exe
C: \ User \ [username] \ Program Data \ sysreg.exe
C: \ f_install.exe
The EXE files you seach on and remove, then searching for the following folders:
Code:
C: \ Documents and Settings \ User \ Local Settings \ Application Data \ Yandex \ YandexBrowser \ User Data \ Default
C: \ Documents and Settings \ User \ Local Settings \ Application Data \ Yandex \ YandexBrowser \ User Data
C: \ Documents and Settings \ User \ Local Settings \ Application Data \ Yandex \ YandexBrowser
