User Comments

as all MailRu ( programs and/or products (services), this is a useless (for me, not for MailRu) thing. It is not a toy, several minutes before I downloaded from a site ( that used to be abs. safe) some utility, that another safe site recommended to use for my problem. the name of the file was the same I needed; though within the *.exe file they packed smth else -- MailRuSputnik.dll. My several antivirus programs DID NOT RATE *.EXe as infected! This means that it is!
