We recommend checking the downloaded files with any free antivirus.
From the developer:
SecuCalc is a security program to be able to lock your calculator and also remember your password even when you exit the program. The password can consist of any keypress up to the maximum of 10.
The only limit for now is you can't use the Enter or the On key for the password since they are used by the program itself (this will be user-configurable in later versions).
You may want to check out more software, such as TZ Spyware-Adware Remover or Hiproxy, which might be similar to SecuCalc.
