It’s not an easy task to define right away if you or your company is being attacked by spyware. Nevertheless there are some symptoms which would help you to realize if your problems are caused by malevolent programs:

- getting unwanted e-mails or messages through communications service which contain unsolicited attachments, links or any requests on reporting of confidential data. Such messages can indicate spyware attack.

- unusual operations with your bank accounts or credit cards: purchases you haven’t made, Internet transactions which you’ve issued but haven’t received a corresponding statement etc.
