Counterfeit software risks

Counterfeit software is inherently dangerous and poses a number of risks.

  • It exposes you to virus and malware attacks. It lacks sufficient security measures. This can leave the door open for hackers and might have serious implications for you or your business.

  • It can result in corrupted files and data loss. You might lose important personal files and business data, like customer and accounting information.
