New fast-spreading threats are on the rise as virus writers seek for financial gain. Modern professional cyber-criminals want to stay unnoticed, and they are using advanced technologies to hide their creations from data security solutions. Their attacks are also more targeted, thus a single company or computer might be the recipient of a specific malware assault. And if the antivirus cannot detect it, nobody does. For example, a hiding spyware can cause severe damage to companies by sending out confidential information and lowering computer performance and productivity.

Modern Internet threats require proactive protection and the monitoring of suspicious software behaviour in the systems combined with traditional signature-based protection.
