Some users will put up with certain types of adware in return for free software games for example. But not all adware is equal. At worst, the ads link to sites where malicious downloads await unsuspecting users. Adware can also deliver Spyware and is often easily hacked, making devices that have it installed a soft target for hackers, phishers and scammers.
Spyware secretly records your online activity, harvesting your data and collecting personal information such as usernames, passwords and surfing habits.

Once the attacker is paid, your system and data will usually go back to its original state. A layered approach is important to ensure that all potential entry points are protected. A good business continuity and disaster recovery solution BCDR is a must, too. A BCDR device and plan will not only protect your critical data in the event of a ransomware attack, but also from server failure, fire, or other natural disasters.
