Here at MacD IT Ltd we see a lot of virus and even more commonly now malware attacks on PCs and laptops. When connected to a company network this can cause major issues to the business.
One of the most recent and malicious attacks is Ransomware which infects your PC / laptop and any mapped drives you have on a server are infected and data is encrypted. If the Ransomware fully encrypts the data on the mapped drives you have 2 options, pay the Ransomware or restore the data from a backup. This is a very serious threat which we have dealt with on a number of occasions.
