The desktop computer at my previous office was attacked by “recycler” malware once. After CD/DVD era, People started using USBs to transfer files to and from the office desktop and their computers or to print their documents via the desktop. The malware hid the files in the office computer, especially the important documents. It took a lot of time to recover, affecting our work productivity.
Since then, we have the computer protected with licensed Kaspersky antivirus software and USB disk security (which was famous at that time). We made sure all the USBs must be scanned with these two security measures. We started using cloud drive links in the emails to minimize the risk of USB viruses and malwares.
