Switching from Win10 to Linux: AV, defrag, disk cleanup tools, etc

I installed Linux Mint on my desktop in place of Windows 10. I am used to having virus/malware Scanners, defragmenters, Disk Clean up tools etc. I was wondering if people here would be able to recommend similar tools for the Linux OS. With regards to viruses I am taking the better safe than sorry approach as I have seen from my research that virus scanners are not entirely necessary on Linux however, I use my computer to run my online business and would rather not take any chances. I would like to keep my computer running with good performance for as long as i possibly can **Addition** Another query I had is based around Wine With this running as a virtual environment, designed to emulate that of a windows machine. should I be worried about viruses on there? can it contract the same viruses as a windows device?
