These two pieces of software are entirely free. My AnetComputers.com domain name is registered with NameCheap.com. Also, I host multiple websites with NameCheap.com. Namecheap normally responds pretty quickly via chat, whenever I do have issues, which is not that often.
My preferred anti-malware of choice is MalwareBytes. Also, SuperAntiSpyware sometimes removes objects that MalwareBytes won't detect. Finally, I keep ComboFix in my toolkit for those ultra infected computers.
I load either Avast, AntiVirusGuard, or Microsoft Security Essentials anti-virus on used computers I sell or repair. I recommend Avast or AVG to my customers.
CCleaner by Piriform Limited is my preferred computer optimization tool. I use it to clean up files and windows registry. Also, there is a mobile version for administrators and advanced users.
Recuva is one of my preferred applications for damaged or deleted file(s) recovery. PhotoRec and TestDisk are two other preferred Linux based file recovery utilities.
