Well…that depends on what you purchased but the first step after registering it on the internet is the same for all.

Step One -> Do not load or use any other software. Do not surf the internet. Turn off Automatic updates (not necessary for Linux and the Mac). Do go to the manufacturers website and update everything until there are no more updates available. Then go to the operating systems website and do all the updates including custom updates. Turn On Automatic updates except on Windows.

Step Two -> After the millionth reboot or not, reboot once more. This is where we start having to do things different by operating systems.

On the Mac and Linux, while there are few viruses targeted at these operating systems. There are two virus protection systems I trust. F-Secure and AVG. I use AVG on everything I can and F-Secure on the rest.  My reasoning is strictly cost based because performance changes over time but these two perform consistently well and interfere least. Download the trial and pay for it after the trial is up. The internet is a dangerous place. Do a complete backup.

On Windows, Disconnect from the internet. From a clean machine, from Filehippo.com download the most recent version  and load on a flash drive  cCleaner, and Defraggler.

  1. Install cCleaner and run the Registry cleaner three times and then the Cleaner. You only need to backup the first time. If you don’t know exactly what you are doing, leave all the tools alone except System Restore. On Cleaner do not select wipe freespace if you want to use your computer anytime in the future. For this and normal use leave Autocomplete, Saved Passwords, FTP Accounts, Start Menu, and Desktop Shortcuts Blank. The same goes for applications check boxes. Check compact databases. After the last run, on the tools menu select all the restores but the first one and click remove. Reboot and delete the cCleaner backup.
  2. Install Defraggler and Run twice. The first time it will take a long time. The Second time will go much quicker.
  3. Install AVG or F-Secure from the web. You can use Windows firewall and it will be less intrusive for daily use. If you skipped my reasoning above, it is under Mac and Linux.
  4. Be sure to run the Virus Protection full disk Scan.
  5. Do a complete backup.
  6. Turn On Automatic updates .

Step Three-> Use your Computer. If an update appears on your screen, make sure it is not on a web page. Hoaxware tries to look like your computer. Otherwise, make sure you do the updates for all your software. This is the first line of defense against malware.
