Now install your security software.and run a full scan after letting it update it's definitions. 6. Now install any other software you want and configure it all (choose Custom install as you can avoid various bloatware). Now do another full backup & system image. From now on use the system image that Windows Backup made to restore your pc to a fresh state, instead of the manufacturer's restore partition/cd as that's where the bloatware is coming from.
