Test machine: Windows 7 starter running on an Intel atom (N450, single core) processor. 1 Gb RAM. 160 Gb HDD. A base system restore point was created. Wise 360 was the boot analyzer. Process Hacker provided additional information. Antivirus was installed, tested, uninstalled via Wise Uninstaller, and then system restored for the next program.
I like to have phishing protection and most free antivirus’ do not offer full protection. If an antivirus solution did not have its own built in protection, I ran Mcafee Site Advisor. AVG and Panda each have their own proprietary equivalent protection: So with each of these I ran their software and deleted Site Advisor. (as stated, testing was for personal, not scientific reasons ... hence unusual criteria).
