Excellent response.I tweaked the INI and trust me it's easy for anyone. You just work your way through the settings like it's a GUI. once you've done it a couple of times you know exactly where to scroll to. And if you backup the tweaked INI you'll only have to do it once. It really is just common sense once you're looking at the INI file. People who are not tech savvy could make a few backups of the original INI so they could practice.
I do recommend for realtime setting heuristics higher than 0 (which is off). Especially if you have over a dual core machine. I recommend 1 overall, which will substantially improve detection of new threats but not increase your false positives any measurable level. Also extreme database is strongly encouraged, it activates many thousands of additional signatures for older threats you stand a chance of running into (but aren't on the outbreak charts). Just setting these two alone will add a significant measure of protection to your PC.
Database options are;
Normal Includes viruses currently spreading as determined by the FortiGuard Global Security Research Team. These viruses are the greatest threat. The Normal database is the default selection.
Extended Includes the normal database in addition to recent viruses that are less prevalent. These viruses may have been spreading within the last year but have since tapered off.
Extreme Includes the extended database in addition to a large collection of ‘zoo’ viruses. These are viruses that have not seen widespread infection rates and are largely dormant today.
