I sometimes try to promote Prevx (and now Webroot) products to friends, family, co-workers, classmates, etc, but one thing that I have a hard time explaining is how you guys manage to be just so efficient at scanning. Almost all security software/suites offer a quick scan versus full scan option. However, the quick scan on those products is NOT meant to replace the full scan. With Prevx/Webroot, this isn't the case. The Deep Scan, taking about 2-5 minutes max (so it is a quick scan essentially), IS intended to replace the full scan in most cases as I've been told in the past. I remember hearing from I believe a Prevx support personnel that "the only time you ever need to run a full scan with Prevx is if you have just installed it. If you have had it installed since you loaded your OS you never need to run a full scan." Something of that sort. People tend to have a hard time believing that a 2-5 minute scan is as effective as their Norton/McAfee/AVG/Avira/Microsoft whatever's 30 min to 1 hour (sometimes 2 hour sadly) scans. How can this be explained without getting too technical? Also I am not doubting you guys here, I believe Prevx is the best, I'm just curious fundamentally how it works and why Prevx is able to be just so much better by a long-shot compared to everything else out there. Thanks!
