No specific info about version 19.0. Please visit the main page of Norton Security on Software Informer.
After having held the burden of downloading Norton a couple of days ago, I registered for a trial period, updated the databases even before running the first scan which totalizes a lot of MB/s. I run the antivirus on a full computer round. Awaited for hours (hence, my data storage is considerably big enough for the fast scan to take an hour) & half a day later, the scan completed. Many infections yet uncaught by previously running, multiple security scanners were surprisingly spotted by this one! Nice, very nice indeed,mostly dgen.exe that exploits CPU's capabilities up to the limit on doing nothing at all, thus, slowing dramatically the course of all the rest of the processes. Though I've quarantined & deleted this file in the past by the use of other different means at the time, not to mention having to disable it after each restart, before judging to delete it.
I thought I've got rid of it for good because my PC recovered its usual speed, I was surprised lately by what Norton 1st full PC scan came up with: many infections reminiscences were spotted inside my system images, as well as my old backups.
But the disaster occurred when I decided to deepen the cleansing after the 1st full Norton scan, it wiped some crucial files that weren't infected, though important for the functioning of other application, including my CAD simulator. So I had to restore the entire system back to the preinstallation period & lost by doing so the Norton Scanner.
Oh by the way, I've sent few words of comment to Norton by filling the appropriate check box & have forwarded the results of that long scan. I also rated the program (take a guess)...
The next day I was surprised by coincidentally finding what Norton Security has recently discovered in terms of five-stages built malware while reading the Sofware Informer article by Tanasu.
Using it already 8 years on 3 home PCs.
Norton is a great antivirus, there's no doubt about this. And it provides cloud protection.
