I looked for something like this on bing, and it led me to a community topic saynig newer versions no longer exclude folders in custom scans or fill scans; is this feature well and truly gone, or can it be brought back in newer versions
asking because there are SOME areas I want excluded to make the scan run faster than being bogged down by a collection of big files in one folder
Yes on version 15.1 and higher that option has gone. Everyone is on or will be on 16.0.4 or so soon it definitely has only file exclusion for real time scans only. Sorry that is Mcafee's decision probably as users were moving virused games to that folder .
That was my thought as a volunteer nothing official.
new scan skips files that cannot be virused and does after the first scan take less time as it does not rescan already scanned files unless they are changed so i think.
McAfee Product Manager, here. I'll take a crack at explaining how we've changed the scanning technology & why. But let me first encourage those of you who like the ability to scan a particular file or drive that we are currently working on re-adding that to the product.
McAfee has responded to feedback from users who wanted to be protected, while not paying a heavy Performance price. One way to accomplish this was by shifting to a more Cloud-reliant Next Gen AV engine. Instead of carrying nearly 200MB of DATs (virus signatures) on the PC, we are trimming down DATs to about 1/5 the size and offloaded much of what was previously handled by the PC locally, to the Cloud. Instead of using only signatures & static file attributes, which have to be updated constantly, we are also looking at file behaviors (Dynamic attributes). The end result is detection that is always getting better through Machine Learning (instead of having to try to keep up by logging signatures of known viruses constantly).
Why are scans not looking at as many files?
With previous technology, McAfee would scan every file, every time - unless scans are customized. On a PC loaded with a lot of files, this could lead to a significantly long scan time, and depending upon your PC power, some perceivable lag. With the Next Gen AV, we focus on scripts and anything executable, and those file types which are potentially subject to infection. But file types, like some media which are not a risk, are not included in the On Demand Scans. It doesn't mean they're ignored. Upon access of any file, McAfee is checking for suspicious behaviors - and if seen, the activity is stopped and the file quarantined. And because McAfee is recording any bad behaviors, the product assists in rolling back to previous state.
There is never a perfect approach to Security, but with Next Gen AV we think we have addressed Performance concerns while also improving detection capabilities...kind of the holy grail of AV.
If you want exclusion readded you can add this as an ides in the ideas are. I do feel it would not get support from on high but worth an idea.
