Microsoft Security Essentials 188.8.131.52
Microsoft Security Essentials 4.4.301.0 Prerelease
Microsoft Security Essentials 4.4.0304.0
Is the latest version still slowing down windows explorer?(on loder versions, Explorer was less responsive. Folders with files in list mode were slow to have their icons displayed.)
Unfortunately yes. Add explorer.exe to the excluded processes within MSE and that symptom goes away. How that might degrade MSE's ability to protect the system I'm not sure.
Can we still call it "realTime Protection" If windows explorer is not monitored by MSE?!!
Real-time detection, yes. Real-time protection, maybe. I was hoping someone with more knowledge could answer that. I would only add explorer.exe to the excluded processes list if I was running something like Appguard to cover me.
What Happened to MSE
It isn't any secret that recent tests of MS Security Essentials (Defender in 8.x) have shown very poor detection rates, especially on zero day threats.
Microsoft gave a rather weak excuse. They say that of the missed samples, only .03% of their customers have these items on their systems.
When we look at AV test results we extrapolate and say if product Z caught 100% of some selection of malware then it should be able to catch anything. If MSE missed 40% of the test selection, then it has a 40% chance of missing the next zero day attack.
If these samples are so rare, are they being discovered by heuristics that are somehow lacking in in MSE? Is MSE so prevalent that it is now the benchmark for malware testing prior to release, probably.
From years of experience I have found that most malware infested machines had out of date signature files. These systems were purchased with a 90 day version of a major paid AV that simply ran out.
The only way to really know what works isn't easy to ascertain. One must do a census of infected systems and see what they were using that failed. Everything else is just guesswork.
It'd be nice if they fix about slow loading exe icons
When I run MSE or Windows defender they cause my
1000 exe icons in my collecytion loading too slow I've to waiting
each ico images to appear.
When I install other antivirus or deactivate Mse realtime detection.
All exe icons loading fast back to normal appear all instantly.
Most people didn't notice this gap at all.
It has been noticed my friend
It has been complained every now and then.....search MS community and you will see them ...."MSE Slowing Down Windows Explorer"
what surprises me more is their answer.....they act like it s not their product's problem ....it is because of YOUR system (their answer include "disk defragmentation" and other tips to speed up system responsiveness!!!!)
If these issues cause this slowness then why other AVs can load the icons faster? why the program which should be the best in windows compatibility lacks some features comparing to others??!!!
Most probably it lacks technologies like fingerprinting or whitelisting, which the inherently heavier third party AVs use to improve performance. I don't like to rely on performance tests, but in the last two, it shows no improvement in the file copying speed on multiple runs for instance.
I ve asked about it on MS community and this is the moderatore's answer:
Performance of the antimalware engine is constantly under review. Note that MSE is actually the interface, but the real time protection components are shared with Forefront and Defender.
I agree that we've seen a number of reports of the slowness you are describing, but millions of others, myself included, have never experienced this behavior.
a) - steve: the person who represents the millions......
b) millions of others ..... just they don't care or they are not capable to notice this behavior?
How can they fix the problem when they dont even accept it?!!!
The problem is accepted alright, it just hasn't been identified/fixed yet.
One of the reasons I quit using MSE was the Windows Explorer slowdown. Opening a folder with 30 .exe installers took about 120 seconds with MSE but about 5 seconds with any other AV product I tried.
I'm glad that I'm not the only one who experienced all of those Windows Explorer slowdowns of icons loading and so on. Although that was well over a year ago and I haven't touched MSE since. I'm surprised (or maybe not so surprised) that the performance issue hasn't been addressed after all this time. They build the operating system, they build the antivirus (or at least bought it / licenced it) and yet they can't even program the two to coexist.
I am wickedly meticulous about fine-tuning the performance in any of my computers. So clearly that issue with MSE drove me insane and never used it for more than a few hours before I ditched it. Yet, this doesn't happen with any of the other AVs that I have experienced. How can Microsoft not recognize and accept something that is so incredibly obvious?
As a matter of interest.
1. If you open a folder with a lot of exe's/zip etc it is very slow at displaying.
2. If you close the folder and then open it again is it faster the second time assuming it is in the same windows session?
I guess people who like to download a lot of software feel they need better security than MSE so there aren't too many reported cases, but the flaw is there none the less.
I wrote to Gov Maharaj from Microsoft about the slowdown issue when opening a folder full of .exe files. His response was to exclude that particular folder from being scanned.
I remember having this problem several years ago, when I used Windows XP. But in Windows 7, I haven´t ever noticed it.
What an answer!!!
Why to exclude that particular folder only?
Exclude all folders from being scanned. Then you will not have slowdown issues anymore....
Wow, it even beats "teh ultimate panacea" called clean install suggested by another AV's customer service all the time.
That was my experience; on subsequent openings the folder would load normally. (Windows 7 SP1, 64-bit.)
On a related note, opening web pages in Firefox sometimes felt "sluggish" when I had MSE installed. On speed tests, I saw a consistent slowdown of about 50 kb/s when using MSE compared to other AV's with web shields on, so there was apparently some inefficiency not present with other AV's.
That is what I expected.
MSE caches per session as of old.
Excluding a folder is ok'ish as long as it has been scanned first. MSE scans the download (I hope) & the file, if an exe or compressed would be scanned on access.
