In a sophisticated lab test throughout the year 2015, involving 4 test rounds, 7 products demonstrate their protection, clean-up and, above all, repair capabilities. https://www.av-test.org/en/news/new...es-repair-your-system-after-a-malware-attack/
Clearly you misread the test. There where only two vendors in the test who in every test was able to always install on infected test system and there was only two vendors who where always able to remove all active malware components. Those two vendors are MSE and Avira. All other tested vendors had problems either installing on infected system or cleaning active malware or both. The difference between MSE and Avira was that MSE left behind some harmless non-infected remnants but Avira didn't. So in this test Avira took first place and MSE took second place. And all other vendors in the test where at "the bottom of the heap", to use your words, since they had trouble removing the actual infections.
as long i try to tell: removal is futile - if system was infected there is no way back to a clean machine. you can recover some data with a boot-cd (eg live-linux) but the rest is not trustable: https://technet.microsoft.com/en-us/library/cc700813.aspx "hacked" is the wrong term and if some have cleaned up - what about the security hole from where the attacker/malware came in? it is still present, not closed. and further - which backdoors have also been opened? first three rules of an admin: backup, backup and backup!
I figured you had looked at the wrong column. An empty folder or a string named "here was once something malicious stored, but not anymore" being left behind are not a problem. MSE and Avira removed everything malicious on all test systems. Perfect. The other tested vendors let fully functional infections remain on test system. Surely that is much more worrying then inactive remnants.
I don't understand your post. Considering the most likely scenario is that the AV is always ON, so the first graph is the most applicable for daily use.. Looking at that first table (AV kept ON), there are three columns. The third says HARMLESS REMNANTS, so it seems fair to consider the first tow columns more important (1st=Malware threat prevented cleanup and 2nd=Active components not removed). I read MSE zero threats prevented cleanup and zero components active after cleanup. That is better IMO than AVG, Bitdefender, Este, Gdata and Kapersky. Only Avira did better (0,0,3) while MSE had (0,0, 8 ). So MSE left 8 harmless remnants and Avira 3, all other suites failed to cleanup or left an active component on the system. So to me it seems that MSE ended up second. Why do you state that MSE is at the bottom in all categories?
@Windows_Security Isn't this what you see ? In the last table AV Test lab ranks Avira, then MSE - but last column can throw one off = 97 then 83. 1st - Avira 2nd - MSE
That is "mis-speak" as far as I am concerned. Akin to removing a tick with your fingertips. Those damn tentacles are still embedded in your skin.
I'm surprised at how good MSE is doing, not just Windows 10 Defender. Though leftovers could theoretically cause malware to remember what they collected about you and move on from there, I wouldn't worry about it too much.
