OK, it's only a small part of the OS, and it has to compete with jewels like Adobe Flash and Avast, but still: MSE should receive an honourable mention :t
This is on Win7-64, and it started a few weeks ago:
- in the lower right corner, a greenish popup says that MSE is cleaning your PC
- then it says "no threats detected"
- but you may notice that something does not work any more
- so you find the icon and double-click it
- clicking your way through, you may see something like history (it's "cronologia" on my Italian OS)
- and the dangerous files section is, hooray, empty
- unless you click on the administrator only button
- and
only then you will find the precious tool that doesn't work any more because it's a "serious" threat:
Category: Trojan
Description: This program is dangerous and executes commands received by the attacker.
Recommended Action: Remove this software immediately
Elements:
file: C: \ MASM32 \ JTools \ AlarmClock.exe
Great, so click on the "allow execution" button, another dark screen signalling DANGER, but since you are a) courageous and b) have assembled AlarmClock.exe yourself, you click your way through and allow execution. Job done :t
Job done ::) ??? No, a quick control reveals that the dangerous trojan has not returned to its location. Only solution: Rebuild it...
Here is Jotti's opinion about the file - 1 out of 19, only Avast believes it's dangerous:
Win32:Evo-gen [Susp] is a generic detection used by Avast Antivirus, Avast Internet Security and other antivirus products from
Avast for a file that appears to have trojan-like features or behavior.
Oops, that looks really dangerous, Avast! However, I've found a fantastic workaround:
I added a manifest, and
now it's clean, 0 of 19, hooray!
Fortunately, virus writers are so dumb that they have not yet detected the manifest trick

Redmond, you are pushing Hutch into the arms of Linux... I still resist but...
