  1. The problem with the machine from which the latest logs were taken is that you have an old eamonm.sys driver from v4.5 running. Did you upgrade to EFSW v7 from EFSW v4.5? If so, a restart is needed after installation for new drivers to get loaded. Did you reboot the server? If so, please uninstall EFSW completely, make sure there is no eamonm.sys driver in c:\windows\system32\drivers and install EFSW v7 from scratch.

  2. EFSW v7 doesn't support Windows Server 2003. The latest version with support for this OS is EFSW v6.5.

    If security of your data matters to you, we recommend considering upgrade to a modern, secure and fully supported OS. Installing an antivirus on the server won't make it secure enough and having all known critical vulnerabilities patched is a must. Unfortunately, this can't be accomplished with an OS not supported by the vendor (Microsoft) any more.

    Marcos. Independent of what ESET facilitates in its service, anti-they will no longer work because Google have removed features in the phone. Please acknowledge - Google have stated THEY have removed it - the ESET anti-theft portal isn't going to put it back.

    Do you see support of the Anti-Theft portal listed here? It's not there.

    I use a Google Play version of EMS, have Anti-Theft enabled and I'm able to control it via the AT portal.

    as long as the it shows that the cert. is valid on the download .exe, there is nothing to be concerned about

    I would correct this - as long as there is a timestamp (countersignature), the digital signature remains valid if the certificates used to sign the file already expired.

    Hello, Marcos. Johuan says his .exe has a signature with an expiration date of 06 May of 2019 but itman has expiration date of 12 December 2028. Can you please confirm witch is the right one? P.S. I know both are valid but curious why they  are different. I just downloaded and says 06/05 /19 in the sha256.

    I don't know what executables they checked but it doesn't matter. What matters is the presence of a countersignature which ensures that the certificate was valid at the time of signing the installer:

  6. "JS/ScrInject.b virus is a highly dangerous virus." This must be a joke since it's rather the opposite. It's a very generic detection that may trigger false positives at times.

    By the way: 

    wipersoft_setup_1_1_1100.exe » INNO » {app}\wipersoft.exe - a variant of Win64/WiperSoft.A potentially unwanted application

    The website in question is also blocked as scam and it indeed resembles tech support scams.

     

  7. Most of the packets and communications are MDNS, there was basically no communication through other protocols:

    MDNS is allegedly not natively supported by Windows and you need a 3rd party application like Bonjour to support it, however, it was not among installed or running applications (could be a different one).

    What device is 192.168.0.212? There are many repetitive MDNS queries for "amazon-399dfd5f2.local", what is that?

    206    0.058018    2019-05-18 02:35:52,484647    192.168.0.13    192.168.0.212    MDNS    82    Standard query 0xfa0b A amazon-399dfd5f2.local, "QM" question   

    Maybe related to this?

  8. Please if you are not an advanced user with technical knowledge about how networking works, use default settings. Otherwise setting non-default values may cause issues that you may not be able to resolve yourself without reverting to default settings.

    As to what ARP requests and responses are, you can read about it on Wikipedia (https://en.wikipedia.org/wiki/Address_Resolution_Protocol) or elsewhere on the Internet.

  9. If you have marked your local network as home/office and not as public, sharing via SMB will be allowed within your network but blocked from outside.

    https://www.thewindowsclub.com/smb-port-what-is-port-445-port-139-used-for

    ...it is in our interest to not expose Port 445 to the Internet but like Windows Port 135, Port 445 is deeply embedded in Windows and is hard to close safely. That said, its closure is possible, however, other dependent services such as DHCP (Dynamic Host Configuration Protocol) which is frequently used for automatically obtaining an IP address from the DHCP servers used by many corporations and ISPs, will stop functioning.
