Nod32 not updating
One thing you might want to review is the AV usage.
Per this post I did a while ago: I ran into the same thing after upgrading to the 5.3.47173 agents with Win XP SP3 running Eset NOD32 (v3) and Win7 x64 SP1 running Eset NOD32 (v4).
If that's not the answer, the next thing I'd look at is how many patches you are including in your Detect list.
The current Version of Detection Engine is: 16722 released on January 11, 2018.
To check which version of a specific module is in place in your ESET product, see Access information about product modules in ESET Windows home products.
What you need to do is just clicking the scan button of Autorun Virus Remover.
The common antivirus always can't get rid of the virus completely, the virus comes back after a few seconds of removing it.
