Hello, @teveze! Could you please let us know what antivirus software you are using? Thanks!

im using "360 internet security"

No, my antivirus found nothing.
But then again, please understand that your antivirus did NOT report a virus, though it may have forgotten to inform you about the difference.
What your antivirus should have done was "reporting a POTENTIAL virus, found by an HEURISTIC method". This heuristics looked at the code, and thought:
"Yeah. Yeah, I can imagine a Virus doing the kind of things this code is doing. I should alert the user of the threat."
For heuristically found threats, the naming rule is normaly:
HEUR/TypeOfThreat.SomeIDOfHeuristicRuleThatTriggered

Here, TypeOfThreat is "malware", which means "it does not explicitly look like a trojan, nor like a self replicating virus, nor anything else we have a special name for, so we call it just malware".

Try updating your antivirus again, and if this doesn't help, report a supposed false positive to the antivirus company.

Nothing popped up for me and running a Malwarebytes 'Threat Scan' showed no issues. I think that if this were a common problem, a lot more folks would have flocked to the forum to talk about it by now.

There is no malware. The problem is 360 Security, which will quarantine the eso.exe file as including malicious code (the HEUR/malware.QVM20.GEN bit) and make your game unplayable. The solution if this happens involves deleting 360 Security from your system. It's one of those nasty programs that has no easy uninstall option, so you have to do it through the control panel and go back afterwards and delete the lingering files manually. Afterwards, however, the game should function normally.
