I checked in well-known anti-virus programs and found nothing

Virustotal does not scan website for infections, it is a blacklist check

That is not an active real life scan, it is a collective of scan results and may change with every update and detection.
While the site may not be immedeately malicious as such there vulnerable code should be retired for security reasons (take down zip for later reference) e.g. -http://kvktravel.ru
Detected libraries:
jquery-migrate - 1.2.1 : -http://kvktravel.ru/wp-includes/js/jquery/jquery-migrate.min.js?ver=1.2.1
Info: Severity: medium
http://bugs.jquery.com/ticket/11290
http://research.insecurelabs.org/jquery/test/
1 vulnerable library detected
Site flagged here: https://sitecheck.sucuri.net/results/kvktravel.ru  (Is that actual or cleansed?).
Site clean: http://killmalware.com/kvktravel.ru/

Ask for a second opinion from Avast Team Members here: https://www.avast.com/contacts

Mitigate the found vulnerabilities and Avast Team may eventually unblock when they see that as fit.
When site is being unblocked that could be with a coming update.

@Polonus, your question should be answered by my html  scan above

Sites exist a few years, and I do not admit that there was an attack. If there is a virus detected, then it is a mistake

It doesn't matter how long a website exists.
It can be infected any time, any moment and within a second.

The detection is not a mistake as our scans show.
You need to fix all the problems or more and more anti-malware software will gonna block the site.

If you don't know how, hire someone who does know how to run and maintain a website.

The site is not on a blacklist, but there is an active infection right now. That is what Avast is complaining about.
You can find more info about this specific threat for example here: https://blog.sucuri.net/2015/11/jquery-min-php-malware-affects-thousands-of-websites.html
Once you remove the malicious code, Avast will stop flagging your domain. No action is necessary on our side.

avast isn't complaining. It is doing what it is supposed to do. Protecting the users systems. :D

Асхаб
several problems can be avoided by using a dedicated server instead of a shared one.
If there is a malicious website on a shared server and the IP gets blacklisted/blocked, it will mean that your website also will be blocked, even when it is clean.

As said before, cleanup your site to solve at least one of the problems.
