avast keeps scanning my site
« on: April 22, 2021, 09:31:19 PM »
hello all,

i have a website where AVAST's servers keep scanning for wordpress so much it is causing the site to slow down a bit, and fill up the error/access logs.

i do not have wordpress installed at all since it is bad (vulnerable and CPU intensive)

how can i tell the AVAST servers to scan less?
i dont even have avast installed in any of my devices so i have no idea how avast found my site (i use ESET)

How do you know this ?

Avast doesn't go looking for your site/s, it is a client based scanned that scans web sites (using the Web Shield) when visited by an avast user/s.

i ran a IP lookup on the IP on the website's logs and it said it belonged  to "AVAST Software s.r.o."

Given what you see under Services: Network sharing device or proxy server.  I just wonder if it isn't related to avasts SecureLine VPN product.

So it could be a user (of that SecureLine VPN product) rather than Avast in itself.  However as an Avast User and non user of the SecureLine VPN product I can't say that with certainty.  But if that is the case I can't see how that would differ from a regular visitor.

how would i block/detect if they are using the Avast VPN?
i do not want the site to be flooded with wordpress requests (i dont even have wordpress so it just 404's)

EDIT: that message means it could be a proxy or a shared connection (ie a business/location having tons of computers connected to 1 IP address.)
EDIT 2: also they were making a crap-ton of requests to various directories looking for a XML file in wordpress related folders.

As I said, I'm an avast user so can't offer any advice in that regard.

I have reported this topic in the hope of drawing some avast input.
