Avast Web Shield Adblock/Adblock Plus false positive
« on: April 13, 2018, 12:04:54 AM »
I'm getting a Threat Detected Sound whenever I visit some websites in Chrome, but no notification or anything from within the Avast UI appears.  According to the logs, i see the following.  It appears that Avast is detecting a trojan from within the adblock javascript when it is activated.  could this be a false positive?  I've done a full scan using Avast, Malware Bytes Antimalware and SuperAntiSpyware and found nothing.  This is in Windows 10 64bit.

the website i visit is: hxxps://www.gundamkitscollection[.]com/

chrome-extension://cfhdojbkjhnklbpkdaibdccddilifddb/include.preload.js [L] JS:Downloader-FHO [Trj] (0) - this looks like the javascript for AdblockPlus extension for Chrome

chrome-extension://gighmmpiobklfepjocnamgkkbiglidom/adblock-bandaids.js [L] JS:Downloader-FHO [Trj] (0) - this looks like the javascript for Adblock extension for Chrome

Hi.

I do use adblock just in Firefox.

Avast blocked that is loaded at the bottom of the page which by the way is false positive.
