I was talking about the file with the particular MD5 below and not the general Trojan.JS.Agent classification. 6FEC3D1DC6D1802AEADC4F8611A9F326 Anyways here is an article by Mozilla regarding some similar instances of Trojan detection in Cache. https://support.mozilla.org/en-US/kb/Firefox cache file was infected with a virus Can you please ask any malware expert to take another look at the file with the above MD5.

Can it be that the Cache file was pretty old and was recently picked up by Kaspersky as Opentip says it was first seen on 2nd Nov 2025 (SS below)? There were two cache files and one of them I checked on Virustotal and Jotti's malware scan and the other I wasn't able to extract from Quarantine and I deleted it from there. Maybe I had unknowingly visited a sketchy website pretty long back and the file was from then which the Antivirus AI picked up recently after the latest application version update.

Дополнительно не забудьте обновить корневые сертификаты Windows XP по возможности.
