Trojan Downloaders


Recommended Posts

I was just doing a backup of my site to my office computer. I am using version 1.6, running the default theme and no custom add-ons.  While downloading the Prestashop folder I was alerted by Kaspersky Antivirus that I had downloaded 3 Trojan Downloaders.JS.Agent.hbs  from the presta\cache\smarty\compile folder. First question, is can I simply delete that file, or should I delete all the files in that folder. Secondly how does this malware get into my site and what steps can I take to prohibit this from happening again? I am not particularly  good with many of the things in Prestashop, so please keep it simple as you can.

 

Thanks

change ftp password

 

check that you folders 755 and files 644 (typical of most hosting)

 

if you delete rogue file, it most likely will be reloaded because other part hacked

 

back office-->advanced parms-->configuation (this will detail changed files from base install).

 

when you get it all cleaned up, check out module PrestaVault.  which will email you when there are file or permission changes with one click restore of file from protected vault.
