i have an issue with avast and would welcome your insights into what might be causing this:
I run a hotel in the UK and we have a website which customers can book off, however people with Avast on their personal machines are unable to access my site hxxp://www.theamblehurst.com. It states there is a trojan on the site!! I have had this looked into from a web designer and he seems to think all the web files on the server are clean. This only happens when people have avast as their antivirus and no other such as norton etc.
Check here how to clean and make a website secure.
The vast majority of malware today is distributed over the web, mostly by means of hacked (otherwise legitimate) sites. The attacker usually injects malicious some scripts into some (or all) pages on the site, waiting for an unsuspecting user to visit the site and possible infect his/her machine.
And this is where avast’s detection capabilities really excel. Its abilities to detect these web-based malicious scripts are second to none, and thanks to the Web Shield and Script Blocking providers, they are used exactly when needed, doing an excellent job stopping the web-based malware right on the entry point.
