Sometimes, it so happens that we encounter an error page while browsing certain sites. We are taken to Google safe browsing diagnostic site with details of the infection of that site or site related to that site.
Here is an example.

Warning! Malware detected, bhutanstudies.org.bt on Google Chrome

Malware warning on Apple Safari
So, what do we have here? It says, The website at www.bhutanstudies.org.bt contains elements from the site internetcountercheck.com, which appears to host malware – software that can hurt your computer or otherwise operate without your consent. Just visiting a site that contains malware can infect your computer. – While browsed on Google Chrome
We get the warning only while browsing on Google Chrome and Apple Safari. For some reason, Mozilla Firefox lets the page through only to alert the Anti Virus Program that a virus has been found. I did not test on Internet Explorer.
How malicious are such sites?
Well, it depends. Here’s a screenshot of Bhutan Studies site with Google safe browsing diagnostics.

Google safe browsing diagnostics for bhutanstudies.org.bt
According to diagnostics, the site appears safe. But not quite. I browsed on Firefox and Avira Antivirus was quick to warn me of the infection and immediately removed both the site along with history and all the cookies associated with bhutan studies web. How bad is the infection? According to google safe browsing data, around 6 pages are infected and as much as 38 trojan(s) are included in malicious software. Now, that’s a lot of trojans.
How did those malwares get there?
- Mostly outdated CMS, themes and plugins.
- Bug on CMS/blog software, themes, plugins
- Malicious codes that come with Premium templates/plugins that you downloaded for free.
- Brute force attack against passwords.
- Others that I don’t know…and which you may know better.
It’s always better to clean such sites as Google and other search engines will block and blacklist infected sites. Always update your site to latest CMS/themes/plugins and never use a premium theme that you downloaded for free as they contain malicious codes.
How do we clean them? For Joomla and wordpress sites, go to SUCURI.NET or click here. I think solutions for other sites are also available there.
Since Bhutan Studies is hosted on druknet, I hope it won’t spread to other sites (if hosted on a shared hosting…)
