One of the latest trends for the bad guys is to hack into your website, not to steal your information, but to infect visitors with drive by malware or to display spam messages on your web pages. Most of the time the company is not even aware that they have been compromised which can lead to infected clients, bad publicity, and maybe even legal action.
The good news is that there are free site scanner out there that can do a pretty good job of detecting the most common types of website malware. Click the links below to scan your site. You can ignore any messages that they have to purchase their products (the sites are free for a reason). I recommend running both.
Website Malware Scanners
This scanner does a pretty good job locating malware infected pages. If you manage a WordPress site you can install their Sucuri plug-in which does a local scan and recommends ways to secure your site.
This site goes a little deeper and will find things Sucuri sometimes misses.
Many website infection can be removed either by automated tools or by going to each page on your site, opening the page editor intext mode, and deleting the code inserted (usually at the bottom of each page).
If you do detect an infection and need assistance in not only cleaning up your site but securing it from future attacks please contact Wireguided to help. Thank you.
