If you can not afford to buy a premium theme, using a free WordPress theme is unavoidable! There are many sources to grab a free coat for your baby.

Have you ever thought about this critical problem? Here I want to share you a very wonderful, free and effective solution to avoid the unwanted disaster!

  1. I haven’t heard abut an Anti-Virus for WordPress.. I have used TAC to check my Blogs..Thanks Daniel for sharing it..

    • This is the problem many new bloggers do not know and I hope this tiny piece of information will bring little benefit to them. BTW, I haven’t ever thought 12 in total 17 themes I have installed on another blog include malicious code. In short, they are stealing our back link. Thanks to free stuff and we should give them a few credits but it is unacceptable with this problem. They steal back link and sell on market!

      • I even was shocked seeing this result from TAC.. even one Premium theme also had some backlink codes which TAC found out..

        • LOL. Perhaps you get this from untrusted sources. What will you do now mate?

          • Daniel,
            Many theme designers include a backlink to themselves, as the original designer. I’ve read that this is very common and is similar to a copyright notice. Most designers will permit someone who downloads one of their themes to remove the code for a small fee. Is it possible that this code is often mistakenly identified as malicious by the virus scan?

            Thanks

  2. Just scanned my blog, it’s cleaned.

  3. I just got a message from Google through the webmaster tools that one of my sites has a fishing page. Its a WordPress install and the address they show does not exist in the physical folders on the drive. I am assuming it is something that Hostgator provides for webmasters to add on services. But maybe the site has been hacked. I will have to scan.

    • I JB! I think you should first back up your data and code, then remove all of the code, reinstall and backup data. It is sometime we download a plugin or theme from untrusted sources. Thanks for dropping by!

  4. Hi daniel,
    Thanks for bringing this to everyone’s notice. I’ve never heard of the concept of anti virus for WP blogs until now. I will remember to do this when I use a free WP theme.

  5. I have currently installed Tincredible in which I have found many Malicious Codes but TAC could not find any of theme. I have checked all the files manually and removed the codes. I think TAC is a useless plugin.

  6. Sorry I forgot to mention Tincredible is a theme which I have installed on my blog.

  7. Hi Daniel.

    I wanna asked. I’ve got alert from Antivirus at my mail. This message like this. xxxxxxx.com/wp-content/themes/Dreams-v1/thumb.php?src=/g0../0d1.gif Do you know how to remove it? is it Antivirus automatic will remove it? Thank’s

    • Hi Dimas! You are welcome! I cannot see the image so to be honest, I am not able to give you some advice at the moment. However, I think if you downloaded the free theme from a well-known creator, you have not to worry. Otherwise I suggest you replace the theme with a premium one, specially you are seriously blogging.

      • Hi Daniel. Well, when i clicked the link, suddenly goes to my Home blog. It’s never goes to the target. About my blog theme, i buy it from Themeforest. As far i’m using it, my blog were attacked by SQL Injection and Directory Traversal. I’m contact the SEOegghead, they never respond my message. Do you have some suggestions?

        • I think if you have purchased a premium theme from a well-known WP theme creators, perhaps there will be no problem related to it. Maybe one of your plugin has been infected by malicious codes or so. In this case, I think you should: backup your database, reinstall a fresh WP code, re-download the theme from Themeforest and only install reliable plugins.

          If there is no improvement, I think you should make a switch with the current hosting provider, especially in case you are using shared hosting account. Nice to hear your response.

  8. this is good to all WP theme users this plugin was very useful thank you Daniel .

  9. I recently used this TAC theme its really good working,I have checked all the files manually and removed the codes. I think TAC is a useful plugin.

  10. Thanks, this is really useful info, cause i think it’s not enough when we just scan our sites with Virus Total or URLVoid. Also, i worried about my wp theme have some codes cause downloaded it from untrusted source

  11. Are there any similar plugins or anything else to check the plugins also for malicious code?

  12. A lot of WP theme for free are FULL of malicious code… you better download always official free themes in my opinion. Thanks for this interesting content :)

  13. After I scanned my blog using this plugin, I received color yellow mark which says require_once as the diagram shown above, but it says no virus, so I just updated my theme “twenty eleven” and started to scan again. All of the templates turn green.. Sometimes we need to update our theme and the wordpress itself.. This plugin is very useful for me since I use this..
