[Plugin: AntiVirus] Get an unusual error

I have the exact same problem with those errors on my Add Page screen. This is a site that got hit by malware a while back, so I’m guessing it’s related to that. Deactivating the AntiVirus plugin didn’t make the error go away, so I suspect that has nothing to do with the issue, unfortunately. Setting perms to 777 fixes the issue for me, as well, however, I’m skeptical about doing that as a permanent solution as I suspect there’s some lingering infected file somewhere that wants to inject code or php files into that folder…

I was able to resolve the issue by ripping and reinstalling WordPress over ssh via the method posted about here: http://www.dailyblogtips.com/how-to-upgrade-wordpress-via-ssh/

Hope this helps!

If you’ve got a malicious script on your site, you’re compromised and likely losing business anyway. And if you aren’t yet, you will soon, as your site will likely soon be blacklisted by Google for serving malware.

If you aren’t familiar or comfortable with SSH, basically all that process does is delete the wp-admin, wp-includes and all the files in the root directory of your WordPress install and replace them with fresh copies. Even then, you may still have rogue code in your wp-content directories, in your plugins and themes, but at least that’s somewhat more manageable than digging through every folder in wp-admin and wp-includes.

The reason I prefer SSH over FTP (besides that, if you aren’t using secure FTP, FTP alone isn’t the most secure method of transferring files and can expose your password), is that it’s much faster. Doing an rm -rf ./wp-admin takes a second, wheras deleting the entire wp-admin directory via FTP will take several minutes as it digs into each sub-sub-folder and removes each file individually.

The post I linked to gives a pretty good tutorial, but it is, of course, dependent on your host giving you SSH access.

Thanks Chris!

The error did disappear after I changed the file permissions from 755 to 777 and then back to 755. Also, I found a few corrupt files and cleaned them. I’ll be going through my wp-content folder and replacing plugin files with fresh, updated versions.

Hi,
I have recently run into a similar problem as discussed in this post. I uploaded a plugin – WP Bulletin Board (since removed and deleted the files) and it looks like it has conflicted with my theme, Aggregate (Elegant Themes) or loaded some type of malicious script. My site is still functioning but I can no longer access my editor as well I have warning script above the editor area (it has been pushed down below the warning script) and I also have warning script when I open up an existing page to edit it – the script is under page attributes (it has eliminated my page theme option). I have emailed Elegant Themes for some help / assistance and have yet to get a response from them. I am not a techie and am feeling a bit desperate as to how to fix this. Can anyone help me with this problem? I have updated WP to 3.5.1. The script I am getting is as follows:

Warning: scandir(/home/content/82/5919282/html/travelagentrevolution/wp-content/themes/Aggregate) [function.scandir]: failed to open dir: Permission denied in /home/content/82/5919282/html/travelagentrevolution/wp-includes/class-wp-theme.php on line 980

Thank you, Chris!
I checked out Sucuri and used their free scan of my website and it came out clean – nothing malicious. As I mentioned, I am not technical and do not feel comfortable attempting what you posted above myself. I would rather pay for a service or someone to clean up this mess, however, I want to make sure that Sucuri is the right choice after running the free scan and finding out that my site is clean. If not, what do you recommend?
Thanks, again, for your help!

Also, it’s hard for any kind of automated tool to give you an absolute “yea” or “nay”. Their tool is great, but it does miss some things occasionally.

I had the

after installing wpbb plugin
the way I fixed it was going to the wp-content/themes and setting the permissions on twentyeleven to user read
