Comodo Filesystem Filter Driver Is Not Loaded

4/27/2019

I've got a bad browser hijacker. It affects my online banking site, which (fortunately perhaps) displays a generic error code message when I attempt to log in. I suspect it came somehow from Wine, because I use Editplus as my text editor.

The url it redirects to is eaoueopa.com. I also suspect it is controlling my searches because any search involving 'anti-virus' gets redirected to a set of bogus results with pages in non-native standard English, and reputable pages like cnet or Trend Micro don't appear.

It also prevents Comodo and Sophos from running. Commodo reports 'comodo filesystem filter driver is not loaded' and running the terminal commands it suggests sends you back into an endless circle of the same error message. Sophos simply does not run. Literally nothing happens when I load it from the apps menu. A full scan of the file system in clamav doesn't make nay difference. Unearth the oncoming storm zip. I have quarantined all the infected files it reported and it's still there.

I have deleted and created a new profile in Firefox -- that doesn't make any difference.

I tried installing f-prot but that's too difficult for an uneducated user such as myself.

Short of reinstalling Mint, is there anything else I could try?

Go to Tools -> Addons -> Extensions in Firefox and remove any suspicious-looking extensions.
If you can't identify the problem extension, then create a new Firefox profile and start from scratch by running:
You will lose all your bookmarks, browser history, saved passwords, pre-filled forms, extensions, etc in this new profile. That's the point of doing this - a fresh start for your browser.
Set this to be the default profile. Or just choose it from the Profile Manager memory every time (makes it slightly easier to create different profiles to use for different purposes)
Use a Linux-native text-editor. There are many to choose from.
Most importantly, start practising basic internet hygiene by preventing your browser from running javascript except from sites that you need js for (and either trust or partially trust).
Most sites work just fine with javascript disabled, or with a bare-minimum of javascript enabled.
While there are several plugins to do this, IMO the best are:
- uBlock Origin.
These are also available for Google Chrome, and the open-source version Chromium.
I very strongly recommend using a completely different browser (or at least a different Firefox profile) to access your bank's web site. Even better, create a second login account which you use ONLY for internet banking.
Most display managers (e.g. lightdm, gdm, kdm, xdm etc) can be configured to start up a second login screen on the same monitor, allowing you to switch back and forth between, e.g., user1 on tty7 and user2 on tty8 with Ctrl-Alt-F7 and Ctrl-Alt-F8 without having to log out.
Running a local squid proxy is useful as a second line of defense against ads and other malware. Configure it to block known advertising sites, and then either configure all browsers on your machine/network to use it, or use iptables to do transparent proxying (transparent proxying works well for http, but requires a lot of messing around to get working well with https).

Make a copy of your bookmarks and store them as a .json file
Close Firefox
Run in Terminal mode:
Type or copy and paste: rm -r -v ~/.mozilla && rm -r -v ~/.cache/mozilla

Note: you will be asked for your password before this works

Now, import your bookmarks

A file system minifilter driver developed to the Filter Manager model must have a unique identifier called an altitude that defines its position relative to other minifilters present in the file system stack. Minifilter altitudes are allocated by Microsoft based on minifilter requirements and load order group.

To request a minifilter altitude number, see Minifilter Altitude Request.

The current altitude allocations are listed below for each of the following load order groups.
