How To Enhance Your Security With Comodo Cleaning Essentials

Comodo Cleaning Essentials is an on-demand scanner that you can use in conjunction with your existing antivirus program or internet security suite. After downloading the program you can run it without installing it to your hard drive and this can also be done via a USB drive which adds a level of portability to it.

To try it yourself firstly head over to where you can download it for free.


The first thing you will need to do is choose which version you require – 32 bit or 64 bit.

The program is compatible with both versions of Windows XP, Vista and 7 and requires 233 Mhz or better Pentium II or equivalent processor as well as 128 MB of RAM and 210 MB of free hard drive space.

unzip the file

Once you have downloaded Comodo Cleaning Essentials you will need to navigate to where you saved it on your hard drive or USB stick.

Double click on the zipped file to extract it.

run CCE

Now you need to simply click on the CCE application icon to get started.

When you first load CCE you will notice the red line of text at the bottom which says the database is updating. This does take a little while but you should wait for it to complete before continuing.

Comodo Cleaning Essentials offers you 3 options:

  • Full scan (reboots in order to check for rootkits)
  • Custom scan
  • Open KillSwitch

The first two options are fairly explanatory and are much like any other antivirus program you may have used. The full scan is time consuming but thorough, the custom scan is obviously tailored to your needs and will scan as much or as little as you require it to.

The final option, Open KillSwitch, is certainly different though and something you may not have seen before.


The KillSwitch window allows you to view all the running processes on your computer. From here you can terminate, suspend or rename any that are of interest. If you find the number of running processes too large a number to manage then click on View and from there you can filter some out by choosing to only show potentially unsafe entries, such as images in memory that may need further examination, as shown in the image below:

You’ll also notice there are tabs at the top of the KillSwitch screen. These give you access to services, network traffic, BHOs and LSPs (BHOs are Browser Helper Objects and LSPs are Layered Service Providers).

Overall then, Comodo Cleaning Essentials is a useful tool to have in your arsenal. It can be used as a second antivirus program, is portable and gives you a wealth of information that can help you keep your system secure.

Have you used it and what did you think of it?
