The Best Antivirus Programs For 2011 – Coranti Anti-Virus & Anti-Spyware

Right, first things first, this is actually a review of Coranti 2010 Anti-Virus & Anti-Spyware.

Why, then, am I reviewing it as part of a 2011 lineup?

Well, thats because it is a relatively new product from a relatively new vendor and the 2010 version is current and still being updated (I guess some security vendors do actually release their products in the correct year!).


As I mentioned above, Coranti Inc is a new player in the security field.

The company was formed in Japan at the end of 2009 following a successful technology acquisition, though I must confess I only heard of them a couple of months ago.

The antivirus program I’m looking at today was released in June of this year but the technology behind it has been in development for some 4 years.


The primary feature and main selling point of Coranti Anti-Virus & Anti-Spyware is an interesting one to say the least – it uses 4 separate engines – BitDefender, Frisk, Norman and Lavasoft concurrently.

Now I’ve always believed that running more than one antivirus program at a time is a bad idea and I detest security programs that slow my machine to a crawl so I did have some worries when I first fired this program up.

The interface for this program is quite well layed out as you can see in the image above.

At the top of the page there are 9 buttons which lead to specific tasks that you can undertake with the program.

Down the left are the menu options which lead to Coranti’s main functions.

Everything is clearly labelled and easily found and clicking on any of the menu items or tools leads to a whole range of further options which may well appeal to the more seasoned user.

Resource Usage

As I mentioned above, one of my big concerns about running an antivirus program that utilises four engines was what effect that would have upon the performance of my laptop.

The answer was that the effect was nowhere near as bad as I imagined it might be.

If you look at the image above you’ll see that memory usage for the system as a whole was around 600MB and only about 17% processor usage and that screenshot was taken whilst a full system scan was in progress.

I tried opening my browser and searching my hard drive during this time and neither action was sluggish which actually quite surprised me.

Coranti update

As soon as you finish installing the program it initiates an update.

As you can see from the image above, that update is huge – over 300MB in all!

Now that is obviously down to the fact that Coranti is running 4 different engines but, even so, it took a long time to download.

Having said that, it was probably worth it, as you will see below.

Coranti scan

If you look at the image above you will notice that Coranti uses 3 engines for antivirus scanning (the other one looks for spyware).

The downside of this is the fact that it takes some time to complete.

Other antivirus programs that I have used on my laptop take around an hour so to complete a full scan; Coranti still hadn’t finished after almost three and a half hours!

For me this is a quite a big negative, but, it does have it’s plus side too – the program actually detected something that no other program has before now –


– which may be legitimate but is, nonetheless, flagged up as a potentially unwanted program.


There are 3 main types of support available from Coranti –

  • A ticket system
  • A list of frquently asked questions
  • A forum

The forum, however, appears to be incredibly new so I’m not sure at this time just how useful that may be.


Coranti Anti-Virus 2010 can be delivered to you electronically for $49.99 which will give protection to one PC for one year and you also have the option of protecting more PCs and/or for longer periods of time, all of which attract a discounted rate.

Additionally, you can have a backup copy mailed to you for an extra $10.


Coranti Anti-Virus & Anti-Spyware is compatible with Windows XP, Vista and 7.

The minimum system requirements, probably due to the 4 engines, are higher than normal and are as follows –

  • 1GB of RAM
  • 1.3Ghz processor
  • 800MB of available disk space


I was actually pleasantly surprised by this program in the end.

Before I installed it I was expecting a sluggish behemoth but it actually ran quite smoothly in the end.

Having been brought up to believe that running more than one antivirus program at the same time is a big no-no I may now have to look into that premise more thoroughly as I didn’t detect any scanning issues and, in fact, this program detected something that no other anti-virus or anti-spyware program has before.

My conclusion at this time then is that Coranti certainly does offer a good level of protection and that running the 4 engines together is superior to some of the competition that only runs with the one engine.

There is a payoff though, in that the minimum system requirements are a little high – many antivirus programs will run on much older machines.

If you have a modern PC, however, then Coranti Anti-Virus & Anti-Spyware may well be an interesting option worth pursuing.

I for one will be keeping an eye out for this program to see how it fares in the longer term.

    I have to doubt that you actually made use of Coranti. I have asmall business that is being affected by problems with Coranti. I used to have a program called Zondex that I had few problems with for years. APRO have replacedZondex with Coranti. We now have computers that are very slow, un responsive and often have lock ups or crashes that require a reboot. The updates often fail so that the next update is larger. When this happens a number of times ,the updates become very large and fail even more. It has meant that our monthly download contract amount is no longer big enough and we will need to increase it just to satisfy Coranti. Over all I don’t think it is worth the use of the program. It is now costing my small business money due delays and failures.
