should fulfill its purpose, but there are clearly use friendly programs

How well an antivirus program is actually, you can find at the end of the license period almost always only when one was by then just fully protected and therefore ideally had no problems with viruses, trojans or other malware.
Therefore, I take with antivirus software normally prefer to back programs that I already know and have already proved in the past to be reliable.
On my laptop, so I use long programs Eset, but since I recently alongside also have a netbook, it had surrendered, and a try on this new device to another security program.

With Comodo Have had no previous experience, so I can not give any long-term report, but first can only play the first impressions.
The installation went without greater its difficulties, but not so quickly and in one fell swoop as Eset, but stopped in between several times and took a total of longer than I'm used to this.
This alone is indeed not really a problem, but at Eset appeared to me as a layman simply everything much smoother.
Unpleasant and therefore worth a thick point deduction, I find that the system automatically and without me asking me an extra browser has been playing, I had to delete laboriously again.
It may be that somehow in advance I would have this installation point can prevent, but if this is obviously not so easy for laymen because concretely asked what I want to installations and what not, I was not in any case.

If the program is even partly filled, it runs quietly in the background and does not appear with the computer and slowing it down noticeably.
However, I miss the previous program from my usual very easy for laymen to understand technology, self-explanatory and user-friendly user interface.
Here I have to rely on the fact that all of itself is running properly and I'll automatically guided through the program in an emergency me.

Conclusion: It seems so far to fulfill its purpose, but the installation and operation are still (just for laymen) significantly less pleasant than others, some of them not more expensive programs and automatic, unsolicited installation of another default browser, which one laboriously manually must delete, I find extremely unpleasant.
I will therefore in future, even if the program should my PC by the end of the one-year license period reliable protection, likely to change rather be back on other programs.
