COMODO Internet Security Comments

I recommend it to everyone.

Positive Comment by FrOssPC
about COMODO Internet Security Jun 2011

I have been using Comodo products for about 4 years now and I love them.
The AV scan is fairly heavy on resources so try to schedule your scans at a time when you're not using the pc.

It's a piece of software that I recommend to everyone.

I would recommend this for high risk users: too much false positives.

Comment by peterstaack
about COMODO Internet Security Jun 2011

I used this for a while, and although it worked well, I switched back to the OS default. I'm a low-risk user, so I found it a bit prohibitive and time consuming with all the false positives. It would often take a bunch of tweaking to get things like my FTP or Box.net apps to work.

I would recommend this for high risk users, though, as it seems to always err on the side of caution.

Okay after some testing, it seems to block my SmartFTP. No idea how to unblock it.

Comodo Antivirus is not so bloated as COMODO Internet Security

Comment by em4020
about COMODO Internet Security and COMODO Antivirus Jun 2011

Comodo Antivirus is a smaller application, not so bloated as COMODO Internet Security :
For the persons, whom COMODO Internet Security appears to bloated, there is an alternative free COMODO application, which offers only virus-protection.

Really nice application, but a bit slow on startup

about COMODO Internet Security Jun 2011

Really nice application, I actually use only Defence+, too bad that it is a bit slow on startup - need to find a better alternative for a weak netbook.

I used this for just over a year, seems very bloated but works... Anyone know of anything a little more "lite?"

It's too bad most programs get so bloated these days...
