I was advised to install Avira as my antivirus programme and Comodo for my firewall. Comodo also has an antivirus programme you can download and I wondered how effective this is and whether it would be better to download both in Comodo?

Since our computer mostly crashes when on a gaming site, I realise that I can put the Comodo firewall in Training Mode so that it learns the sites I want to use in the gaming site and then switch back to Safe Mode the next time and it should be OK. I will try this and, hopefully, our computer won't crash as much.

Compused

Comodo Antivirus is not one of the big time Antiviruses
It's just Comodo trying to get in on the Antivirus market (ie complete Internet Security)
Avira is my personal choice as the best Antivirus, stick with that.

Thank you Kimsland, we will stick with Avira.
