Been running comodo now for just on 2 weeks. Started with another free firewall which I used for years. Noticed it was getting bigger and bigger. Had to do a format and reinstall, downloaded my usual firewall and installed, (before the reinstall windows was slow shutting down, problem was traced to the firewall) then the fun began, slow system, slow startup and shutdown and just generally buggy. Uninstalled the firewall and then found comodo and installed it. Bit of a learning curve but getting there.
Must say I am very impressed and will certainly be recommending this software.
Sullo
