CIS makes my laptop slow

My laptop is a new Acer Aspire 4740 – it has 2 Gb ram and a 2.13 GHz Core i3 processor with an L3 Cache.
But sadly, ever since I installed Comodo my laptop has been acting strange and would crash oftentimes.

What are the solutions you could offer me? :slight_smile: (besides removing Comodo completely from my computer – I hear Comodo is a nice product and truly believe it is so except that my machine has an intolerance to it, sadly … :frowning: )

Hope to hear from you peeps soon, thanks!! O0

Make sure that the previous firewall was completely removed. What firewall did you use before? Usually there are removal tools from its maker that can remove left overs from uninstalling.
