do you use fierwall ?

No. 1: They can cause too many problems. There seems to be no end to the number of network problems that can be solved by disabling the firewall. 2: I have linux, which for many purposes makes a firewall superfluous 3: I connect to the internet through schools and libraries, where their firewall protects me.

Yes, I use it. I use SPYWARE BEGONE. You should use it because it can clean all the cookies, adware, malware etc.

yes i do use a firewall. i use the windows pre-intalled firewall and zone alarm. zone alarm is a good firewall or you can use bitdefender antivirus it also has firewall... and bitdefender is one of the top 3 antivirus in the market
