My cable modem (ISP) provider has shut me down for 2 days now. They claim that a program has been loaded onto my computer remotely which gives people remote access to it and has been sending spam emails out on my IP address. THey get complaints and have shut my service off. He claims there is no fix for this and I have to do a clean install and reformat the drive. That is almost out of the question...I have too many valuable applications that would get wiped out and don't have reinstall disks. I monitored my CPU usage all day yesterday before they shut me down the second time and when it's idle the CPU is not active.....how can this be happening with no CPU usage? The guy at opt online security dept didnt want to hear anything and said he would continue to shut down my service if I do not do a reformat....uuughhh. I was wondering if installing a firewall would help. I am going to hit comp USA and pick up some firewall software.....what do u recommend? I want something that is effective, simple, and can be bypassed for when I play online games...... thanks!
