Questions about firewalls always being ping by others

Q: Master, My Computer always has a lot of strange IP to ping my firewall every 4-5 minutes. What's the solution? In addition, my firewall is rising, every time encountered this problem, I always put those ping my computer IP address into the network blacklist, To make it impossible to spread the virus to my computer. Computer Configuration is XP2, Microsoft 6.0 browser, as well as my home computer Internet access is telecommunications cable, there is a dial-up program. Network connection properties are automatically assigned IP address, is not certain to set IP and child masks? If set, does it affect my dialing program?

Question 1: Besides, I still have a puzzle to ask: My Computer's memory is 512M. It's me. As soon as I open Task Manager, how CPU usage reaches 100%, but it immediately returns to normal level. And the computer is running larger programs such as the joint public, anti-virus software class (rising, Ewido Green version of one of them will appear to panic phenomenon. The phenomenon of the crash is not avoided in safe mode. It is the ice blade that cannot find the illegal process. And the core process SVCHOST.EXE all run under the system32 file.

Question 2: Thank you very much for Laughatyou's enthusiastic help. In order to avoid the problem of computer crash, I do not know how to do it? Also ask you to teach: First, the black list of ping My Computer IP delete, and the computer all from the start of the rising program all shut down to keep it can upgrade, antivirus function, open the firewall of Microsoft. After starting, look at task Manager, found that the computer SVCH0ST.EXE only 5, less than the previous 2, the CPU utilization rate further reduced. Second, there is a doubt, I used to download the first 2-3 years of BitComet movies, TV dramas, which is likely to cause damage to the hard disk, this crash and this can have a relationship?

Answer 1: First of all, the odd IP to ping, is normal. Because there are always people on the web who want to know whether a machine is running for a variety of purposes, ping is the easiest way. If your firewall is open, he won't get any information. At this point, rising firewall do some, a so simple problem, not to alarm to the user. In fact, XP with the firewall in the function is not inferior to rising (in the resource occupancy still have advantages), you can try. It has already put the ping this kind of service to the default screen, you can manually open.

Recommended blacklist do not use, simply from the program design, it will occupy a relatively many system resources.

Answer 2: About the impact of BT on the hard disk, there have been many discussions on the network, but also some articles on how to reduce the damage of BT to the hard disk.

As to whether the computer crash is the cause of the hard drive, this is not very good to determine. Because the cause of the crash is particularly numerous, and the hard disk is the less likely one. If the hard drive has a special sound or something, it's still possible. But these are relatively easy to find, I think you should pay attention to it!
