No need to try it. If it is Gray Pigeon 2008, it is difficult to kill with anti-virus software, let alone manual... I recommend an anti-virus software combination that I use myself... I can’t say it is the best but now At least I have not tried poisoning. I use Norton Anti-Virus, AVAST ZONE ALARM, Firewall 360 Security Guard. It is worth noting that Norton Anti-Virus 2008 AVAST PRO 4.7 Anti-Virus does not conflict with each other. Norton is domineering while AVAST is more subtle. The combined anti-virus effect is very good, which is mainly reflected in Norton's full anti-virus scan and AVAST's real-time monitoring. Then the two will be very safe when equipped with ZONE ALARM firewall. It is best not to use the same brand of anti-virus and firewall for your machine if possible. If so, you can reinstall Kingsoft Antivirus 2008. If you turn off Kingsoft's real-time monitoring and automatic startup, it will not conflict with Norton. You can use Kingsoft as an anti-virus tool specifically responsible for scanning downloaded files. And 360 has Trojan horses and malicious plug-ins. Very good cleaning effect... The repair function for IE is also very powerful... Except for the above 4 sets of software that cannot make Kingsoft start randomly, others can, such as AVAST Anti-Virus, Norton Anti-Virus, ZONE ALARM Anti-Trojan, Kingsoft Check Download File.360 monitors malicious plug-ins, and your machine will be very safe... This is how I do it. My configuration is CPU AMD 4000 and memory 2G. My machine is also very fast now (Lang﹑￣児Patent, copy BS) Attached download address: Norton: /detail/9/80065.shtml Avast: / Kingsoft: / (Lang﹑￣児organized)
