Hi Guys, We have some problem with my PC. I can browse well for several minutes, and then stop responding. When I check, I can not telnet to any ports and when I'm doing "netstat -an", plenty connection that was listed as "SYN SENT" come from my PC to destination port of 445. When I restart my computer, the connection was running well on several minutes, and then stops responding. When I check thoroughly, I'm sensing that every time I'm killing "svchost.exe" that using above 8,000k of memory, the connection starts to run well although only for several minutes. Every time the "svchost.exe" that using above 8,000k of memory appears, my PC stops responding. I have tried several anti virus to detect this but unable to detect this threat. The problem is, when I was formatted my PC, this "scvhost.exe" still appear although not as disturbing as before. But only last for 4 days before I was getting the same effect. Is there some clue for me to solve this ? Please advice.
