I hope I'm not going out of line by posting this here. Recently I have added another computer to my local network. After connecting to the local network (via ISP) I installed Kaspersky trial to protect the new pc. However, when I wanted to update signature database, it failed. I thought it's something to do kaspersky. Then I wanted use online free scan service of eset/nod32 to my surprise it failed to connect to the specified page. The page exist as I have checked on my other pc. Then I downloaded adaware and installed. Tried to update but same problem cannot connect. So, it looks like something blocking me on the additional pc accessing security websites. Does anybody knows what kind of malware it may be and how to get around? Thank you in advance for your advise.
How are you connecting the local network to the Internet? Are all of your computers on the local network connected to a router, which then connects to your cable/dsl modem and connects to the Internet? Your router may be blocking ports that these applications need open in order to communicate. You might try temporarily connecting the computer directly to the cable/dsl modem and connecting to the Internet and seeing if the problem persists. If it goes away, then the culprit would appear to be your router.
Thanks sparek. The problem is seems to be some form of malware on this computer. I have tried your suggestion just to eliminate the possibility. No luck with the router. For example, i can go nod32 free scan page with my other computer (on same network/router) but the new one take me to either blank page with "aicse.com" on the url bar or failed to connect. I have tried adaware, spybot, kaspersky but none of them can download updates - somehow they are blocked. I google "aicse.com" and it seems that this url associated with "DNSHijacker-85.255" The problem is I can not get rid of it as I can not update the files of spyware/adware removals.
Have you run Adaware on the computer even if it is not updated? Have you tried booting into safe-mode on that computer? You might try checking your hosts file. On Windows XP I believe the file is located in c:\windows\system32\drivers\etc\hosts That file should probably be empty if it is not.
ck101 post a hijack log and I will analyse it for you. Download this tool, and run it on the infected computer an I will go through the log.
