Client computer running XPhome, SP2, Brought to me with porn popups and slow performance, locking up etc. Uninstalled all AV-it was not working anyway. He has 5-10 kinds of spam/ad/popup stopping programs that he downloaded over time. Computer is on network connection and can get web pages, but cannot modify the dns server. It goes back to its default every time. Allows me to get some web pages but not others most of the time. See no patterns here except that I cannot get any site that is AV related. Cannot get ESET updates with either NOD32 or SS. Running ver3.0.672 of SS. I thought that maybe the SS would help with the ad problem. Pages popping up with advertising and porn. Can surf most sites OK, but always refuses ESET, Symantec, etc. Always refuses updates. I am at work now and have downloaded LookIntoMyPC and will run it tonight on that machine, but I think it odd that malware is so good that it can provent ESET from any internet connection, but allow other sites. I did run hijackthis last night. We use it at work. It has a couple of active trojans on it. Will need to remove them.
