I have suspected for quite some time now, that my anti-virus software was not functioning, even though it appears to be from all the NOD32 support end. As well, I am not getting critical updates from microsoft on automatic update, and when I do a scan for them always, I'm always told there are none. Spysweeper found a "possible hijacker" in the HOST file www.dcsresearch IP address in Host file:220.127.116.11 Correct Address: 18.104.22.168. I ran a Panda antivirus checker, and it says my computer does not have any antiviurs protection. Spybot S&D resident just alerted me that System Startup user entry Change Old data: C:\Program Files\Webroot\Spy Sweeeper\spy New data: ":\Program Files\Webroot\Spy Sweeeper\spy . The only difference I can see is the quotation marks in front of the new data. What's that about? I came across something that said certain Trojans can stop you from receiving "critical updates and patches" and can render antivirus software useless. Is this true, or were my eyes just getting tired from hunting for answers? I would be grateful if any one has any ideas what might be happening.
