Avast! AV detected some potential malware on my wife's laptop running Vista Home Premium. It was trying to pop-up a window that was titled "My Computer Online Scan" and another browser with the title "67.215.238.17/redirectsoft/popup". I got the current Malwarebytes downloaded on my computer, copied it to a flash drive, and installed on her laptop. The update did not work, but I ran the program anyway. Scan found 4 problems and resolved them. I rebooted, rescanned with nothing found, so I was hoping things were OK. I tried to do an update, but it failed. I tried to browse to www.malwarebytes.org, but the page could not be found. I can browse to the site with any other computer on my network, and they are all using the same DNS settings from my router. Pinging from the command line also fails. If I put in the IP address in to the browser manually, I can see parts of the page. I have looked at my HOSTS file, and it looks OK. I have also ran Microsoft's MRT with nothing found. I just installed Vista SP2 via thumb drive also (it would not install from Windows Update). This seems to be acting like a rootkit since it is affecting more than the browser. Any suggestions? I'm tempted to wipe and reinstall from the recovery partition. Brent
