I’m working on two machine that have System Guard 2009/vundo infections on them, both systems have been cleaned off with MalwareBytes but they still cannot get updates for any AV software unless you boot into safe mode with networking. I’ve scanned repeatedly with MBAM, I’ve also removed the hard drives and attached them to another machine and scanned with AVG, both are coming up clean. The machines access the Internet fine, I can get to some security sites (symantec.com), but not others (malwarebytes.org). I cannot update MalwareBytes or Vipre in normal mode, neither can I access shares on the local network. I have reset all the zones to default level in Internet Connections, reset TCP/IP using netsh, and reset the local security policy using secedit. I have also performed a repair install on one of the machines…all to no avail. I’m really stumped on this one.
