G'day all Yesterday I (very stupidly) opened a file (a .scr file if that matters) that I recieved via Yahoo messenger from a contact, and after it ran it appeared someone else had control of my computer - yahoo closed and then a web page opened asking me to put my password in (which I realised of course was a sham); when I went to do an online scan of my pc it shut down on its own, and when I logged back on I got an error from explorer telling me something had tried to use a restricted memory location. I also found that the system restore tab had dissappeared and when i tried to run system restore i got error messages saying it had been disabled by the group administrator (it is a personal PC and I am the admin). Also I got several errors saying registry editing was disabled by the admin when i tried to open regedit. So I have followed all the steps in the "Viruses/Spyware/Malware, preliminary removal instructions." post, and here is my Hijack This log, can anyone tell if I am now clean? The symptoms seem to have dissappeared, but I have also turned Windows firewall back on, I was running Macafee Firewall at the time the attack happened but it didn't pick up any problems while my PC was being abused Attached AVG and Combofix logs too. Thanks for your help!
