A friend has a pc which I believe has had a serious virus issue for some time. Having failed to cure it, and with the most recent symtpoms being no icons, start menus etc on the desktop they have given it to me. The first thing I did was run up-to-date versions of AVG and superantivirus which identified numerous forms of virus, malware et al. Of main concern was two possible rootkits (Rootkit.Agent.gen and Rootkit TDSServ), Virus Rostock G and Vundo MSWorker fake) plus Trojans such as Csrssc, smitfraud (which I believe is responsible for the missing icons), sheur amongst others. I have cleared out all of temp files, cookies etc and tried to remove as much as I can using AVG & Superantivirus but as you would expect I have not been able to remove the serious infections and restore the icons. I have checked the registry settings for explorere.exe and it seems Ok. I can get task manager to run and can see explorer.exe in C:\windows. However I cannot run it as a new task. In addition it is not showing as running in the processes tab. I have also downloaded and run smitrem but the icons have not been restored. Before I go any further and download root detecting utilities and wonder if someone could take a look at a HiJackThis log. This is as at the current state of play. I have one taken before I ran smitrem if it is of any use. Any advice and guiidance as to my next course of action would be appreciated. With thanks.
