Hi guys, hope you can help me with this. A family member has gotten his computer infected with the Security Tool trojan. Thankfully he didn't enter his credit card details but the computer is not working properly. I gave him the link to http://www.bleepingcomputer.com/virus-remo...e-security-tool but either he made a mistake or the infection was too clever, and the computer ended up even worse as a result.

He has brought it over to me for fixing (cheers!) When I tried to start it, it got to a screen where you can select options like Safe Mode, Safe Mode with Networking, Last Known Good Configuration, Normal Startup etc, but whichever option was selected, the computer would go through some loading screens and end up back at the options screen, so we couldn't even get into Windows.

I managed to make a series of boot disks on floppies, which got me to the recovery console, and a further floppy with a copy of autochk.exe was needed for it to run chkdsk. After that, I was able to get into Windows. I managed to get Process Explorer onto the machine and disable the Security Tool process as per instructions, but was unable to proceed any further due to Malwarebytes coming up with "Run time error 372. Failed to load control 'vbalgrid' from vbalgrid6.ocx. Your version of vbalgrid6 may be outdated. Make sure you are using the version of the control that was provided with your application."

I noticed a copy of AVG Free version on there, so I scanned the computer with that. It found the Security Tool trojan, and upon rebooting, Security Tool no longer runs, although there is still a link to it on the desktop. The link goes to a now-empty folder in Documents and Settings>All Users>Application Data>78393636.

However, Internet Explorer still won't run, and any application that does run does not generate an item on the Taskbar. Task Manager does now open where it didn't before.

So, it seems I have removed the worst of Security Tool but the computer is still unusable due to IE not opening and probably still infected. I have scanned with DDS and RootRepeal, here are the scan results:

Thanks in advance for any help. In the meantime, I am going to try and install Firefox so it has a working browser, and also update IE from 7 to 8. I will also remove Limewire and tell him not to be so silly in future!
