Spyware, viruses, & security forum: Help to remove - WRL2031.tmp Virus

Hi,

I'm hoping for your assistance with an issue I have on my Toshiba Portege P3500 with MS XP Tablet version OS .. ( NB this machine doesn't have a n Optical Drive so I cannot re-install OS from dics's )

I've managed to get "Combo-Fix" to complete a scan and it has identified as Malware/Virus/Trojan the following;-

WRL1180.tmp - WRL2031.tmp and WRL3678.tmp

I've tried using my Microsoft Security Essentialls plus the following MalwareBytes Anti-Malware, MalwareBytes AntiRoot Kit (Beta), SuperAntivirus, Trojan Remover, Norton Power Eraser, Kaspersky TDSS Killer, Sophos Virus Remover, RKillAntiMalware and MicroSoft Malicious Software Remover all of which have either been blocked by the Virus or allowed to run but have not completed after more than 24HRS , ... or error message says "System Administrator Has Blocked programe from running" and or "This Programme cannot be run in Safe Mode".

I've also tried running RootKitRevealer, VBA32AntiRootKit Scanner, MalwareBytes FileAssassin and HiJackThis with a view to finding and deleting said "Infected File" .... but, this Virus/Trojan will not let me "Un-Hide" the hidden files and folders in the Explorer File View menu.

I've also tried to install the XP Recovery Console with a view to return to factory settings but this virus/trojan hijacks the keyboard and won't stop inserting the letter "s" at the command line promptand and all address box's.

This Virus/Trojan aslo hijacks any/all attempts to use the MicroSoft Windows Update by slowing sytem to almost a stand still with Desk Top and Start Menu Icons intermittantly flashing.

Any assistance and advice on how to remove this Trojan/Virus and/or re-install the OS on a machine without an Optical Disc Drive or a BIOS that cannot be set to boot from USB Flash drive would be most appreciated.

Many thanx in advance,
Regards,
Chris.
