Explorer.exe Closed

Question

Hello, 

Yesterday i got a trojan virus that(i think) deleted my explorer.exe
I can still open Internet via the taskmanager run menu, although i cant open "run" with the microsoft logo+r keys. i cant open any programs except taskmanager register editor and cmd.exe
 
Is there a way to solve this problem?

Hello, Paccus can you able to do a system restore and let me know how that worked but do the system restore a few days before you go the trojan horse, if you can and let me know how it went ok.

By the sounds of it you're kinda stuffed, you can grab an explorer.exe from a version of windows that's identical and copy it back into the computer using a Linux live CD to access the drive (recommend Ubuntu or the one included in Hirens boot CD) but I'd say you're still gonna have issues. Lots of viruses these days are designed to hide in system restore so if system restore is ever accesses the virus/trojan re-activates and you start the whole cycle again. If explorer has been infected then it's likely that other system files have been attacked/damaged as well. Running a virus scanner only tells you what files are infected and either removes the file or malicious code, it doesn't repair the file (so once the damage is done it's done for good).

Best thing you can do is to re-install windows using the disks provided by the manufacturer, although if you can obtain a clean windows disk and have access to all the necessary drivers I'd recommend that for better system performance
