I discovered I had trojan "explorer.exe" on my PC. It was loaded invisibly in folder "dllcache" but was an application. Ran Hijackthis and Panda but both got hung up. finally deleted program. Set Zone Alarm Free to block across the board "run a dll as an app". Ran Registry Mechanic and that cleared out some old pieces. Ran HiJackThis again tonight because still having some problems running the real explorer.exe. Opens and looks like My Computer. Though I can put in address and will go to website on the Internet. I typed in default website, verizon.msn.com, but doesn't go there. So something else is still wrong. Any suggestions?

Download Hijack This from this link and boot to safe mode and run it Then copy and paste your log file to the Analyzer Page Then download and run in Safe Mode Ewido Anti-Malware " Please Post back to let us know if we helped "

Also you can download and run Trojan Remover " Please Post back to let us know if we helped "

I downloaded and ran everything you asked me to do and all in safe mode. Found an iexplore.exe trojan, again hidden in a dllcache folder, but is an application. That's now deleted. Found 51 cookies. Gone. Minor changes to the registry have been corrected. It all added up because Internet Explorer is now working great. I now have 2 other problems. First, the "connections tray" whenever I restart or shutdown, doesn't want to close. I always have to select "end now". What is the "connections tray"? What's causing this problem and how can I fix it? I still don't know what brought the 2 IE trojans into my computer. So how do I prevent them from returning? Also, could I have given those trojans to friends, unknowingly? One friend mentioned yesterday that's she's been having problems downloading. What do you think?

Now I found on eother problem - if it is a problem. At the location: c:\windows\system32\dllcache\ First, this dllcache folder is hilighted in blue while everything else is black. Second, it says it's a dllcache, but there are a lot of applications in it. and almost all ofthem have the same date: 8/4/2005 5:00am. What do you make of all of these? There's even a program called regedit.exe.

suzauten, "First, this dllcache folder is hilighted in blue while everything else is black. Second, it says it's a dllcache, but there are a lot of applications in it." That's not a problem. The reason that the folder is hilited in blue is because those files are seldom used and they're compacted. As to the many file extensions that's normal. Tufenuf

But why would a dllcache folder have a copy of regedit.exe in it? The official Windows version of regedit.exe is in c:\windows. So why would an official Windows utility be hiding in a dllcache folder? That doesn't make sense to me.
