That's System Tool
Let's disable the main file manually so you can run some tools. Do you have access to a flash drive?
What I want you to look for is in Application Data (If using XP, otherwise Program Data). There will be a folder, with a file in it of the same "name". This will appear random, but it has a pattern. Look for letters and numbers in this order: lower case, upper case, lower case, upper case, lower case, then 5 random numbers. For example:
Folder -----> pEeHl02508\pEeHl02508.exe <-----file inside
Delete the folder. Now, if you still have no access to the internet, download the following tool to a flash drive from a different computer, then put it on the infected one and run it.This tool is not a toy. If used the wrong way you could trash your computer. Please use only under direction of a Helper. If you decide to do so anyway, please do not blame me or ComboFix.*
Ensure you have disabled all anti virus and anti malware programs so they do not interfere with the running of ComboFix. IF YOU USE AVG IT MUST BE UNINSTALLED OR THIS WILL NOT RUN.
1. Download this file - combofix.exe http://download.bleepingcomputer.com/sUBs/ComboFix.exe
2. Double click combofix.exe & follow the prompts.
3. When finished, it will produce a log for you. Post that log in your next reply please.Note:
Do not mouseclick combofix's window while it's running. That may cause it to stall.
If you have trouble running it the first time, then rename ComboFix.exe to titans.exe and try again.
