Possible Malware/Virus Problem

[partyboy49]

Hi, i've been having regular problems with my computer which I suspect is a virus/spyware/malware problem. Every time i try to open an application it says "Application cannot be executed. The file _______ is infected. Do you want to activate your antivirus software now?" Any help would be greaty appreciated.

Try all of these please.

Try not to restart the computer until one of the tools we use does it for you or tells you to.

Please download and run the below tool named Rkill (courtesy of BleepingComputer.com) which may help allow other programs to run.
 
There are 4 different versions. If one of them won't run then download and try to run the next one.
 
Vista and Windows 7 users need to right click Rkill and choose Run as Administrator

You only need to get one of these to run, not all of them. You may get warnings from your antivirus about this tool, ignore them or shutdown your antivirus.

* Rkill.com
* Rkill.scr
* Rkill.pif
* Rkill.exe

* Double-click on the Rkill desktop icon to run the tool.
* If using Vista or Windows 7 right-click on it and choose Run As Administrator.
* A black DOS box will briefly flash and then disappear. This is normal and indicates the tool ran successfully.
* If not, delete the file, then download and use the one provided in Link 2.
* If it does not work, repeat the process and attempt to use one of the remaining links until the tool runs.
* Do not reboot until instructed.
* If the tool does not run from any of the links provided, please let me know.

Once you've gotten one of them to run then try to immediately run the following.

 
Download and run exeHelper

* Please download exeHelper from Raktor to your desktop.
* Double-click on exeHelper.com to run the fix.
* A black window should pop up, press any key to close once the fix is completed.
* A log file named log.txt will be created in the directory where you ran exeHelper.com
* Attach the log.txt file to your next message.

Note: If the window shows a message that says "Error deleting file", please re-run the program before posting a log - and post the two logs together (they will both be in the one file).

Please run TDSSKiller per the below steps:

* Go to TDSSKiller and Download TDSSKiller.zip to your Desktop
* Extract its contents to your Desktop so that you have TDSSKiller.exe directly on your Desktop and not in any sub-folder of the Desktop.
* Click Start > Run and copy/paste the following Red text into Run box and hit Enter on your keyboard.

"%userprofile%\Desktop\TDSSKiller.exe" -v
 
* Follow the instructions to type in "delete" when it asks you what to do when if finds something.
* When done, a log file should be created on your C: drive called 'TDSSKiller.txt' please add this log to your next reply.

I ran rkill as requested and it worked but when i try to download the link you gave me for the exehelper it says "File not found Firefox can't find the file at http://www.raktor.net/exeHelper/exeHelper.com."

The link works for me. It must be the malware.

Skip down to TDSSKiller.

TDSSKILLER runs for about 2 seconds before i get the "Application cannot be executed. The file tdsskiller.exe is infected. Do you want to activate your antivirus software now?" message and it closes.

Try booting the computer into Safe Mode and then run TDSSKiller.
