Command Prompt Keeps Popping Up

[KingstonChua]

Hello,

Two days ago my computer was infected by some malicious malware. I ran malwarebyte, norton security, superantispyware, and some other antimalware programs. I was able to remove most of the malware, but I noticed that my command prompt opens and closes quickly once every hour. I suspect that it has something to do with windows command processor because this program only appears on the start up manager of norton security, and does not appear on task manager. Furthermore, when I try to turn off the start up option for windows command processor, it keeps re-enabling itself. What do I do?

Whenever I run the scan on adwcleaner, the program stops in the middle of searching for files (finding 2 threats). A message window pops up and displays the message "Line 10570 (File "C:\Users\KingstonChua\Desktop\AdwCleaner.exe") Error: Variable used without being declared."  Once I press okay to the message window adwcleaner closes. Should I continue to the next step of downloading Sophos Free Virus Removal Tool?

Fixlog.txt

[kevinf80]

Yes just miss out AdwCleaner..

Am I suppose to run the scan again? When I hit scan on the program, it just redirects me to the scan tab where the three threats were found. I just pressed remove selected and exported the txt. I will report to you if any issues persist. Anyway, I would like to sincerely thank you for spending your valuable time to help me through this. I could have never done any of this without you.

[kevinf80]

Yes the log shows the found entries have been removed, let me know if the issue is fixed or still shows...

Excellent, run the following to clean up:

Download "Delfix by Xplode" and save it to your desktop. Or use the following if first link is down: "Delfix link mirror" If your security program alerts to Delfix either, accept the alert or turn your security off. Double Click to start the program. If you are using Vista or higher, please right-click and choose run as administrator Make Sure the following items are checked:   Remove disinfection tools <----- this will remove tools we have used. Purge System Restore <--- this will remove all previous and possibly exploited restore points, a new point relative to system status at present will be created. Reset system settings <--- this will reset any system settings back to default that were changed either by us during cleansing or malware/infection Now click on "Run" and wait patiently until the tool has completed. The tool will create a log when it has completed. We don't need you to post this. Any remnant files/logs from tools we have used can be deleted… Next, Read the following links to fully understand PC Security and Best Practices, you may find them useful.... Answers to Common Security Questions and best Practices Do I need a Registry Cleaner? Take care and surf safe Kevin...
