This appears to be an old issue that has resurfaced. Any simple way to remove it?

Hi,

The malware you are dealing with locks mbams detection and removal, but next version of mbam should be able to bypass this and deal with this one. In a meanwhile, to deal with it, * Please visit this webpage for instructions for downloading and running ComboFix:

http://www.bleepingcomputer.com/combofix/how-to-use-combofix

Post the log from ComboFix in your next reply.

Please make sure you disable ALL of your Antivirus/Antispyware/Firewall before running ComboFix..This because Security Software may see some components ComboFix uses (prep.com for example) as suspicious and blocks the tool, or even deletes it. Please visit HERE if you don't know how.

Hi,

Thanks for taking a look at this. I was able to disable all spyware / antivirus but had trouble with AVG. The log is attached as per your requests. Again thanks!

Hi,

I already see now why that key in the registry was not deleted before. You are running Teatimer and Adwatch which both monitor registry changes. Mbam detected the malicious leftover in the registry and either Teatimer or Adwatch probably reversed the deletion again since they may see it as a malicious attempt. This happens all the time with removal tools if you have Teatimer or Adwatch running in the background.

Anyway, Combofix bypasses Teatimer/adwatch, so the key in the registry got deleted now.

* Go to start > run and copy and paste next command in the field:

ComboFix /u

Make sure there's a space between Combofix and /

Then hit enter.

This will uninstall Combofix, delete its related folders and files, reset your clock settings, hide file extensions, hide the system/hidden files and resets System Restore again.

Let me know in your next reply how things are now.

Glad I could help. ;)

Please read my Prevention page with lots of info and tips how to prevent this in the future.

And if you want to improve speed/system performance after malware removal, take a look here.

Extra note: Make sure your programs are up to date - because older versions may contain Security Leaks. To find out what programs need to be updated, please run the Secunia Software Inspector Scan.

Happy Surfing again!
