Thank you!
Nothing suspicious yet... My harddisc is quite full though, can I just delete the c:\_OTL or is there something else I should do first?

As you've mentioned your C:\ drive is much too full, and we need to free up some space. Windows really needs about 15% minimum free disk space, or your processor will constantly have to "page out" which will slow things down a lot.

Before we removed your "excess" System Restore Points you only had 4.2%, but we removed all but the latest System Restore Point using OTL, so you should now have more free space available, however you probably still won't have 15% free disk space, so you'll need to either remove some of your programs, files and folders, or move them to drives other than your C:\ drive.

However, that's up to you, I can't give you any specific instructions for what you should keep and what you should discard/move.

So, now to remove the programs we've been using to clean your machine ....

To clear out OTL and the files and folders it created.

• Double click OTL.exe to launch the programme.
• Click on the CleanUp! button.
• OTL will download a list from the Internet, if your firewall or other defensive programmes alerts you, allow it access.
• You will be prompted to allow the clean up procedure, click Yes
• When finished exit out of OTL
• Now delete OTL.exe (if still present).

This process will also remove TDSSKiller.

Please read the article below which will give you a few suggestions for how to minimise your chances of getting another infection.

• Computer Security - a short guide to staying safer online

If your computer is running slowly after your clean up, please read.
