These files are likely signs of a virus infection. Following these steps may help you remove it:
Restart your computer in safe mode:
When you computer restarts, press F8 a few times to display a menu of windows boot options. Select 'Safe Mode With Networking' and press enter.
Assuming this boots up fine lets try and disable the programs from running on statup. While some viruses can be more tricky than others, it is always good to check MSconfig to see if a startup entry is in there.
Click Start > Run and type 'msconfig' and press enter. Look under the startup tab to see if either of those items are displayed, and if they are uncheck them. Also, if you know where the files are on your hard drive, try renaming them to something else so they don't get automatically started. Don't delete the files yet since it is hard to say exactly what they are for yet.
Restart your computer normally. Is everything better now? The next step I would suggest is to run a full virus scan. If you don't have an up to date anti-virus goto http://www.microsoft.com/security_essentials/ and download Microsoft Security Essentials. This is a free anti-virus software from Microsoft that does a very good job. Let it update and preform a full scan to attempt to pick up anything that might be harmful to your computer.
Hope this helps!
