• Your pc may have virus or malware. Download Norton Security Scan , its free.
  
• Perform a DISK CLEANUP as Start -> Programs -> Accessories -> System Tools -> Disk Cleanup
  and also do the defrag of your hard disk partitions.
  
• Also install and scan with Download Ad-Aware
  
• It also happens due to some unsigned drivers, see this help Verify Unsigned Device Drivers in Windows XP

Is it happens with all accounts? or only with your account? create another admin account and see if the problem exist or not. Check for malware with a number of scanners reputable "AutoComplete" should not be present as a task, it is a subsystem DLLs. For IE Explorer Mozilla tasks so fake with almost the same names as system tasks or tasks expected is a trademark of malware tries to hide.

Most probably this is becuase of Internet Explorer.

Try Tools, Internet Options, Content, Autocomplete and click Clear Forms and Clear Passwords. First make sure you really don't need those passwords otherwise upgrading your IE will be the possible next solution.
