If you're frustrated with the time it takes your Windows PC to boot and then it seems to be running slowly you may have too many programs running at start-up - and have come to the right place to identify them. This is the original startup programs (as opposed to processes/tasks) list - one of the most comprehensive and most accurate!
"Name or Startup Item" in the table below refers to how an entry is displayed in MSConfig, Windows Defender or the registry "Run" keys. "Command or Data" refers to the program the entry runs. For further information on this and how to identify and disable startup programs please visit the Startup Content page.
For further information on random startup entries please visit the Startup Info page. For the next few months and foreseeable future I'll be verifying many of the Y, U, N & ? entries via virtual machines. If you can verify/identify those entries with a "?" status (especially hardware specific - such as laptops and motherboards) then please E-mail me (address at bottom of the page) or use the new Message Board.

DISCLAIMER: It is assumed that users are familiar with the operating system they are using and comfortable with making the suggested changes. I will not be held responsible if changes you make cause a system failure.
NOTE: This is NOT a database of tasks/processes taken from Task Manager or the Close Program window (CTRL+ALT+DEL) but a database of startup applications, although you will find some of them listed via this method. Pressing CTRL+ALT+DEL identifies programs that are currently running - not necessarily at startup. For a list of tasks/processes you should try the Process Library from Uniblue, the list at PC Pitstop or one of the many others now available. Therefore, before ending a task/process via CTRL+ALT+DEL just because it has an "X" recommendation, please check whether it's in MSConfig or the registry first. An example would be "svchost.exe" - which doesn't appear in either under normal conditions but does via CTRL+ALT+DEL. If in doubt, don't do anything.
To avoid the database becoming too large, all virus entries are only shown using the registry version which is common to all Windows versions. Otherwise there would be multiple entries for popular filenames that viruses often use - such as "svchost" above for example. Multiple viruses can also use the same startup entries, in this case only those with significant differences (such as file location) are repeated in this database.
NOTE : There are a number of virus and malware entried listed in this database where specific removal instructions haven't been given. If this is the case then you could try SDFix, a program written by AndyManchesta that can remove many different types of Trojans and Worms. See here for a tutorial on how to use the program and here for the latest ReadMe file detailing the fixes included.
IMPORTANT: A number of entries are repeated due to the way that different operating systems display startup items. For example, WinMe lists "POPROXY.EXE" as "Norton eMail Protect" in both MSCONFIG and the registry whereas WinXP lists it as "Poproxy" in MSCONFIG and "Norton eMail Protect" in the registry.
RECOMMENDATIONS:
If you're looking for a startup manager then why not try WinPatrol (by BillP Studios) or Advanced SystemCare Free (by IObit) - both include the option to search this database for a particular entry. Alternatively try Spybot - Search & Destroy (by Safer Networking Ltd) as the startup programs section (select the Advanced mode) includes descriptions from this database. You might also want to try their RunAlyzer and FileAlyzer tools.
There are an ever increasing number of rogue applications appearing these days and many of the removal guides referenced in this database use MalwareBytes Anti-Malware (which now incorporates the now discontinued RogueRemover).
As there are more than 10,000 entries in this database related to viruses, trojans, worms and other malware I recommend you use a quality internet security package. Which ever you choose, keep it updated.
