OS: XP SP3
Manufactuer: Dell
Model: Inspiron

I believe the source of the problem started from installing Uniblue's Speed Up My PC when I got lazy one day. After installing and running this program it disabled Norton 360. I uninstalled the program and then reenabled Norton. Norton showed in it settings that the Protection was reenabled and tamper-proof was on. When I would startup the computer and the programs loaded, the bottom right tray on the task bar identified Norton as working but once I clicked on Norton it turned to an X and would no longer update or run scans each time on startup. I went through Norton's steps to remove and reinstall Norton but each time installation was unable to complete. I've ran CCleaner and ran scans on Microsoft Security Essentials with no results found. I've tried reinstalling both Kaspersky and Norton (separatly) but without any success. Today I went to uninstall Kaspersky but it failed. I also am now unable to plug a USB into the computer. It asks to reformat it even though it works fine on my other computers.

The virus has not disabled the internet connection, any programs or task manager. Although not to farmilar with XP processes anymore, I've checked through all of them and none look to be dangerous. I've looked through common areas where viruses are usually placed but all attempts to find a source have been unsuccessful. Also the NTFS disk is reading dirty; the results disappear to quickly for me to read them.
