The link below is still live, I have just checked.
My advice is DO NOT USE IT. - mzizap
I doubt very much that this is the cause of the problem
I would recommend:
1. A scan with Malwarebytes. Pls note I am not authorised for advice if Malwarebytes finds anything, but you can then of course go to the Malware Self Help and take it from there.
2. I would if Malwarebytes reports no infections, run a standard disk cleanup on XP, ATF cleaner, SuperAntispyware or similar.
3. Backup all possible and then increase the size of the partition on C drive
I strongly advise against even the restricted version of Msizap in the attached link to MajorGeeks, provided with the Microsoft Installer Cleanup Utility.
How to get it
Msizap is included with the install of the Microsoft Installer Cleanup Utility. It's a much smaller download than other things that contain it (developer kits, etc.) Install the Microsoft Installer Cleanup Utility after downloading it from a trusted source (at the time of this writing it has been taken down from www.microsoft.com/downloads).
http://majorgeeks.com/Windows_Installer_CleanUp_Utility_d4459.htmlOpen a command prompt and navigate to the installation directory under c:\Program Files (where msizap is located).
Don't run msizap without knowing what options you want to run it with (for a list of options run msizap /? first).
