AVG is still considered one of the best AV's out there. Rated higher than many commercial products even.Back in the day, it was a combination of SpyBotS&D, AdAware, and AVG.
For Spyware, still think fairly highly of MalwareBytes. One of the other Tech's in our office has a different anti-spyware he likes. I'll try and remember to ask him tomorrow what it is he uses.
Window key + f ; *.jpg <enter> set it to display details;Something that could go through every directory and find ever JPEG, ever BMP, every MP3, you name it, and tell me where it is, what it is called, etc.
associated DLL's usually are grouped together. Windows DLL's would be under the various folders under "c:\windows\"; Office DLL's are going to be grouped in C:\program files\Microsoft\Office*\, etc.god forbid that Microsoft ever should wisen up and put DLLs all in their own same diectory, let alone optimize directories to work in such a way as similar to the compartmentalization under the hood of a car.
I really wouldn't recommend moving DLL's from their installed location, Performance gains would be minimal at best, and at worst you could completely FUBAR your system.
If you really want to improve performance on an Older system, slap an inexpensive SSD in it, install windows/Important programs to that - keep your conventional HDD for Data storage.
Just an example.
