Utilizing a Win XP Home SP3 x86 DELL Inspiron 9200 Laptop.
All MS Updataes as of May, 2104 are completed.
May have 'remnants' of a past user using ComboFix.
Had difficulty in using CD/DVD Philips player but after re-installing BIOS from flash problem has gone away - this brings up other questions, though, as to system's integrity.
Would like to have guidance as to best check:
1) System files
2) Remove unnecessary files like remnants of ComboFix or other logs, software, from other tools
3) Check hardware drivers for this model and service tag (or answer questions to what was found from manufacturers site)
4) Remove adware from browsers, if present
5) and any other diagnostic check to make this XP system safe and usable for simple educational needs
This system, once checked, will not be used much for Internet (except training videos from reliable resources and occasional email) but will serve as a standalone system for education: MS Word, DVD, CD, etc.
Thanks ahead of time for any help to configure this system correctly in order to move forward.
