Computer Help Please.....
....my brother in-law purchased a laptop (Acer 5315-2153) from a friend that needed some money. I took it home to check it out. The friend claimed that he had it wiped clean, and it's virtually pretty clean.....but here's my issue.
I can't uninstall the AVG antivirus and install the Avast that I want to use. That's not the REAL issue, but it appears that someone (obviously before my brother in-law has a counterfeit operating system on here. There's a constant message on the computer that says: "You may be a victim of software counterfeiting. This copy of Windows did not pass genuine Windows validation." It currently has Windows XP on it.
Will installing Windows 7 wipe the whole computer clean, or should I format the harddrive prior to installing Windows 7? I guess that's my real issue/question. There's really nothing on the computer that needs to be backed up as my brother in-law never really used it.
Basically, I want to start the computer over from scratch with Windows 7.
