If a PC running an old version of Windows XP was infected with some virus, tons of spyware and trojans... Then at some point it was totally "cleaned" and secured (i.e. installing latest virus definitions and doing a full system scan & repair + Windows Service Pack 2 & all security patches + different anti-spyware programs to remove all spyware)... Would doing that really fix any and all security-related damages done? Or is a format and fresh OS install required to make sure no holes/ports were left open for attacks?
