I just purchased a used Windows 7 laptop off eBay. Before doing anything, I' want to scan the laptop for viruses, malware, rootkits, etc.
I am looking for something I can use from a USB drive. If anything malicious is detected I my plan is to return the PC to the seller unchanged, so it's important that I not install any new programs on this laptop. Also, until I do this scan I will not allow the laptop to connect to the internet so it's important that this is a self-contained program with no cloud access. Obviously I would download and update this utility from my existing PC.
Is there a stand-alone Bitdefender virus scanner I can download to satisfy this requirement?
Thanks!
