Am sure I have lots of malware, spyware fragments on the old machine
Not sure I would want that drive anywhere near any other system, but if it contained data I absolutely must have, I would pull the drive from the infested machine and install it in an enclosure or drive docking station (
NOT in the new system) and
attach it to my new system. Then I would scan the old drive with a whole arsenal of anti-malware programs to include the installed real-time scanner,
Malwarebytes's Anti-Malware (MBAM), and
GMER AntiRootkit.
Then I would copy ONLY the data files I did not want to lose. If the drive contained any program files I still wanted, I would NOT copy them over, but instead, download the latest version from the maker's website. This is to ensure (1) I did not copy over an infected program, (2) to ensure I got the most recent and secure program, and (3) to ensure I got the version for my new OS.
Have HD clones
DO NOT LET THOSE CLONES ANYWHERE NEAR YOUR NEW (OR ANY OTHER) MACHINE! And yes, I am YELLING at you! For sure, if your old machine was infested, these clones will be too - and are a risk to your new system.
I would discard those drives at your nearest electronics recycling center. If you must keep the drives, I would insert the clone HDs in the previously mentioned docking station or enclosure, and totally "wipe" the drives with
Eraser – which uses
DBAN technologies, or use the Drive Wiper feature of
CCleaner (select CCleaner Slim version for no toolbar option).
Finally, if your old system was so infected, that indicates a serious lack of security on that system, and a lack of "safe security practices" on the part of the user (always the weakest link in security). I would suggest you read
Practicing Safe Computing. While a little dated (I need to address Windows 8) it still applies.
