Okay, I bought this computer (tower) on eBay about 2 years ago it was refurbished and came with 3 burnt copied discs for Windows XP, 7 and one for drivers.
I have been using those discs for my Operating System until only recently (2/3 months ago), when I became more aware of the fact that the discs could possibly tampered with in a harmful way and it had me very worried. I now have Windows 7 installed from a genuine disc.
I'm still not sure if there is anything harmful on the discs, I am quite worried that I may have let a hacker into the computer and home network, who could have access to files and information. So basically I am wanting to find out if this is true or not and would very much appreciate some help and advice.
I guess the step at the moment would be to scan the discs. I have tried scanning before but it was still scanning after 1.5 hours+ for one disc. I thought it would be a quick scan and I am a little anxious about leaving the disc in the computer for a long period. Is there a faster way I can scan the discs, but also in a safe way?
EDIT: I should add: I have scanned my computer with both AVAST and Malwarebytes and they both come up clean. Also tried TDSSKiller and McAfee Rootkit Remover and they are clean too.
