I'm writing this on a new laptop I purchased yesterday. I will split my issue into two paragraphs to keep this as simple as possible.
Desktop Infection:
My desktop was running Windows 8.1 Pro Student Edition. I was logged into my router settings and noticed that the log reported "DoS Smurf Attack" and listed a bunch of remote TCP/UDP connections. Instantly scanned with Rkill, TDSSKiller, MBAM, and they reported Rootkit.Agent but I couldn't get rid of it. I did a little research, looks like the rootkit set up a SMB Relay attack, and this has been going on for some time. I took everything out of my system, RAM, peripheral cards, etc. I reset the BIOS via CMOS jumpers, used DBAN to nuke my HDD's, and put everything back together. I re-installed Windows 7, did another scan with MBAM, and it still reported that I have the rootkit. Since I was aware of the rootkit, I watched it install drivers as services, open up ports to make remote connections, basically all the bad stuff everyone talks about on here. I also flashed the BIOS to its most current version. It did not help.
Laptop Infection:
I think my laptop had a simple malware infection. I nuked the drive and re-installed Windows 7 and have not observed anything out of the ordinary. I backup everything important to the cloud, so nuking is no problem for me.
Does anyone have some advice for my desktop?
