I apologize for the length of this post.
I've owned 2 laptops since late 2016 and on each of the laptops I've experienced the same issues. I used to use Comodo free firewall along with AVAST. (1st laptop) One day I restarted my laptop and found that Comodo was unable to start as was AVAST, so I tried to uninstall and reinstall Comodo Firewall but for some reason it wouldn't fully uninstall and the installer wouldn't allow me to install it without removing the older version, but I was able to restart the AVAST service which allowed AVAST to function somewhat normally. After the aforementioned, I started running several antivirus programs to try to figure out if my computer had been compromised..some of them worked but reported absolutely nothing and some of them wouldn't run at all. Also, the computer was running very sluggish and I would constantly have to use system restore because I wasn't able to boot to the desktop. I eventually decided to clean install Windows 10, but soon after my hard drive failed along with my motherboard
I'm currently on my second laptop, which exhibited the EXACT same issues as the first laptop..restarted the laptop and Comodo had been rendered inoperable and AVAST needed some tweaking to function correctly..security software didn't detect anything, but some wouldn't run at all, sluggish performance, etc. On this laptop I've recently clean installed Windows 8.1 and I'm only using the Windows Firewall, AVAST AV, and MBAM free version, and everything seems to be functioning correctly, but I'm not sure because a day ago I restarted the laptop and was told by MBAM that real time protection had been turned off and that it was unable to load the Anti Rootkit driver and that I needed to restarted the computer, which I did and since then I haven't experienced any other issues. I've run just about every Rootkit detection out there, but none of them find anything. I've ran AV scans using AVAST and Malware Scans using MBAM...nothing is found.
Also, another issue that I'm having is that I'm receiving friend requests on Facebook from strange people that are using my name and are vaguely revealing personal things about my life and it sometimes seems like they know what I'm looking at and doing online (nothing illegal). The question I have here is, am I being hacked? Is there any way to figure out if I'm infected or am I just being paranoid? My two laptops exhibiting the same strange behavior is too big of a coincidence for me to brush off.
Note: The two laptops were never connected and never shared files. The symptoms on the second laptop appeared after my first laptop died.
