Windows 10: System security

I been having security issues(I believe) with my system. I have a Dell 3847 all factory except newly purchased RAM of 2x8GB purchased used from Ebay(vendor has over 1000 reviews). I reset my router, changed admin access code, changed password to 2Ghz, 5Ghz, and guest account using separate device. I have only allowed access to the guest account to everyone including myself. I then connected my 3847 to guest account, ran a windows update then completed a full windows defender scan in safe mode which showed zero threats. I then ran a windows defender offline scan, the scan went from 50,000 files scanned to over 100,000 in a matter of 5-10 seconds( I looked away from screen and was talking), then the scan stopped at approx 93% and restarted to windows 10. I was not notified of the results of that scan. I then checked my apps, and somehow all the pre-installed games/apps such as candy crush, Microsoft news, fitbit and all the others were back on my system even though I uninstalled them yesterday when I reinstalled windows 10 via windows usb download tool. I then attempt a second offline scan, windows restarts and goes to the blue screen and shows the offline scan loading bar, 2-5 seconds later the system reboots back to windows without scanning. I submitted about 5 files to Microsoft malware scan only to realize that each scan shows a different windows defender virus definition, here are those results= March 26th 8:10 am=1.291.400.0, March 27th 3:53 pm=1.291.513.0, March 27th 4:15 pm=1.291.532.0, March 27th 6:38 pm=1.291.537.0. Is it normal for the definitions to change based on the file?

Corporate Security Solution

That made me so facepalm. Some people have absolutely no clue. I hope they don't take you for granted with all this you're doing for them.

SonicWall is a good security product, so Mindweaver's suggestion sounds like a good one and should make for a rather bigger baby step. Let's hope they take it.

Best security systems for house?

A house breakout happened in our neighbourhood recently. The house break really freaks me about the security of my house. I am planning to install a good home security and alarm system at the earliest. Thing is i'm not tech savvy and don't know what kind of security systems to choose from. What kind of video surveillance and alarm system is best suited for a house of 2500 sq ft? I read in an online article that Think Protection had good reviews but im not sure about it. Which are the best ones at reasonable rates that I could use? Looking forward to your ideas and suggestions.
