You ABSOLUTELY have an infected computer.
Do steps 2, 7, 8, and 9 here. When doing step 9, the ESET Online Scanner please allow it to FIX or REMOVE whatever is found.
Be sure to REBOOT after using MBA-M and also the ESET Online Scanner.
Be sure to save both the log from MBA-M and ESET. Once you have completed those steps then run a new HJT scan and post back here with all three logs.
Judy

Okay, here are the new logs.

Please give me some good news.

Looks a lot better. Some fixes required with HJT too however.
Run HJT again and place check marks next to the following entries;
R0 - HKCU\Software\Microsoft\Internet Explorer\Main,Start Page = about:blank
O4 - HKLM\..\Run: [AlcxMonitor] ALCXMNTR.EXE
O15 - Trusted Zone: *.antimalwareguard.com
O15 - Trusted Zone: *.gomyhit.com
O15 - Trusted Zone: *.antimalwareguard.com (HKLM)
O15 - Trusted Zone: *.gomyhit.com (HKLM)

Once you have placed the check marks click the Fix Checked button.
Exit HJT.
Reboot the computer and run a new HJT scan and post that new log here.
