Why does Startup Repair happen every time I boot a new install of Windows 7/ Maybe a virus

I have been working on a Toshiba Satellite c655-S5132 for some time.

I reloaded MS Home Premium, ran all updates, Put some pogo.com links on the users favorites for IE,  Installed Avg Free. , but since most updates were installed, it shuts down by itself instead of sleep, then I have to boot and it comes up startup Repair every time. IT does go to Windows 7 home premium system every time but after a lengthy scan of attempting repairs.
I am now booting from the MS 7 cd to do the startup repair but not to confident that it will work.

Im thinking Tdss killer/kaspersky might help.
Does anyone have any suggestions?
I did google it but did not find a definite answer yet.

Thanks all!

Gerbz--It is a little hard to follow just what the present situation is.
What problem caused you to reload MS Home Premium?
Sure, run a scan with your Antivirus program and also MalwareBytes.  It cannot hurt.

But I suggest a Repair Install

Kaspersky did find the Rootkit.boot.Pihar.c so I will see if it does the startup repair again when it shuts down by itself and then I boot.

Thanks jcmarron. I will run Malewarbytes if this does not work.
