A week ago I installed Windows 7 and a day later downloaded Office 2013, after establishing a Microsoft account. The following day I received a call alleging to be Microsoft engineers stating they noticed significant infections on my desktop PC. They used showmypc to lead me around my computer and show me alleged virus evidence. I consider myself to be reasonably intelligent and pretty familiar with PCs, but the timing was right for the perps and I'm embarrased to say I fell hook, line and almost sinker. When the dust settled and I stopped just short of commiting my credit card for a $180 "license renewal", I disconnected from the call and tried to remove/uninstall showmypc. Unable to do this, I eventuially attempted a clean install with the Windows 7 disk. It allowed me to remove the existing two partitions and install Windows 7 on a new single partition. When the splash screen appeared, there was a small white icon in the lower left that was obviously not Microsoft generated, containing 4 or 5 "fishy" applet links and a very poor computerized voice describing them. I tried installing drivers from my Msi driver disk, which worked perfectly the first time, but this time got a error box stating the files couldn't be found. Rebooted the Win 7 disk and tried the repair option only to receive a message stating the repairs couldn't be accomplished. Used Trend Micro Titanium Anti-Virus and Windows Security Essentials but they found no virus or spyware. Thinking there might be a bug in the boot sector or MBR, launched bootrec.exe and tried to use FixMbr and FixBoot, but neither one was allowed to function.There are sites that chronicle similar incidences dating back a couple years, but nothing that I could find with a solution to my particular problem. Would appreciate any incite and suggestion that anyone might be able to provide. By the way, on a normal install of Windows 7, is there more than one partition created?
