microsoft tech calling to try to sell me malware, ccleaner, superaniti spyware after installing new windows 7 os

Dell techs had me buy new Windows 7 OS disc, which I installed yesterday.  Just a few minutes ago, a phone call came in saying they were calling from Microsoft and wanted to run a free scan since I had bought a Microsft product.  They had me download software, malware, ccleaner, superantii spyware.  They ran scans and said I was infected and I should buy these software packs for $79.  Is this a real Microsoft service?  I still have these softwares on my computer, should I delete them?  What other threats may be present if this is not a real Microsoft service?

Its a total scam. Uninstall their software and then run a System Restore back to before you
installed it. Change all your sensitive passwords on all sites - email, bank, credit cards and
others. (Do not do this on the compromised computer and it would be best to do on the
phone or in-person.)

You may even want to revert your system back to factory fresh to be sure their software is
not breaching your security. (Means to re-install Windows Clean - removing everything on
the drive so backup any data before hand.)

No, Microsoft would not call you unsolicited. Nor would they know if any errors existed on your
computer. So those are frauds or scams, to get your money or worse to steal your identity.

No one program can be relied upon to detect and remove all malware. Added that often easy
to detect malware is often accompanied by a much harder to detect and remove payload. So

extreme overkill point and then run the cleanup only when you are very sure the system is clean.
