They call'd me and said i had problems in my computer though it did'nt but still after their services it really speeded up... i had a problem with my printer as well and they fixed it up too so no matter whether its a scam or not but still i am satisfied by their services....

A quick defrag & empty recycle bin on your computer would do the same thing. Have to mark the above comment as "suspect". Wednesday must be shill day.

I was called by them,
apparently my computer had been sending them error reports for the last couple of days,
They got me to check out my system by talking me though it,
asked me to type eventvwr in the run window.
I see lots of errors at least..
But I have a Computer Engineering friend to ask before I go any further.

If you didn't let them onto your computer you have nothing to worry about.  Your friend  will tell you it's a scam because there is no way they can see what is on your computer.  The error messages are NORMAL - and most computers have many listed - nothing to worry about.  These clowns are probably in India and want access to your information - bank accounts, credit cards. etc.

Its a scam and all they want is your money! They have no way of knowing whats going on with your computer and No legitimate company cold calls like this.  The scam usually entails them taking you to your event viewer which is a internal monitor that logs events on your computer.. Oh sure, you will see the error's logged, but its all a scam to get you to allow them access to your computer. The event viewer is only doing its job and its there for a real tech to look through should you actually have a problem. Then they want remote access! They usually turn your anti virus program off  and give you a big spiel, then inform you they want a small fee to fix it.. several hundred dollars of course! Meanwhile, they have access to all your computer and could be gleaning personal info, downloading stuff to your computer to turn it into a zombie computer to spam folks..

The only persons who should be touching your computer is you, your manufacturer, Real Windows support that you have called and/or maybe a real live tech you see face to face!
