Are you Indian by any chance?

scam from an indian call centre, claims to be from some division of windows/microsoft or some other PC "doctor", claims victim's PC is infected with some virus/malware  and attempts to trick caller into allowing remote access to the victims PC, or giving out credit card details

Tried it on us too. Indian dude by the name of "Andrew". Talked about firewalls, windows etc. Told us that Windows had notified them that my PC was running slow.

it is not a scam

THIS IS A SCAM !!!!  BE WARNED !!!  DO NOT DO ANYTHING THEY ASK YOU TO DO !!! IF YOU DO THEY WILL HAVE FULL ACCESS TO EVERYTHING ON YOUR COMPUTER !!! THEY ARE RANDOMLY CALLING EVERYONE !!!

my son answered a call from this number thought it was microsoft then did as they asked!The told him to log onto team viewer.com and then got him to put in a password and bang they are in.I'm so angry. These people are crimminals and need to be stopped!!!!I jave rung team viewer and they are aware of this Indian scam and told me I will have to have my computer wiped. So so so angry!!!
