I have received a call today Jan 21 from an Indian accent caller saying that he is calling from Microsoft because i sent a crash report from my computer and that there is number of warning from my computers and he offered to help fixing it. he connected to my computer after convincing me that they are from Microsoft. he offered to sell me a package of service on my computer for 1 year and 2 years I refused to buy it and they hanged up. I don't know if they hacked my information , how can I know ? what should I do.
