Had a most peculiar telephone call this afternoon from an Indian sounding gentleman who kept mentioning Microsoft and the need to determine if my PC had become infected with a virus . I am a naturally suspicious person and only after a while did I actually disclose I ran Windows XP . Mrs B_R is away at the moment and I was having an admin day anyway so the call was costing this company some expense and at no real cost to me apart from some time . Anyway I was asked to open up the Run window from the start menu and type in a command eventvwr well when I got to this stage I informed the caller I was not happy and hung up .... I just knew there would be other instructions to come . I kept explaining to the guy that my OS had been updated yesterday and when I checked the Microsoft home site I could see nothing advising me of this security threat and this free service . Following recommendations on ARRSE I run Secunia PSI , Malwarebytes in addition to my normal , Norton , antivirus software and none of these yesterday indicated a problem . So have I been the target of an attempt to download some software to control my PC or was it a genuine call ? I was not even prepared to go past the first stage . Any other ARRSE users experienced a similar call recently ?
