hi, the smart fortress virus invaded my pc. trying to find a way of getting rid is a problem. i have been trawling the net trying to find a solution and many say start up in safe mode with networking. the problem i have with that is that it just wont do it, it goes straight back to normal mode. if i carry on then it loads up but as soon as i reach the desktop a screen appears threatening to lockdown the pc if i dont pay £100 . it completely covers the desk top screen and i cannot get anywhere. does anybody else know of this problem, how do i cure it? if i load a cd disk up it is also hidden behind the malicous screen so cannot proceed further with that. meanwhile the box of paracetamol i have next to me is taking a real hammering....
It seems you are affected of a Trojan or a CryptoLocker type of virus which interupts ordinary booting sequence(editing of MBR file).
You can try to boot from a Hiren Boot CD which will give you the ability to at lease initiate malware removal process:
Another thing to try is to press CTRL+ALT+DEL when your computer boots to the malware screen.
