Affiliate Marketing Secrets

I was recently testing an old ransomware on my virtual machine running on windows xp (it was a winlock). I have the codes to unlock it, but it won’t let me type in the codes. I am trying to avoid using rescue CDs as they have been proven unsuccessful in the past with russian winlocks. The winlock I have is defined on Dr.Web’s site as trojan.winlock.5310. All the instructions and tutorials are in russian and it would be greatly appreciated if somebody would make a tutorial on youtube for removal.

I have been trying to get rid of this virus. Basically i use firefox. I scanned several times with Malware bytes, hitman pro and a few others. I blocked the websites it takes me to (with the exceptions for cookies in options) and it still takes me too websites like

I have firefox 13 (i think that is the one where it has the stuff in new tabs) and i have windows 7. I think thats all the info you would need. i just want this virus to die in a fire. thanks.

I am worried about my computer getting hacked. Is there any way anyone can hack me without me having to click a link or open a tainted email?
I never click on emails and I only visit safe websites. I have a malware scanner and I run once per day plus anti virus and I have all of my internet settings on high alert. I am also using Firefox.
Can people hack you and access your files without you having to click something?
