Hello, at beginning March, I received a .docx which I cannot open as only have .doc, the microsoft website suggested I download Free File Opener. Soon after (minutes?) my firewall picked up malware and removed/blocked. Later, a microsoft program told me I had PWS:win32/zbot.gen!AC

Cannot run DDS, as takes ages and then computer crashes. Could be cos my computer already has something strange going on, because I can not account for about 15gig on the hard drive and it is almost full (32gig)

I have run Ccleaner, HJT, downloaded spybot and tried to run it (found 2 hotkeys) but computer crashed just before end of it, so will try again, have run malwarebit anti-malware, ERUNT, and downloaded Microsoft Security Essentials and am going to run that when spybot finishes.



Do I need to do anything else: I would be very grateful if you could advise.

thanks a lot
