upgraded my Wireless U.S.B adaptor which seemed to work ok however when i logged into amazon account it states that due to attempted unauthorised access they blocked entry until i filled in my details including credit card . I then tried my Wife's laptop to access my Amazon account it worked perfectly .

What os are you running?

superantispyware.com

Download this update it and scan your pc

can you post a screenshot of what you are running into on your computer?

The Zeusbot was one of the big players when it came to compromising accounts, not sure if they is what you have or not. Do you have any kind of pc protection on your computer?

Cleaned a computer a few months back with a similar issue with AOL asking for a renewal and credit card (person still had AOL). That was spyware too. Whatever you do don't enter your credit card. Sounds like common sense but, yeah, you'd be surprised with how many people do and regret it.

Also Malware Bytes wouldn't be bad either. MBAM+SAS = real good.

Malwarebytes : Malwarebytes Anti-Malware PRO removes malware including viruses, spyware, worms and trojans, plus it protects your computer (looks like they redid their website since the last time I've been there; that link is for the trial)
