for the last two weeks I have been getting unwanted popups predictably when I try to open almost any webpage and they are persistent and hard to get rid of. It happens with google chrome or with ie. I have run PC pitstop repetitively but it isn't helping. Now I have a message I can't fet rid of that says my computer is infected with Zeus TRojan Virus error code win32.xepcj. CallSystemAdministrator at 1-855-763-0456. I did call and spoke to an indian woman who said she would help but did not actually provide a name or what her associatin with microsoft, etc, was. I gave her my name and phone number but when she wanted to share my computer I refused and hung up. What is this and how do I fix it?
