I NEED HELP, PLEASE AND THANK

I made the mistake of installing Sys Mech Pro 6 plus the Anti-Hacker and the Anti-Virus companions, so I should have known better, enough said; at least it was the 30 days free trial version.

My problem now is that I cannot access all my accounts that are password protected like: the telephone company; the bank; hotmail; etc.

The respective front-end screens still will take my entry info and even my passwords by when I press the magic 'Enter' key they return a beautiful blank white screen, plain-zilch-nada-nyet!!!

The system remains live, no pop-ups; no error messages; I can go back to where I came from but I cannot forward from that point, if I press the 'Enter' key I only get a 'grunt' noise from the 'cpu' telling me that is 'busy' and to leave it alone when only 48 hr before (before Sys Mech Pro6 that is) I was able to access anyone of those accounts and do my biz with no problems.

I don't claim to be an expert but I'm not slouch either and I'm not ashamed to ask for help. I've tried everything that I know, all my settings are the same as before and yet is as if the people at Kespberry have had the last laugh on me.

Please and thank you, anyone?
