windows 7 problem

I recently apparently downloaded a program which has infected my pc. It nullified Norton etc and now won't let me disc check or roll back to a previous time - it says that a program was loaded which has stopped me doing so. Any help or ideas urgently requested

Have you got important docs etc backed up? You may have no choice but to reinstall Windows and use a better AV than Norton!

Actually the latest version of Norton is quite good.

Is this thread relevant Computer locked?

Have you removed the program you downloaded?

A few more details are needed, what program? what does it say on the screen?

BTW bad idea to use an e-mail address as your username.

Program causing the trouble is not shown so don't know which one it is. I can still use the computer but can't restore back to clear the problem.

Go into safe mode with networking and download this and run it.

See if that helps.

I should have added if it finds any nasties you will have to activate it then it is free to use for 30 days.

Are you by any chance running two antivirus programs on your pc?

What other antivirus program (besides Norton) and security programs have you got installed?

Note: if you run two antivirus programs in real time they will conflict with each other and cause the symptoms that you have.

and as previously suggested, advise you to change your username. Not a good idea to use your email address.
