A message keeps poping up on my computer that says. your computer is infected. windows has detected spyware infection. then it asks me to download. why do i keep getting this message ,and what must i do.thanks in advance.

First of all, download and run Ccleaner Slim http://majorgeeks.com/downloadget.p... That will clean out all the excess junk on your PC and make the next scans go faster. The best and easiest way to clean it up is to run Malwarebytes (update it and then do a quick scan http://www.filehippo.com/download_m... and remove all it finds.) The next step is to download avast free http://www.filehippo.com/download_a... and allow it to do a bootscan on reboot and move ALL it finds to the chest. After that (I don't know which anti-virus you are using) decide which one you want to keep on your PC. You can only run ONE while on-line, as 2 will have a conflict. Post back if you still have the problem Some HELP in posting on Computing.net plus free progs and instructions Cheers
