computer registry

ahh,, u need to format it, to remove all virus and back to normal for ur OS. After it u need install an antivirus and create a schedule to maintenance ur computer.

much better just to format and install a fresh new windows in yours. Its much more easier to just reinstall than trying to repair it. just save your important files in another hard drive.

If its a virus problem then you might need to scan your entire hard disk formatting only C drive would not solve the issue for few days it would work fine but virus from other drive would again infect your pc when you format you pc i would suggest you to try kaspersky trail version and scan you pc and remove any virus the better option would be to back up all the important files on a DVD and then format you entire pc and not just the C drive this would delete most of the virus from all the drives or you can download kaspersky rescue disk which would scan you pc during boot time its good too just brun it to a cd and run it during boot time formatting the pc would be my last choice

hi, the best way is to format your computer,and if its still occur the slow of your computer,try to run scandisk or checkdisk to check your hard disk if its still in good condtition,it should be zero in bad sector or cluster.
