Reboot my laptop, withou losing files

Rebooting simply means restarting.

If you mean reformatting - I’d suggest you do that as a last resort…although it will be difficult without the Disc.

new hard drive and reinstall everything

System Restore

You could try going back to a System Restore Point dating prior to the time of your current problems.

Start > Help and Support > Pick a task = System Restore

Restore my computer to an earlier time

Next

Select a date

Next and follow instructions.

Also, you must not have a very good anti virus program if it let trogans in.

You should have a good anti-virus program that you run at least once a week (daily if other people use your computer or you do a lot of browsing and downloading on the net).

You should also have a good spyware program which you should run at least once a week.

You should also have a good Registry Cleaner program which you should run at least once a week.

I use all of the programs listed below. Besides being good programs, and FREE, you also have the ability to continue working on your computer (online or offline) while the program is running.

AVG is a FREE anti-virus program that is excellent

Spybot - Search & Destroy removes spyware and it’s FREE.

Eusing Free Registry Cleaner is good and relatively fast.
