1. In Windows XP click on the Start button, followed by Programs, Accessories, System Tools and finally click on System Restore.
2. The system restore wizard should now start. On the right hand side of the screen two options are shown. Choose "Restore my computer to an earlier time" and click on the next button below.
3. The next screen shows a calendar for the current month on the left hand side. In this calendar you should see certain dates which are shown in bold. These bold dates relate to when a snapshot of system settings would have been made. Click on the most recent date shown in bold. This should now show a restore point in the box on the right hand side. Once you are happy you have selected the most recent snapshot, click on the next button below.
4. Next, a confirmation screen appears showing details of the snapshot that you have chosen. If these details are correct confirm this again by clicking on the next button.
5. Finally the computer will start to close down, this will be slower than normal as it gathers system information before closing.
6. Your computer will restart and will now be restored to the settings as detailed in the snapshot you have chosen.

Loop de vele tips in de
Software Algemeen - FAQ natuurlijk even door, daar is 'ie voor

Daar zijn vele vele virussen genoemd, loop de lijsten even langs.
Je kan verder een bootable CD van een virusscanner pakken (of maken), en via diskette of FTP uptodate maken. En/of backuppen + formatteren + opnieuw installeren natuurlijk.
Verwijderd in "virus maar welke ?" geeft ook een goede tip
