I have privacy.securepccleaner on my laptop

Hello and welcome to MGs.

You can always do a clean install if you have the XP CD. I'm not sure why you would do that though rather than cleaning your system.

Doing a clean install wipes your HD. If you want to go that route, you will need to save everything you want saved Before hand. The risk you run is that you have files in there that are infected.

Major Geeks has an excellent cleaning procedure and experts who will make sure you get it all off your system.

If you suspect you have a malware problem (viruses, trojans, spyware, etc.) you will need to perform all steps in the READ & RUN ME FIRST. Malware Removal Guide and post the requested logs (How to attach logs) in a New thread in the Malware Removal Forum.
