ADDITIONAL MEASURES TO INSURE A SAFE AND SWIFT REINSTALLATION
One reason I’m spending so much time on this topic is that it’s the most important action you’re likely to take on your computer. Some of what I have to say I only learned after I reformatted my own disk.
Once you have everything in place, it’s easy to do it again. Every time your computer accumulates intruders you can’t get rid of without editing the registry according to instructions from Symantec or your anti-virus company’s support site, you can reformat and reinstall in hours. If you’ve installed too many programs which slows your computer down, perhaps uninstalling them leaves debris in your registry.
Now that I’ve got the procedure down pat, I plan to reinstall every several months.
