My desktop (which I now fondly refer to now as "Chernobyl" was really badly infected w a rootkit, so I'm going to do a clean install from XP to Win 7. Are there any extra measures I should take over the standard reformat/clean install to better ensure total destruction of this scourge? Thanks!

Should you decide to do a clean install from XP to Win 7 due to malware infection, you can back up all your important documents, personal data files, photos to a CD or DVD drive, not a flash drive or external hard drive as they may become compromised in the process. The safest practice is not to backup any executable files (*.exe), screensavers (*.scr), autorun (.ini) or script files (.php, .asp, .htm, .html, .xml ) files because they may be infected by malware. Avoid backing up compressed files (.zip, .cab, .rar) that have executables inside them as some types of malware can penetrate compressed files and infect the .exe files within them. Other types of malware may even disguise itself by hiding a file extension or adding to the existing extension as shown here (click Figure 1 to enlarge) so be sure you look closely at the full file name. If you cannot see the file extension, you may need to reconfigure Windows to show file name extensions. Then make sure you scan the backed up data with your anti-virus prior to to copying it back to your hard drive.

If your CD/DVD drive is unusable, another word of caution if you are considering backing up to an external usb hard drive as your only alternative. External drives are more susceptible to infection and can become compromised in the process of backing up data. I'm not saying you should not try using such devices but I want to make you aware of all your options and associated risks so you can make an informed decision if its worth that risk.Again, do not back up any files with the following file extensions: exe, .scr, .ini, .htm, .html, .php, .asp, .xml, .zip, .rar, .cab as they may be infected.

If you need assistance with performing a clean install or upgrading, you can start a new topic in the Operating Systems Subforums forum.

I'm doing the same thing as smak451, and have a few more questions...

1. Should i disable the internet connection when doing the installation? Just to make sure that while im installing Windows again i'm not infected? (And if windows asks if it should connect to the internet for the latest and greatest stuff, i can safely say 'no' knowing that i can do the updates later when all my guards are up?)

2. I have all the recommended software installed from BC tutorials and stuff. I assume i should install all of these things immediately after windows is installed, and before i turn my internet connection back on? And then do everything else?

3. If i do all these things, I also assume NOTHING should be installed to my computer, or added to my startup routine, or changed in any way, unless i specifically ask for it. Because to be honest, i don't want anything else on my computer !!! if i have to invest 4-5 days down the road to clean it all up. In fact, i'm beginning to think this whole "oooo i have the internet !" thing is way overrated for the amount of maintenance that's involved (just joking - kinda).

4. Is there any legal action being taken against these $@%@ @@#$ @#$@$@$ 2@%^^#^% that install this crap and waste my time? Because I've invested 4-5 days on this, delayed my jobs, and am more than willing to participate in their UTTER DESTRUCTION (legally of course) wherever possible. I'm more than willing to invest twice the time it took me to clean this mess up in helping to destroy their will to survive and have them rationally conclude that suicide by stoning with small pebbles is better than thinking of staying in the malware/virus business (legally of course and by suicide i mean bancrupcy... of course... :thumbsup: see my crazy eyes!! :flowers:
