the 6 hours was the download times for new versions and updates and scans.
my kasparsky dvd is a 2011 version.. and yes.. it does boot in linux off the dvd, so that it can clan the hdd and other drives to prevent the respawning. once I figured out i was being hit by 2 things.. malware and a trojan, i got with the business.. thus some of my efforts were duplicated. had I known fully what I was up against.. it would have been easier.. but then again.. sheer downlaod times of hundreds of megabytes of data on a basic broadband line is slow..

remember.. i use a small netbook on winxp
when i would do the kasparsky bootup and install.. it was of course last years version.. it wanted to dl new ver ( 111mb ).. then once installed.. it wanted to download new sigs ( 89mb ).. then do a complete scan.. 1+hr.. trojan root kit was gone.. the dang addware was harder to kill.. and I eventually, once i was virus and trojan free, just roleld back a week to a restore point beofre the issue.. that solved 99% of my probs.. lost my favorites list in explorer for some reason.... no biggie.. after the rollback i once again had to get kaspasky going again.. new ver.. new defs..

thus the 6hrs...
You're lucky it didn't infect the system restore points. In fact, I'm surprised it didn't. That is just about the first thing that gets attacked and altered so that you cannot simply run system restore to get rid of it.
Now that it is gone, I would suggest installing something like Auslogics free disk defragmenter, CCleaner and Microsoft Security Essentials.
Run CCleaner to clean up your drive. You should run it logged in as each user of that machine, as it doesn't clean other profiles, just the one you are logged in to at the time.
After it finishes, turn off System Restore. This gets rid of all the past restore points.
Then set the paging file to zero... turn it off. That clears it from the disk.
Now boot into safe mode.
Run Auslogics disk defragmenter and tell it to optimize your disk. This will defrag the drive and optimize any files that are spread out all over the disk. It will pack most of the files to the beginning of the disk. Since the paging file and restore points are gone, it will free up an increadible amount of contiguous disk space. This is one of the best things you can do to speed up your machine.
Once its defragged and optimized, set the paging file size to 3 times your physical memory. Make the min and max settings the same so the file never grows or shrinks. The paging file will get set in one contiguous file and perform much better.
Reboot into normal mode.
Turn system restore back on now and it will make a clean restore point for your system (also in contiguous space).
Finally, I'd make a clone of that disk and put it in a safe place so you can get back to this point in time if needed.
Do this several times a year and you should be O.K. :thumbsup:
As for infected machines at work, I no longer even attempt to solve the mystery. All of our data is stored off of the work machines on network storage systems. We just wipe the machine and restore it from a Ghost image, run windows updates and when the user logs back in for the first time, their data is available to them. As you pointed out, 6 hours of reload, re-update, etc... VS 20 minutes of Ghost restore... its a no brainer(which suits me, as I have no brains! :licking
:laughing:
