How do I upload latest virus definitions to my Kaspersky Boot Disc?

Hi there, I've been told by closed by a couple of members on this forum to create a Kaspersky rescue boot disc, as my laptop is infected with a pretty serious worm virus, so there some documents which I didn't backup on my laptop at the time and I need one of these to limit the chances of infection to those files I believe, before I nackup then reformat and reinstall Windows 7. Basically, I don't think it's a good idea to connect to the internet while my laptop is infected (writing this off a clean PC), so how would I go about updating the virus database of this rescue disc to their latest definitions?

If you've downloaded the latest one from their website, most bootdisks like this will update the definitions before you actually scan with them - once loaded into memory, look for the update option which will download the latest ones, incorporate them into the program and when you then scan it will be with the latest. Obviously you'll have to do this every time you use the bootdisk, as it won't write the new definitions to the cd.

If you boot from a bootdisk, you're not accessing anything through your windows installation, so no problem with being connected to the net to do the above.

Thanks again GunJack And how do I boot from this disc with my Dell M101z laptop? I haven't even turned it on to check for a boot from USB option (hjust bought an external DVD drive) but should it be there?
Basically what I am going to do is: Do the Avast bootscan to begin with (ir tis this Kaspersky good enough?), then upload a good sample of files that I shall be backing up to VirusTotal tp check if they are clean (would this detect a nasty worm like Ramnit?), then upload my files to SkyDrive (I don't have that much to backup after all - maybe less than 500MB rather than 20GB!), then after this, I would basicvally restart the laptop, reformat/reinstall Windows 7. Should this be enough to clean such a harmful virus? I am thinking of going the extra mile and phoning Dell to ask for their restore disc rather than use the image burned into the system on the hidden partion (in case it is infected?).

^^^ close boot with the kaspersky cd and run that first (F2 or Del on power-on to go into BIOS and set your boot priority order. Other than that, probably as good a way as any. Ramnit shouldn't have gone anywhere near your recovery partition, so should be safe to re-install from there. If it turns out not to be so (won't know 'till you've done it, but I doubt it) fall back on the cd image you've downloaded.

Is there a "safe way" to backup the documents I need to back up - what is this safe mode I have heard about, can I do it in that? Or even can I do it during the Kaspersky boot cd? Or am I just going to have to go into Windows the normal way while the virus is there and do it, hoping it doesn't infect them while I am backing them up online?

SkyDrive does seem like the safest option right - seeing as though the worm may transfer to both a USB, external hard drive and DVD ?
