hey i'm having modem trouble on one of my two pc's, and can't stay online long enough to download current definition files for my copies of spybot, ad aware & norton antivirus. i was hoping to scan the problem pc, in case part of my modem trouble is due to spyware or viruses. i just downloaded the current files on my other pc, and was wondering if it's possible to transfer them to the messed-up pc with a thumb drive. if so, are the file names & locations understandable, or is this something i shouldn't try messing with manually? would i just copy the new file to the proper directory & delete the old one? thank you!
