Last week I noticed that my scheduled scan by McAfee was taking much longer than it should. I checked and saw that an endless stream of files named "system volume information" were being scanned. It took six hours. I'm an old man with little knowledge of computers, but I managed to find out that these "system volume" files had some use for "system restore". This week I disabled the system restore function before the scheduled scan and scanning was finished in its regular one hour. But I don't know what prompted McAfee to scan system volume info files all of a sudden and I don't know whether I did right or wrong by disabling system restore. My OS is XP SP3.
