Been using Spybot 1.60 for a while. Getting a high volume of Spybot pop-up's asking me if I'd like to make changes to the Registry. The vast majority of these pop-up's do not identify whom or what on-board software or other files might be requesting these updates. Most often the request is denied. Just seems practical. It's a Pentium 3, 800 Mhz WINME Compaq Presario 17XL570 machine. Am unable to upgrade to WINXP due to a corrupt HID.EXE file that can only be replaced (according to multiple inquiry's to HP / Compaq) via the supplied hot swappable floppy drive. Sadly, the floppy drive has been misplaced for years and the net value of the PC does not seem to merit spending $20. on eBay for a replacement drive. It's just a back-up PC. Running Avast! Antivirus, AOL 9.0VR, MS Works, RealPlayer, MIE and not much more. Spybot scans (together with Avast!) continue to clear-up any & presumably most if not all potential problems but it's those Registry changing pop-up's that are a concern. A) Should I turn those pop-up's off? Are they necessary? B) If they should be turned-off, how? C) If not, might the pop-up's be signaling some other incompatibility or are they useful? D) Is there no other method to determine exactly what software or other files, malicious or otherwise might be generating or even spoofing - as I continue to deny the Regsistry changes? Thank you!
