I have an older computer, Compaq Presario 4770 with a Pentium 200 processor, 32 MB RAM, running Windows 98. I am looking for FREE firewall and antivirus programs that will run on my system. I have tried Avast, AVG, and Zone Alarm, but they all require a faster processor and won't work properly. I cannot afford upgrading or buying new. Does anyone have any suggestions on what I can try?

described a Compaq Presario 4770 (Pentium 200, 32 MB RAM, Windows 98). That class of machine is too constrained for modern, always‑on antivirus or firewall suites; a different approach is needed. ’s suggestion of on‑demand scanning and ’s reminder to check requirements are both sensible starting points.

Practical strategy (short version): rely on network/NAT protection at the edge, use lightweight on‑demand tools and rescue media for periodic cleanups, and avoid resident real‑time scanners on a 32 MB machine. A home NAT router will block unsolicited inbound connections by default and acts as a simple network perimeter (basic protection without taxing the PC). (See a short NAT explanation: )

Recommended, low‑overhead options to look at:

If a host firewall is still required, very small resident firewalls from the 2000s (for example Sygate personal firewall builds) run on Win98 and have low memory footprints — but they are discontinued, so use archived installers carefully and prefer the router approach where possible. (Sygate info: https://filehippo.com/download_sygate_personal_firewall/)

Suggested workflow (apply in order):

  • Isolate the machine from the Internet (unplug or disconnect) and back up important files to removable media.
  • Create bootable rescue media on another PC (for example an official rescue ISO) and run a full offline scan to remove stubborn infections. (ESET SysRescue is an example of rescue media tools.) (ESET SysRescue docs: https://help.eset.com/ees/10.0/en-US/eset_sysrescue.html)
  • After cleaning, run on‑demand scans with a Win98‑compatible scanner and a spyware tool (use legacy builds).
  • Keep file/printer sharing disabled and minimize services; rely on the router/NAT for inbound protection.

Cautions and context: legacy AV/antimalware and old signatures are less effective than current products; many of these utilities are discontinued. Windows 98 is unsupported and inherently risky online long‑term — the safest long‑term fix is migration to newer hardware or using the old machine strictly offline or behind a robust router.

Well, I dunno if it helps much, but if ya want free antivirus SCANS, some websites offer some quality scans...most notably:


http://www.kaspersky.com/scanforvirus.html
http://housecall.trendmicro.com/
http://us.mcafee.com/root/mfs/default.asp?cid=9914

http://www.bitdefender.com/scan/licence.php

For a Spyware scanner, etc,, I'd try Microsoft AntiSpyware (Beta). Its free, and is good for catching things before they start. And, I don't think it takes up too much space...
