Older OS protections strategies?

I'm running several boxes with either win95 or win98.

I run a firewall and try to restrict everything except what is needed.

I run a good on demand av scanner-avpdos32

These are P150-P800 machines and I've updated some of the patches, like
winsock, but probably not all. I find MS hard to patch since their
patches more often crash a system then help, ime.

On a presario laptop, I'm having problems with touchpad movement
freezing my system requiring cold boot. The other day the cursor went
backwards from where I was moving it. It is possible this may be browser
related to the browser I am using (not one of the main ones), or some
other issue, but it only occurs randomly at certain times. It occurs
irrespective of amount of sys resources being used or whether or not I'm
online, but mostly it occurs online. The lockups seem to occur mostly
when I move the cursor while doing something else. At first I thought it
was resources related, but now it happens even when few programs are
loaded.

Could this be a trojan that my AVP has not picked up? AVP is supposed to
find like 99.5% of trojans. What else can I do to be sure I this box is
not infected?

Also, I have a dialup isp that is notorious for harboring
hackers/spammers. What can I do to ensure someone at the ISP is not
playing with my connection? ID software? Which one?

Thanks for any helpful info.

All you can do is upgrade to a better OS. Try Open BSD.

Where did you pick up this number? Any such number is simply a snapshot
of AVP's performances at a given time in a given context.
AVP's detection rates - or, rather, KAV's (and that's the point)
detection rates - are indeed very high but I'm not sure the DOS version
which you state you are using is still officially supported.

Use another virus scanner to get a second opinion and make sure AVPDOS32
is still supported.

AVPDOS32 was long ago superceded by KAVDOS32 which detects
more malware. Google up a download of KAVDOS32.RAR. Make sure it's
build 135. Be careful to not replace the presumably good AVP.KEY file
you have. And use the extra defs available from sites such as:

http://updates1.kaspersky-labs.com/updates_x

I have no idea why the Swiss site continues to offer AVPDOS32. I know
for a fact, based on tests using a large # of malware samples, that it
fails to detect malware that KAVDOS32 does detect.

I don't think Kaspersky has supported any DOS scanner in quite some
time. For a super GUI version, use v 3.5 from the Swiss site. It's
much faster for on demand scanning than their DOS scanner, and
its realtime monitor is also fast using the default "smart" scan. So
far as I can tell, detection is identical to KAVDOS32, and to other
av products which use the KAV scan engine.

Thanks to you and the other fellow for the good replies. The
AVPDOS32 program accepts the latest virus update files and had
detected trojans that were not found by the latest Sophos, AVG and
TrendMicro Housecall, so I ASSUMED it was working ok. It is very
slow though,especially if I check all files.

I am not disputing what you say, but if it was not working, why
would I get alerts on trojans not detected by either of these
other scanners?
 
Sorry forgot to ask, can I use these later versions, will they
work with the good key I have for AVPdos32?
 
Art,

Sorry to spread this out over three replies, flying by the seat of
my pants tonight. How is this kavdos.rar bld 135 different from
the kavdos133.zip at the .ch website? I could find only only one
third party ftp site for the .rar file you mentioned, and the .ch
official site lists only one version of kavdos which is named,
from memory avpdos133.zip, which is a later version than I have
now.

I didn't say it's not working. I said it didn't detect as much malware
as KAVDOS32. It's not surprising at all that the somewhat crippled
AVPDOS32 detects stuff the others don't.

It's a later version. Higher build numbers are later versions.

I Google up several very quickly.

From a comprehensive German University testing research study.

Well, I asked in this group, but people are uncertain. The current dos
app. at the .ch website is different from the one recommended by Art.
And my somewhat older version still works with the new updates and still
catches trojans other supposedly good AV programs do not.

So, what version to use. My guess is the one currently for dl at the web
site. Why would they put it there if it wasn't supported, or didn't work
well? Anyways I have to find a faster scanner, it is too damn slow.
