OT: OS changes...possible virus infection?

    Off-topic, but any other NG with "virus" in its name seems empty.

    On a home-built dual processor rig, I run the latest Grisoft AVG 7
    free anti-virus package, and update at least twice a week. I have
    partitions (logical and physical) for the OS, all other programs, and
    all data. I run Windows 2000 (latest service pack) on this dual
    processor workstation connected via a router to a DSL modem.

    I also use POPfile and Ewido security/anti-spam software.

    I notice that when I scan either selectively (C: drive for the WINNT
    and F: drive for all e-mail and downloads) or do "full scans" (two
    hours over 13 partitions), I rarely find a virus of any description. I
    have, however, found that AVG notes the following files as "changed"
    (AVG reports zero infections).


    Equivalent scans on my laptop running AVG 7 (latest update) under
    WinXP (latest SPs) does NOT show "changed" in these system files.

    I noticed in the last month also that my domain and a couple of my
    e-mail addresses had been "harvested" and that I was being "spoofed".
    While I have blocked false e-mails, I am wondering if I have a problem
    and what to do about it.

    I don't know if this is of any use, but can you try Symantec
    Security Check? It's a free online service for which they try to
    sell you products. It's useful and not pushy, in my opinion.

    Good luck.

    For what it's worth.

    Other related groups:

    I was browsing two days ago when ZoneAlarm advised me that a program
    was trying to dial out. The program name was obscure. Then another
    obscure program tried to dial out. I checked the hard disk at the
    ZoneAlarm identified location and did not see that program (all
    Windows files exposed). Very suspicious. So I went to Symantec's web
    site and ran the virus check. It found at least one infected file. I
    rebooted to my PartitionMagic CD, deleted the current Windows
    partition, and copied back a replacement. And that was the end of
    that problem.

    Sounds like you've downloaded Spyware into your system, and that's causing
    the problems.

    Try running another anti virus programme. I've used AVG for year and never
    thought it was a problem but I kept getting bounced emails from an email
    address that was never given out to anyone (just set up locally for
    testing). I downloaded and run Kapersky and it picked up two trojans and a
    virus that AVG missed.

    Well, I've loaded CW Shredder, SpySubtract, Spybot S+D, and Ad-Aware
    so far...

    I've found quite a few suspicious files, dialers, cookie redirects,
    and possibly e-mail harvesters. Nothing that would change Windows 2000
    OS files.

    It's becoming an education. Thanks for the advice. Free is good, and
    they can pitch me while I wait.

    Those file were immunized and they are ALWAYS changing. after every
    software upgrade/update hardware change, stuff like that effects
    certain system files.

    Yes. After further investigation, I've concluded this is the case, and
    there is no actual problem.

    On the time spent up-side, however, I've got rid of a vast amount of
    spy-bots, diallers and redirection crap.
