Changhed System files after update?

G

Guest

I shall explain step wise how things occurred:
1. Firstly installed Win Xp SP2 using a CD. (Fresh clean install)
2. Than installed AVG 7.1 & did a pre windows update scan, both the system
areas & whole machine. System was clean & system files ok.
3. Connected to the internet to auto update windows.
4. After downloading & installing all the critical updates, again preformed
a system scan which showed 3 system files being changed & no evidence of any
sort of infection.
5. By the way, am very conscious regarding security of my machine, so always
use Spy bot 1.4 & Ad aware SE Prof to scan & clean any spy wares or tracking
cookies IF ANY?
6. AVG system areas scan, when showed that these 3 files have changed, gave
me 3 options. Ignore, View file, confirm change.
7. Just to experiment I clicked on confirm change & the result was that Page
file got fragmented/ split into 2 parts.
8. I used Disk keeper Pro 9.0 by Executive as a defragmenter, which has many
options like MFT, page file defrag, boot time defrag, consolidation of file
folders etc.
9. Despite the page file getting spilt, the machine was working normally,
error free. But I could not defragment & compact the page file.
10. To clear my doubts I formatted & reinstalled windows again. But now
before updating, performed a pre update scan, went into the Sytem32 folder &
looked for the files. e.g. schell32.dll which was of 7.99 MB & the scan
revealed all these 3 files as OK.
11. After update the size increased to 8.05MB. So in a way AVG was smart
enough to pick the change.
12. My query is that were the original files updated OR new files installed
during update? If new were installed where the original 7.99MB shell32.dll
vanish.
13. Till now I do scan regularly for any virus threat, but don’t click on
confirm changes, as previously it split the Page file, although no harm to
the OS or its performance but doesn’t give me a peace of mind.
14. Now I am sure that file were updated/ changed/ increased in size, but my
query is why didn’t the auto update of windows make the change in the system
registry, coz as I initially manually clicked on confirm change, a change in
the OS registry was made resulting in split in Page file, which I don’t
prefer & have NOT DONE this time.
15. Can you come up with any logical answers, solutions, advice so that this
issue can be fixed, coz tweaking with windows registry is not some thing I
would like doing on my own.
16. At this moment I just have the windows & antivirus installed along with
the updates. This end user / stand alone machine is working perfectly apart
from the 3 messages which I get while doing a virus scan that the files have
been changed, which they have been.

Just 2 after thoughts that might be helpful in suggesting an advice, solution,
1. Is it technically possible & logical that if I copy/ burn these 3 system
files i.e. user32.dll, shell32.dll, and ntoskrnl.exe. & save them to a media,
after a fresh install & before going online to update the OS, & If for some
reason they again show changed after windows update, to replace the newer
ones with older??
2. Since my personal machine, as mentioned earlier as end user/ stand alone
system with a dialup connection, with NO net working/ work station/ server
function. So for security reasons I change some of the Services according to
my usage e.g. disabling Secondary logon, Remote Reg. Manipulation etc, before
going online to get the updates. In addition I do make slight changes in the
windows out look e.g. Classic type start up etc, all these after a fresh
install & before going on line.

Could this be the reason of the changed files?
Just a gut feeling!

user32.dll, shell32.dll and ntoskrnl.exe.

Some Windows Critical Updates install new versions of these files.

Thanks a lot, I appreciate your help.
The issue got solved. There is an AV7QDT folder along with programs &
windows in my computer.
Just deleted that & rebooted the issue is resolved & the scan NO longer
shows that the 3 system files are changed.
A few more small queries:
What exactly are the differences between Manual stopped & Manual but
started, Automatic & started & not started?
Can you please specify which ones to be disabled, set on Manual or Automatic
for an end user on a dialup?
How can one reach to the QoSRSVP utility in the windows?
Regards,
Waiting to hear from ya!

Ivanov,
What exactly are the differences between Manual stopped & Manual but
started, Automatic & started & not started?

Are you asking about services?
If a service is set to Manual and it is Started, it means that the system
needed that service for something. For example, Windows Installer service,
can be set to Manual and it will only run when you install or uninstall
something that needs the Windows Installer. Or, Background Intelligent
Transfer Service, if set to Manual, it should only run when you download
something.

Automatic usually means that whatever service automatically starts when
Windows starts. Some services may stop themselves if they are not needed,
even if they are set to Automatic.
Can you please specify which ones to be disabled, set on Manual or
Automatic for an end user on a dialup?

There is no magic bullet for which services are needed. All you can do is
look at some suggestions, study up a little and experiment a lot.

Here are some places to start.

How can one reach to the QoSRSVP utility in the windows?

As far as I know, QoS RSVP is just a service.
