Slow computer...

I am working on a client’s computer that is very slow.  I have reinstalled IE, run Malwarebytes – it found Trojan.Vundo and lots of adware - ran Hitman Pro, CCleaner, got rid of troublesome programs, ran Glarysoft Disk Speedup to defrag, and went through startup and services.  Anything else you might recommend?

Need clarification....  

How was the performance immediately before the virus infection?

I would do a Read Only CHKDSK inside windows....



If it reports there are errors, or that it cannot continue, select "chkdsk /f /r", hit Y, and reboot. The results are in the Application Log, source Winlogon.

Also, run through this.....

How to check your DMA status & reset it if necessary

Now here is another possibility to isolate purely a HW problem or a SW problem. Build your choice of the following 3 standalone CD based OS'es, and run some of the stress testing utilities on it. If it is slow still, I would suggest hardware.

combofix works well on xp in my experience.
After eVeRything you have dOne to bring this unit back with no luck. I would recommend doing a fresh install of your O.S. This will be the only way to bring this computer back into it's best possible speed. Once you have a fresh install look into upgrading the ram and tweaking the O.S. EX.

themrrobert I've only used combofix a couple of times.  There are so many warnings about using it, it makes me nervous that it might cause problems.  How safe for guided use is it?  Does it need the internet to fully run?

Things are running faster...he has 2 g ram, lots for XP.  I don't have access to the internet right now on his computer so can't do a full test on all I have done.  I’ll know more on Monday.  I agree, if this doesn't take care of it a fresh install will be necessary.
may be run a registry defragmentation, and if possible, ask the client to add more RAM to the machine

>>  a client’s computer that is very slow  <<   thsi has many possible causes:
-malware, as you already looked into
-specs : cpu too slow for xp sp3, too little ram, disk full  --> post cpu, ram spec and disk size + free space
-software : OS corrupted, programs running in background (eg daily AV scan)
-hardware  : bad disk sectors, file table corrupted

as for now - i suggest to run a LONG disk diag; if that comes back OK, run chkdsk on it, and a defragmentation, that should take care of most problems
find here all disk diags :      
pick the one for your disk brand
go to device manager
expand - IDE ATA/ATAPI Controllers
delete primary IDE channel and Secondary IDE Channel.

Because due to disk error sometimes it goes into PIO Mode instead of DMA mode.

Hey John...I'm not sure when I got the virus, he didn't even know he had one since Norton did not find it.  I ran chkdsk.  looked good when I ran it...where do I find Application Log, source Winlogon?

When I checked the DMA there are 2 primary and 2 secondary IDE Channels...1 set looks set correctly.

I have a UBCD much on it not sure what to run.

CPU - Intel Core2 6300 @1.86 GHz
1.59 GHz, 1.99 GB of RAM
HDD 289 GB with 238 GB of free space

Need to run a disk diag

Application Log, and click the top of the SOURCE column, and it will sort the events for you...... Then just find Winlogon....

Here is the log John
No bad sectors, that was good... I would expect a little improvement as it did make some corrections?
MagsOwnerAuthor Commented:
Things are loading faster.  Not like new but we would probably need to do a fresh install for that.  Would you still recommend a Disk Diag or does the chkdsk do much of the same?  Should I run some from the UBCD disk?  Favorite tests?

What about the DMA?

Thanks for the learning lessons!
nobusConnect With a Mentor Commented:
run from UBCD - long test - pick the one for your disk brand, eg seagate for seagate disk
it won't harm anything - and it is better than chkdsk (which checks the file system)

nobus...that is what I thought after I thought about it for a minute...thanks for clarifing.  Went to run the long test...said to make sure files are backed up...exited to run back up.  Client says his files are backed up but I would rather error on the safe side and do a quick back up.

Is this over kill or a good practice when working on a clients computer?
nobusConnect With a Mentor Commented:
a backup is NEVER overkill; better have 2 than 1 which proves corrupt when you want to restore it...

Help!!  .Net Framework was corrupt so I uninstalled and reinstalled (per another EE solution) the version that was corrupt.  Now Media Center will not open, saying it needs an older version to run.  Is there any issue in installing that version as well...I was under the impress that the newer version was sufficient.
MagsOwnerAuthor Commented:
Computer up and running as well as possible without a fresh install.  HDD error free.  Thanks guys!
tx for feedback, and good luck with it
