Can't run Virus or Spyware programs

I have been called to a friends to rescue their PC as they detected downloader.small and are having a a problem with a dialer.
I have been successful in the past at fixing many such problems, but this is a bit wierd.
I have deleted some suspiscious exe files with GIPO@MOVEONBOOT that kept appearing in MSCONFIG/STARTUP. The dial up box keeps autostarting even though it has been removed from start up.

Here is the problem.

The PC runs OK, until you run AVG or Spyware removal (including Search and destroy and many others I ogt from computercops.biz.

Then the PC reboots every single time during these scans. Is this a very clever virus? I can't find the name as the scans don't finish. I have run about 5 recommended spyware removal tools - they all cause a reboot half way through, or a cpl that don't detect anything finish but discover nothing (and ask for money to upgrade).

Any ideas?

Hi thanks for the tip, I close all applications, but I don't know what processes I should close and which I should leave open?
Is there a basic list of what i should leave on before the scan?

Many Thanks

 

I don't know what processes I should close

This may help to give some idea what processes are doing and if they can be disabled, scroll down to service configurations.
hope it helps

 

Thanks TonyT - it is XP Professional. So I iwll follow that advice.

I have noticed that these maliscious spyware, hijackers and diallers are getting out of hand - they seem harder to deal with than the "traditional viruses" and they are costing ppl a lot of time to fix.
I have also noticed that all the different spyware removal tools find totally different things. Even Adaware seems to miss loads of stuff other programs find and they miss stuff adaware finds - it's getting so difficult to control

 

In case anyone finds my results useful for future reference - here you go:

I booted into Safe Mode and ran SpySweepr, a program I am new to, but seems really good (it finds lots more than adaware does on my PC). The program ran and removed a few things. I then tried to run AVG (free edition) and it would not run in SafeMode - I even re-installed it and got the same error.

However, the SpySweeper run had cleared whatever it was that stopped me runnning AVG in normal mode, so I ran AVG that way and found a couple of viruses and removed to the vault.

I then scanned the secondary hard drive and found another group of viruses that AVG could not seem to deal with. They were in a hidden folder called Windows System Information (this disc used to be a system disk). I removed the viruses by deleting with Gipo@moveonboot as I could not delete them the normal method - access denied (Windows thinking they are in use).

System now seems clean

Anyone got a good recomendation for a Spyware program the stops these pests getting on the system in the first place? As opposed to cleaning once infected. I will try SpySweeper - but would appreciate some advice from the experts!

 

I use Spywareblaster with auto updates (paid version) and my Spy Sweeper, Ad-Aware or SpyBot never finds anything when I run the scans.

 

www.spywarewarrior.com is a good place to start when looking for recommendations. You might also note that some of the removal and preventions programs have to be run for each user or you risk reinfections.

 

Thanks for the replies - I will check them out. Need a free version really

I forgot to mention - I turned system restore off - as I suspect this may have had something to do with the re-infection. Is it safe to turn back on once system appears clean?

 

If you are sure that your clean. A program that I use to backup the registry at different points during a disinfections is ERUNT found here http://home.t-online.de/home/lars.hederer/erunt/ you might want to check it out. It is an emergency registry recover tool. Very simple, very helpful.

 

I just realised - you have to pay to update the definitions on SpySweeper - guess I'll have to try something else as I can't afford more software bills!!!

Shame - it's a nice program.
