Hi,

 

I run a small network of computers and I've recently had what might be a reoccuring infection. I'd love to discuss this with a knowledgeable person.

 

Several of the PC's users have been complaining that the computers are running slow. I didn't find anything with standard antivirus and malwarebytes but ran combofix and found the following file on the machines in questions (all XP SP3), which combofix deleted.

 

 

 

c:\documents and settings\All Users\Application Data\TEMP

 

 

Combofix deletes the file in question but combofix scans the next day find the same file. I've disabled system restore on the machines in question but the file keeps showing up on a combofix scan. I know a slow PC can be a real sign of infection, and this file keeps showing up, so I'm wondering if this is a legitimate infection. It's showing up on probably 4 or 5 XP PC's but not all of the XP PC's in our network. I'd really appreciate any advice you all may have. I've attached the latest combofix log from a scan I ran today.

 

Thanks!

 

Mark

Hi Guys,

 

I understand that you all don't recommend using Combofix w/o supervision. I also understand the risk I'm taking and I accept responsibiltiy for anything that might happen to the PC. The only reason I run it is Combofix seems to be one of the only tools that will actually remove some of the deeper malware and rootkit infections. Often I am out in the field and trying to fix machines for someone right then and there. People want quick resolution so I often don't have time to post questions and get help on these types of infections.

 

Is there another tool or software that you guys can recommend that could be used on one's own?  I am also looking for some good advice on software for prevention. Norton and a lot of the other A/V/malware scanners are pretty worthless when it comes to prevention and even detection and I want to be able to keep these things off people's PC's. I know they will continue to have trouble if they are doing p2p sharing, torrent downloading, etc but I have many people that are doing pretty normal web surfing that get infectied. Any advice on software to keep this stuff off the PC's?

 

Any help on this would be appreciated. I continue to have problems with the above issue as well. This is on a small business network and I've got a little more time to resolve things and flexibilty when I'm working with them.

 

Thanks,

 

 

Mark
