My friend's laptop has a problem with error messages that keep popping up during startup. And also, everytime he tries to open a file or program, it will ask to Open With. Is there anyway to overcome this problem?

Here's what happened to his laptop recently.

Recently, a huge amount of trojans attacked his laptop. He managed to clean them using Super AntiSpyware but three still remained. It keeps popping up in the scan and in real time scans too. After that, he didn't touched the laptop for a while and when he finally did, the trojans dissapeared. But when the trojans "dissapeared", the messages start to come up.

It's starting to get really annoying with the Error messages and the Open With messages. Is there anyway to solve this? Most of the error messages says "cant find" or "cannot find". Also, when he clicks properties on the desktop, an error message says "Cannot find C:// System 32/ rundll32.exe " (it's not exact but that's what it is)

So, is there anyway to remove this messages? It would be great if it was done by today. Thanks in advance.

Hello, please note I'm not a staff member here, but perhaps I can help get started.

I'm thinking those trojans didn't just "disappear", but might still be active and making trouble on your friend's machine. Do you have any of the logs from SAS or the other scans that show what the three persistent entries were?

I'd also suggest running a scan with RootRepeal to look for hidden entries. There's a guide to running it here (by Blade):

Hi there JackRipperz.

Before we begin, I would like to clarify something. Regarding the topic you posted in the Windows XP forum, I believe it is a separate computer than the one we are dealing with here, as you mention this is your friend's?

Anyhow, the issue you seem to have is something related to the registry. The infection was not remove completely, and somethings seem to have not been dealt with successfully.

A couple of questions:

1) What programs do you open give you this message? Is it all .exe programs that happen? What specific file extension that you can't open?
2)

Also, when he clicks properties on the desktop, an error message says "Cannot find C:// System 32/ rundll32.exe " (it's not exact but that's what it is)

Can you confirm the exact error, when it happens again?

Let me know.
Note: Please do not PM me asking for help, instead please post it in the correct forum requesting for help. Help requests via the PM system will be ignored.
