I accidentally opened a trojan on windows XP. How to proceed?

Question

I don't really need to remove it. It's ok if it just doesn't open anymore. Is there a program to remove all unwanted autoruns from registry ?

Answer 1

Free, and works well - Microsoft Security Essentials

Answer 2

Since you are telling it is a trojan . Use kaspersky internet security trial version and also use malwarebytes trial version. Scan with both of them.

Answer 3

hi you can use Kaspersky Poratable Edition, as you can run without installing it. it will help you, as some of the trojans will block installed antivirus program to run. so this portable version will help you to remove your trojan.

1. You can view what are all the programs are running as pc starts by using Autoruns Autoruns: MS SysInternals.
2. Use ProcessExplorer Process Explorer to check which process is running, and kill them if you feel suspicious about it.

Answer 4

Give Windows Defender Offline a try. You will need to create a cd/dvd or bootable thumb drive to use it. Once you create it, boot your computer from it and scan and repair your system.

Answer 5

I'd use the latest Restore Point (the one before you ran that trojan) -- type in System Restore in search to see all your restore points. (Back up important files if your restore point is too far in the past.) When everything is restored, I'd download Malwarebytes Anti-Malware, boot in a safe mode and run the whole system scan with it. You don't really need any other anti-virus programs...
