Please help me remove a Trojan!

I crack myself up!

Seriously, one of my older computers is infected with a trojan. It appears to be Win32/Sirefef.AC

It uses Windows XP and Firefox if that matters. I am nearly computer illiterate so any help would be appreciated.

Thanks.

Have you run Malwarebytes?

This.

I forgot about them. I'll give it a try.

I can't even open Firefox or Internet explorer

if you have a reinstall disc, then maybe it's time for a reformat/reinstall..

I've had a couple that disabled the browser as well. If you can download Malwarebytes on another computer, use a flashdrive to get it onto the affected unit. Just MAKE SURE to scan the flashdrive with any and all antivirus software before plugging it into any nonaffected PCs. Flashdrives are the dirty needles of the computer world when you're talking viruses.

You may also be able to download firefox to a USB flashdrive and run it from the flashdrive, but it may block that as well.

Safe mode with networking?

I scanned with Microsoft security essentials and it indicated that it removed the Trojan.

I can navigate normally here.

If I google Malwarebytes and try to click on the Cnet link, I get redirected to advertising. I've used Cnet before.

Have you tried flicking the tip to make the swelling go down?

Grab at the base and roll upward.

I downloaded Maywarebytes to a thumbdrive through a clean computer, but I cant get it to scan on the infected one. I immediately get Run Time Error 13 Type Mismatch.

Help!

Shut it down and start it in safe mode. That will load windows, but nothing else. On an XP computer if you shut it off while it's loading windows it will ask you if you want to run safe mode the next time you turn it on.

So are you saying turn it on and while everything is opening up, turn it off? I don't think I've ever seen safe mode listed anywhere (not that I've looked). Is that the only way to get into safe mode?

Yes, turn it on. When the loading windows screen comes up, turn it off. The next time you turn it on a DOS looking screen will come up saying it detected an aborted boot. It will ask if you want to start in normal mode, safe mode, and safe mode with the network. Start it in safe mode. The screen will look strange, it doesn't load anything other than the basic windows program. Any viruses won't have a chance to load. Then run Malwarebytes.

This is the only way I know to get it into safe mode. There are probably others, but I don't know them.

I had to do this to my netbook the last time it got corrupted. It's a bit of a PITA, but it worked.

Just hold down F8 while it's booting and you can get the safe mode menu. No need for any off/on trickery. (Specifically, press it just after the bios splash screen when it comes up with the "Starting MS Windows" text and the grey-on-black loading bar.)

I use "Combofix" from Bleeping computer with GREAT results.

Good luck Woody, I hope you get it off of there!

Also, I would disconnect the machine from the Internet while you do the scan.

No more trojans of any kind.
