'What are our options?'

They both started to look around to try to find some way of contacting the control room or tell them what was wrong.

'Sir, I think I have an idea'

'What is it Carter?' he asked looking suspiciously at her.

'There is an air vent up there if I could get into it I think it leads to the control room'

He was very skeptic about letting her go up alone, she had quite the bruise on the side of her head, 'Carter are you sure your up for this?'

'It doesn't matter if I don't get up to the control room fast then the virus is going to spread throughout the base and even onto the surface' she wanted to do this 'I can do this sir'

'Ok then Carter let me help you up'

It took around 10 minutes to move everything out of the way so she could get into the vent, standing on two tables and small box she managed to get up there and was just crawling into the vent.

'Good luck Carter' he said wondering when he would here any information back about what was happening so far.

Carter was crawling along the vents, it had taken her half an hour to get to the top so far and she was feeling dizzy again.

'Maybe I should have let the colonel go'

All of the air vents were part of the electronic system as to when they would be opened, the base on all of them could be opened if someone wanted.

She could hear the buzz of the control room which was underneath her.

She started to hear a hissing noise, the panel underneath her was opening, before she new it she was falling again.

It took her a while to realize what had happened, she had landed on her left arm unfortunately and could not move it. She could hear someone shouting her.

'Major Carter are you ok?'

She thought she should move quickly and sit up before everyone in the control room started to get worried.

While she was started to get up she cried out in pain, her arm we in agony.

'Are you injured Major Carter?' that sounded a lot like Teal'c she thought.

Before she knew it he was lifting her up and helping her move her arm into a comfortable position.

'Teal'c am I glad to see you, I think there is a virus in the computer system.'

'That's what we expected when none of the computers were responding'

She took a seat near the computers and was typing through everything when a code came up on the computer, 'It's the replicators'

Teal'c came over to look at it but did not understand it.

'They must have found our gate address and transferred a virus hoping to keep us out of the way' she was still looking at it, 'I don't know how to fix it'

General Hammond had come into the control room not realizing that Major Carter was there and asked for a damage report.

'Well sir a virus has taken control of our systems, it's expanding and taking over more of them soon we won't be able to stop it'

'Major where did you come from? And why have you got blood on your face and holding your arm?'

'It's a long story' she replied

But Hammond was adamant that he wanted to know so he responded, 'we have some time'

'Yes sir, I was in my lab with Colonel O'Neill just before the power went out, I wasn't feeling well this morning and got up to fast and collapsed, when I went down I hit my head on the chair'

'What is wrong with your arm Major?'

'When we couldn't get out of my lab I volunteered to try to get to the control room through the vents, when I got here the virus must have sensed that I was coming to try to stop it and one of the panels opened from under me and I fell to the ground, I fell on my arm sir'

'I will have someone bandage it up then once this virus has been destroyed you will be off to the infirmary.'

'Yes, sir'

After her arm had been bandaged she was at the computer screen again

'Sir I think I have something' when Hammond came in she continued 'if we shut down all the systems one by one the virus will end up in one place, if we can control it so that it is in someone's e-mail then we can destroy it'

'Excellent job Major'

'All I need to do now is to-'

Then it went black
