Never cared for doing them from inside Windows and if the system crashes and you have to Load an image back on a wiped drive you'll need to do that from a Boot DVD or USB stick anyway. I Image my Boot drive, a SSD and temp store it on another internal drive. This makes making the image very fast, maybe 10-15 minutes tops. But that all depends on how much data is on the drive. Once the imaging is done I reboot into Windows and copy the new image over to an external drive.
this is over my head. I cannot follow what you are doing here.

As marmimar has mentioned ESET Online Scanner and Windows Defender Offline they are very good and would also be my recommendation.
I would not do a backup until you at least use EOS and WDO. You don't want to back up a infected system.

I did a clean install following the instructions given to me here at the forum. i went to digital river and downloaded on to a dvd, a win 7 iso.

after that I took my computer to my tech (because I could not get the wireless going). he replaced the wireless card.
I am not sure if he did another clean install or not. he might have.

anyway, with all of that said, do you think that I still have a rootkit on my computer?

No I don't. A clean install should of taken care of all infections. Just remember anything that you backed up from that infected computer could also be infected. If you install them on your new Windows install they could infect it. Rootkits are the baddest of the bad boys when it comes to infections. Another little thing. One of the best ways to get a rootket is using torrants and P2P.
Happy computing with your fresh install.

If you're absolutely sure that your computer was not infected AFTER you did the clean install it should be OK. If there's any chance you picked up any kind of malware and if you're absolutely sure your tech didn't accidentally get malware on your machine ... well, if there's any doubt in your mind another clean install might be warranted.

Without getting overly technical, a system image relies on a special program. That special program is what males a copy of the hard drive and lets you save it to another location. Most people recommend an external hard drive that connects to your computer with a USB cable. That external HD can be kept in a secure location until it's needed again. (Other people might say you can use CDs or DVDs and they'd be correct. But let's say you have just 20 gigabytes of data that you need to image. You'd need about 25 CDs or 5 DVDs to make the image. Way too many to guarantee that each CD or DVD will be correctly burned, not to mention the cost. That's why an external hard drive is the better choice.)

Windows 7 has its own special system image program already available. If you click the Start button and type backup in the search box you should see Backup your computer in the upper panel. If you click on that a new screen opens that looks like this:

trojan rootkit  and virus prevention-backup.jpg

In the left column you can select Create A System Image or Create a System Repair Disc. Again, the image is like a snapshot of your entire hard drive. The repair disc is a special CD/DVD/Flash drive that you can make that will allow you to boot your computer if Windows 7 ever crashes and you can't start the computer normally. It's a good idea to make this disc, especially if you don't have an installation DVD. Even if you do have the installation disc what if it gets lost or damaged? The repair disc is cheap insurance.

Before you make your system image you'll want the external hard drive plugged in to your computer. When you click on Create a system image your computer will automatically search for the external hard drive. When it's found you will be asked if you want to continue making the image. If you say yes you will then be told how much space will be used on the external hard drive. If you still want to continue the system image will be created with nothing else required of you. Sit back, have a beverage of choice, and in about 30 minutes (maybe a bit longer depending on how many gigabytes of stuff is being copied) you'll have your brand new system image on the external hard drive.

For more technically advanced users there are other options available and other specialized programs that can be installed to make the system image. But for average users the Windows 7 imaging program is more than sufficient. Hope this quick imaging lesson encourages you to protect your computer

thank you very much for your indeed excellent informative reply.

I never go to torrant sites. what is a P2P site? I never play games at all. is that what you mean? or are there other ones?

marsmimar,
do you (or anyone here), know if it would be ok (or advisable), to make system images of my laptop and my desktop computer on the same external hard drive?
