Symptoms

by Charles Bundy In reply to how to find virus on my s ...

The only way I know to "find a virus w/o antivirus" would be to observe running PC, make note of odd behavior and go to a clean PC and Google.

If by "no antivirus" you mean the compromised system won't let you install or go to vendor websites, you will either need to:

1) Yank the harddrive and hook it up as a secondary device to a non-compromised system running AV
2) Create a standalone boot CD that allows AV to run independent of the OS on the suspect hard drive.

Solutions for that would be Avast BART (Bootable Antivirus & Recovery Tools), or AVG's RescueCD.

Know your systems baseline stats

by jdclyde In reply to how to find virus on my s ...

With Windows XP it was easy to tell if it was infected because more than 180 to 220 Megs of Ram was allocated BEFORE running your first application.

Haven't worked with new installs of Win7 enough to get a feel for it's baseline consumption, but I am sure it is out there.

To find a virus

by pacsoft In reply to how to find virus on my s ...

If you are running as a std. user/limited user and not administrator/root while you browse the web, insert a memory stick etc. then executables that are in areas where you can write to, are suspect. If you find executables in temporary files, My Documents or any such place, then study/disable those. (And please don't log in with admin/root rights till you have disabled those, as they might be running and waiting for you to do just that)

If you run as Administrator/root while you engage in risky behavior, then you need to see if there are executables in system areas, or if system executables have been altered. This is much harder.

Typically you'll see a same executable under many names, or you see a proxy server set up at local host (127.0.0.1), or some such, those are pretty suspect. You can use stuff to see if ports are being used and track to see why, some bad stuff needs to talk to a "mother ship" and you could catch them doing that.

If you know when it might have happened, search for files for that time span, sort by time/date and see if you can make sense of what you see. It is often really clear how an infection got in. You may have to do this from another operating system, such as Knoppix as a running contaminant can compromise the host O.S. to hide itself.

See what launches.

The worst are legitimate executables that have been altered. The rest is pretty easy.

Hope this helped.

you probably have a computer virus, if..

by anitalian0 In reply to how to find virus on my s ...

If your computer is acting strangely, running slowly or showing pop-ups that won't go away, you probably have a computer virus. Many antivirus programs are free to download and use, so you should always have one installed to prevent viruses and hackers from attacking your computer.

Instructions
1. Go to the website that offer software downloads and choose a free antivirus software from the list of software they recommend.
- Try <a href="http://spanish.200sharewarelinks.com/Windows/Seguridad-Privacidad/AntiVirus/AVG-AntiVirus-Free-Edition_4.html">AVG</a> Antivirus
2. Disconnect your computer from the Internet. Without an Internet connection, many viruses are rendered temporarily ineffective.
3. Open the antivirus software and click on the icon that allows it to scan your computer for viruses.
4. After the antivirus software has found the virus, it will eliminate it or quarantine it. Doing this makes the virus ineffective.
5. Keep your antivirus software up to date and running constantly in your computer's background. If it is disabled, viruses are able to get into your system.

Online Scan

by mrdood_99205 In reply to how to find virus on my s ...

There are a few websites that will help you with this. The 2 best for online virus removal are TrendMicro, and Symantec. Make sure your Java is updated first before you do, as both of them require Java scripting to run the online scans.
I suggest running Avast Home "Free" version, and Malwarebytes (also free). A very powerful solution "together" for fighting unwanted Bots, Rootkits, Trojans, Malware, Viruses, and other nasty software you run into.
