-====== How to clean up spyware and viruses (virii?) ====== 
  
- 
-This is the general process I currently follow to clean up a spyware/​virus infested computer.\\ ​ 
-Obviously this can be changed to suit your preferences/​situation.\\ ​ 
-I welcome any suggestions for other free programs to add to the toolkit.\\ ​ 
- 
-Note that some of these have commercial versions and some that don't have a place to donate, so if you find yourself using these on your own machines regularly, you might want to consider supporting the developers.

-===== Programs I Use =====

- 
-===== Typical Procedure ===== 
- 
-I will typically run each program several times until it either doesn'​t find anything, or until I find that it is finding something that it can't remove.\\ ​ 
-I will usually skip to HijackThis and SystemRescueCD if this happens and try to remove the deep infection before moving to the next scanner in the list. 
- 
-   I. Download all programs 
-   I. Install all programs 
-   I. Run AVG Anti-Rootkit 
-   I. Run AVG Anti-Spyware 
-   I. Run AVG Anti-Virus 
-   I. Run Spybot S&D 
-   I. Run Ad-Aware 
-   I. Run HijackThis 
-   I. Run SystemRescueCD 
-   I. Wash, Rinse, Repeat as necessary 
- 
-===== Details ===== 
- 
- 
-==== AVG Anti-Rootkit Free ==== 
- 
-I figure this is the proper place to start, since rootkits are very dangerous and can be used to load other nasty things. 
- 
-==== AVG Anti-Spyware Free ==== 
- 
-Next we scan for spyware, tracking cookies, etc.  and delete/​quarantine everything found.\\ ​ 
-Note that you need to check the default selected action in the list for things as some spyware programs default to Ignore Once instead of delete/​quarantine. 
- 
-==== AVG Anti-Virus Free ==== 
- 
-Now we run a full system virus scan.\\ ​ 
-Make sure to change the Complete Scan settings to scan All Files to be safe. 
- 
-==== Spybot S&D Free ==== 
- 
-At this point the <​del>​victim</​del>​ patient should be mostly or completely clean.\\ ​ 
-However, we can never be too sure as often one scanner will catch things another doesn'​t.\\ ​ 
-When setting up Spybot S&D, make sure to *enable teatimer* (and teach the user to use it properly) and *immunize the system*.\\ ​ 
-You need to re-immunize after updating Spybot S&D to protect against new threats.\\ ​ 
-These will help immensely in keeping the system from being re-infected. 
- 
-==== Ad-Aware Free (Personal) ==== 
- 
-One more scanner to make sure we really do have everything found. 
- 
-==== HijackThis ==== 
- 
-If you are at this point, the computer is/was probably in bad shape.\\ ​ 
-HijackThis is a deep scanner that lists programs running on startup, browser plugins, etc.\\ ​ 
-It is a valuable tool for removing some deeply hooked spyware.\\ ​ 
-This is not to be used carelessly!\\ ​ 
-There are several forums where you can post your logs if you are unsure what is safe to remove. 
- 
-==== SystemRescueCD ==== 
- 
-SystemRescueCD is a Linux LiveCD that has a multitude of useful programs and boot images.\\ ​ 
-This CD is a core part of my IT toolkit.\\ ​ 
-Typically I use this for virus scanning the host if a virus scanner won't run in windows, manually deleting files that the windows programs can't, and for backing up and restoring data or partitions when needed.\\ ​ 
-Note that it is fairly easy to build a customized version of this CD or to make a DVD (simply follow the procedure for a custom CD but burn to a DVD instead - this gives you space for extra stuff like windows utilities or disk images).\\ ​ 
-There are also instructions for setting up a USB device (flash drive/hard disk) to boot SystemRescueCD (I have done this with my flash drive).\\ ​ 
-Just remember that the computer needs to be able to boot the disc/USB device.
