Sadly, no one can really come up with a super, fixer-upper computer procedure. Everyone uses their computers for different reasons and it takes time for a professional to figure out what the user needs, is accustomed to, and what the user can learn.
In that TFP thread I linked is a description of how to use Hijack-This! by Cynthetiq,
http://www.tfproject.org/tfp/2473635-post71.html . You can download Hijack-This! from Filehippo.com
Download HijackThis 2.0.2 - FileHippo.com . Install it, run the scan and create a log file. You can post the log file here and we can look at your computer's processes.
In the mean time, I suggest you visit PortableApps.com (
PortableApps.com - Portable software for USB drives) and get some essentials from there:
* Firefox Portable --
Mozilla Firefox, Portable Edition | PortableApps.com - Portable software for USB drives -- a browser independent of Windows. Look for the NoScript and Better Privacy add-ons for Firefox. NoScript prevents flash- and java-based web elements from running without confirmation. Better Privacy deletes the temporary flash cookies that get left behind, ones Ccleaner
doesn't even get
* Pidgin Portable --
Pidgin Portable | PortableApps.com - Portable software for USB drives -- a multi-protocol instant messenger. Works with AIM, MSN, Yahoo, pretty much everything
* ClamWin Portable --
ClamWin Portable | PortableApps.com - Portable software for USB drives -- a manual antivirus scanner
* Command Prompt Portable --
Command Prompt Portable | PortableApps.com - Portable software for USB drives -- a command line window independent from Windows
Since all these programs are portable, they can be "installed" (technically extracted, like a ZIP or RAR archive) anywhere and run from there--even USB flash drives. I say make a folder on your C drive called PortableApps.com and direct the installers to extract the programs there. You need only click on the AppNamePortable.exe and it runs from there. Move the folder, and it still all works. There is nothing inherently safer to using PA.c, but you can delete the app and get a new one if you suspect trouble. Applications from PA.c do not have administrative rights to run (in Vista) and can not do as much damage to a system.
