I’m still learning Vista so at this point I’m just saying I think its normal/common. I know its not the best answer …
The list of tools that will run on Vista is rather short. Runscanner may help.
Download http://www.runscanner.net/download.aspx and install it.
Double click the Runscanner icon to run the program and choose Expert Mode.
Choose a Full Scan and click Start Scan. If internet access is requested allow it through your firewall.
When the scan is complete click Export .run File. Name it Runscan.run and attach that file to your next response. Also post the contents of the txt file log.
the trojan is called the JS:Agent Q{tr}
the url which i did not elect to go to but loaded up in tandem were at first http: //80.93.48.74/opiwecowebowi/ & http: //80.93.56.229/xurrvyqvswqcwq
I just got the same sort of detection while viewing a junk mail:
Hey man, check out these pics I took of my Ex-Wife. Man she was hot.
I knew this was going to be a page with a link to a virus, obviously!!
Agent Q seems to be some sort of exploit on the page, which has a download link not to naughty pictures, but to a malware file, msdataaccess.exe: the latest ‘Storm’ worm.
This one was not detected by avast! - emailed from the chest.
The moral here is don’t open junk mails which offer naughty pictures- the file will be a virus and the download page will try to nail you with an exploit.
