I have McAfee so did an update and full scan and it found nothing. I always use Ad-Aware and Spybot. Someone suggested Avast and it found nothing. A week later I was still having problems. Updated McAfee and went through two full scans and it found nothing. Someone suggested a program called AVG. I know I'm not suppose to run two different anti-virus programs at the same time, but I knew I had SOMEthing and was reluctant to disengage McAfee to run this AVG thing I never heard of.
As soon as I started the AVG program, I started getting pop-up notices from McAfee saying it found files infected with the Downloader-BEW trojan. AVG kept running, and McAfee kept finding them, alerting me, and deleting them. In McAfee's log files, the 'detector' listed for all these files was "AVG Anti Virus".
I went to McAfee to find out more about this trojan. It says it comes with a file called abc123.pid I searched my computer and it was still there. I went to their online helpdesk and was given instructions via email on how to boot to dos and run a full scan that way. When it was done, I searched for that abc file and it was still there, resting comfortably in my TEMP directory.
I went to their online help forums this time and was given a link to SuperAntiSpyware. I downloaded it and it immediately found a trojan it called downloader-gen/suspicious and it quarantined it. That abc123 file was still there, so I just deleted it myself seeing as no other program was.
I'm still worried that I might have something, since all I've read about this downloader-bew states that it sits in your TEMP files and if deleted it regenerates itself. It was suggested that I download and use highjackthis and post my log somewhere.
I read all the instructions here but must've missed whether I was to attach the log file or just cut'n paste it here. I went ahead and attached it.
