I seem to have got a trojan or virus on my pc. Lately it has been running slower than usual and places I visit like ESPN.com will have pornographic images where automobile ads normally are located. Each day Windows Defender finds this file and no matter how many times I quarantine or remove it it keeps coming back.

I came here and followed all 15 steps as requested and am hoping for some assistance. Attached are the 3 log files requested.

Thank you in advance,
Turkishbull
 
Hello and welcome to Techspot.

Your system is infected with a trojan called Downloader.Agent.awf. It replaces legitimate files that are common on most computers with an infected file. Then, it moves the legitimate files to a bak or backup folder.


Very Important: Before deciding whether you should clean or reformat your system, go and read this thread HERE and decide what it is you want to do.

If after reading the above, you wish to clean your system, do the following.

Go and read this thread this thread HERE and follow the instructions exactly. Post the requested log files.

We need to temporarily disable Spybot search & Destroy`s tea time, as it may interfere with any fix we are trying to run.

Disable Spybot's TeaTimer. This is a two step process.
First:
- Right click Spybot in the System Tray (looks like a calendar with a padlock symbol)
- Choose Exit Spybot S&D Resident
Second:
- Open Spybot S&D
- Click Mode, check Advanced Mode
- Go To Left Panel, Click Tools, then also in left panel, click Resident
- If your firewall raises a question, say OK
- Uncheck the box labeled Resident Tea-Timer and OK any prompts.
- Use File, Exit to terminate Spybot
- Reboot your machine for the changes to take effect.


You might want to copy and paste these instructions into a notepad file. Then you can have the file open in safe mode, so you can follow the instructions easier.

Boot into safe mode, under your normal user name(NOT THE ADMINISTRATOR ACCOUNT). See how HERE.

In Windows Explorer, turn on "Show all files and folders, including hidden and system". See how HERE.

Delete all files in AVG Antispyware quarantine.

Go to add remove programmes in your control panel and uninstall anything to do with(if there).

That all looks good.

Unless you`re still having problems, you should be good to go.

If you`re not having any problems, please do the following.

Turn off system restore.(XP/ME only) See how HERE.

Now, turn system restore back on. This will have deleted all your old restore points and any nasties that are in them. It will also have created a new, clean restore point.


If you have any further virus/spyware problems, please post in this thread.

Thanks a bunch for your help. It was gone for about 2 days then resurfaced yesterday. I'm going to try following the same steps as before and see if I can get rid of it again. If not I'll post here for additional help. It was much appreciated the detail and time you took to respond previously.
