    Hi all, :wave

    I hope you could help, because I am going crazy confused. I had discovered some trojans and tracking cookies that I thought I managed to delete using various programs such as AVG antispyware, Lavasoft Ad-aware, Aft Cleaner, Spybot, Panda Internet Security, Kaspersky online, F-secure, hijackthis etc. I decided to make a format with my restore CDs of Lifebook, in order to be sure that my pc was clean but after that avg-spyware found again a trojan.agent and some tracking cookies, even if i had only install the avg spyware. The same happened with Panda software and after formats with XP CDs and killdisk.exe
    Please help! I cant understand what's going on!:cry Is it possible to have a virus in by bios or something like that?What should i do to save my pc?:major

    Welcome to Majorgeeks!

    Notes:
    1. Cookies are not problems and you will always have them unless you never open a browser.
    2. It would be more help if you told us exactly what AVG was finding and where it was finding it. Just saying "trojan" is not useful since there are tens of thousands of trojans.
    3. If you have multiple antivirus applications installed (you mentioned Panda Internet Security and F-Secure) you must uninstall one of them. Only one antivirus application should ever be installed at any instance of time.
    Please follow our standard cleaning procedures which are necessary for us to provide you support. Also there are steps included for installing, renaming, running, and posting HijackThis logs as attachments.
    • Run ALL the steps in this Sticky thread READ & RUN ME FIRST Before Asking for Support
    • Make sure you check version numbers and get all updates.
    • Very Important: Make sure you tell us the results from running the tutorial...was anything found? Were you unable to complete any of the scans?...Were you unable to download any of the tools?...Did you do the on-line scans as suggested? etc.
    • After doing ALL of the above you still have a problem make sure you have booted to normal mode and run the steps in the below link to properly use HijackThis and attach a log:
    Make sure you also rename HijackThis.exe as suggested in the procedures. Use analyse.exe for the new name. This is very important due to some new infections going around.​
    • When you return to make your next post, make sure you attach the following logs and that you have run these scans in the following order too:
      • CounterSpy - only for Windows XP, 2K, & NT users
      • AVG Antispyware log - ONLY IF NEEDED you were not able to run CounterSpy. - only for Windows XP, 2K, & NT users
      • Bitdefender - from step 6
      • Panda Scan - from step 6
      • runkeys.txt - the log from GetRunKey.bat
      • newfiles.txt - the log from ShowNew.bat
      • HijackThis
    NOTE: You can only attach 3 files in a single message so it will require that you use two messages to attach all of these logs!
