Cannot run HiJackThis.....its locked after the first time...

Hi,
I am having a ton of problems. I have inherited this pc from my future mother-in-law. when she gave it to me it wouldnt even come on. I have made it this far but it is still infested with trojans, malware, spyware and bout every other "ware" you can think of. I cannot run ANY anti-spyware or anti-malware programs. This includes malwarebytes anti-malware, hijackthis, avg, etc, etc. If i download any of them they will d/l and i can run the .exe file once. The pc will then immediately stop the file after a sec or 2 then i cannot reopen it. Says i have no permissions. If i go to program files and look in folder properties all the folders that are anti-virus or anti-malware type change to read-only permissions. Im sure this is due to something or several somethings on here but im clueless......please help....my fiance is driving me nuts to fix it!! Thank you for your time.

Sincerely,
Brent D

We understand that you are having difficulty running certain programs, including HijackThis. However, in order for us to help you it is necessary that you provide us with a HijackThis log, and it is possible you may be able to trick the malware into letting you do this. First, download HijackThis to a clean computer, then rename it from HijackThis.exe to any other name you want, using an .exe extension, for example... YourLastName.exe. Once you have done that, burn it to a CD (preferable to using a flash drive that may easily become infected) then transfer the renamed file to the infected computer and run a scan, then start a new topic and include your HijackThis log. (Just follow the guideline at the link below to start a new topic and post your HijackThis log). If you are unable to create and post a HijackThis log, then your only option may be to reformat your computer and reinstall the operating system.

From your description of the problems besetting this computer, it appears to be badly infected; therefore, a reformat and reinstallation of the operating system is probably your best option as that would allow you to start fresh with a clean, malware-free computer. Hopefully, your future mother-in-law has the installation disks, or the computer is equipped with a restore partition.

This topic is now closed. Please start a new topic by following the HijackThis Guideline posted here, just be certain to rename HijackThis: >Guideline for posting your HijackThis log<
