HijackThis not finishing scanning, very slow internet

Hi,

I'm facing a problem that I'm suspecting is malware related. Yesterday I tried to start malwarebytes but it wouldn't run (runtime error). Tried spywareblaster and also wouldn't run. I started HijackThis and did a scan-only but it wouldn't finish. It told me:

-----------------------------------------------
An unexpected error has occured at procedure: modMain_StartScan()
Error #5 - Invalid procedure call or argument

Windows version: Windows NT 5.01.2600 (I'm running XP, don't know if it's the same thing or not)
MSIE version: 8.0.6001.18702
HijackThis version: 2.0.2
-----------------------------------------------

I looked around and read somewhere a suggestion to update something (don't remember what) but after I did that, malwarebytes and spywareblaster started working again, but still the HJT problem persists.

In the meantime, my internet connection (wireless) has started breaking up, in the sense that it doesn't disconnect, but it doesn't respond either, webpages don't open, the small pc at the bottom right is not lighting up at all. This comes and goes (now it's fine). I don't know if these two are related. It is with great difficulty that I was even able to post this message, after several router and pc restarts.

Please help! Thanks in advance.

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.

Please 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.

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<
