Access denied everywhere and low memory warnings

Some Trojan:Win32/Malex.gen!E infections contain trojan and keyloggers which can be used to steal sensitive data like passwords, credit card, bank account information etc. You will need to change all your passwords using a 'clean' computer, not the infected one.

Let's flush the dirty DNS cache and restore MS's Hosts file:

Copy and paste these lines in Note pad.

@Echo on
pushd\windows\system32\drivers\etc
attrib -h -s -r hosts
echo 127.0.0.1 localhost>HOSTS
attrib +r +h +s hosts
popd
ipconfig /release
ipconfig /renew
ipconfig /flushdns
netsh winsock reset all
netsh int ip reset all
shutdown -r -t 1
del %0

Save as flush.bat to your desktop.
Vista and Windows 7... right click the .bat file and choose to run as Administrator. Your computer will reboot itself.

Next, download Combofix from any of the links below, and save it to your desktop.<--Important

Click on this link Here to see a list of programs that should be disabled.
The list is not all inclusive. If yours is not listed and you don't know how to disable it, please ask.
If your anti-virus or firewall complains, please allow this script to run as it is not malicious.
Next: Disconnect from the internet. If you are on Cable or DSL, unplug your computer from the modem.
Next: Please disable all onboard security programs (all running with back ground protection) as it may hinder the scanner from working.
This includes Antivirus, Firewall, and any Spyware scanners that run in the background.

• Double click combofix.exe and follow the prompts.
• When finished, it will produce a log for you. Post that log

Note: Do not mouseclick combofix's window while its running. That may cause it to stall
Please be patient while the scan runs, at times it may appear to stall.
When finished and after reboot (in case it asks to reboot), it should open a log, combofix.txt.
After rebooting ensure your Security applications have been re-enabled.

IF CF won't run:
During the download, rename Combofix.exe to sVchost.exe

If you can, download it to a 'clean' flash drive, then change the name.
Next: Disconnect from the internet. If you are on Cable or DSL, unplug your computer from the modem.
Plug the flash drive in, right click and choose "run as Administrator".
