Cant re-install Win 7 64

AVG is crappy bloatware which no one here recommends. Boot WDO as suggested by Karl to run a full scan now. Then install Microsoft Security Essentials to run a full scan.

Post up the infection name in our Security forum for expert targeted scans to run.

Test your System Files for damage using SFC -SCANNOW Command.

Establish a clean boot now to kill all startups except MSE: Troubleshooting Steps for Windows 7

If you decide to clean install wipe the HD first using Diskpart Clean Command then Clean Reinstall - Factory OEM Windows 7 - everything you need is in the blue link to get a perfect reinstall. You must reinstall all programs.

This problem has got deeper and deeper. Overnight I ran three virus checkers.

AVG which picked up nothing
Windows Security essnetials that picked up numerous trojans around 30!
and malicious software removal which picked up 1

I ran the system scan and all was OK

However I checked my firewall and its disabled 0x8007024 error code comes up when trying to enable.

Clearly some people have been doing some really nasty stuff on my PC.

I have update my spec on the profile



I have downloaded the win defender and its on a usb but I dont know how to boot from it. When I go to Bios it gives me no (apparent to me) option stating USB.



Rather not wipe my PC it runs Cubase and thirty or so plugins some of which take a couple of days to install - orchestras and things. There is a lot of other stuff too like a decades worth of samples measuring a TB or so

Although IE 9 9.0.6 (KB2675157) is now working when I first load it gives a "IE is not working" type message and reloads the (innocent) home page. I have AVG do not track and Ghostery running.

Once again grateful for some quality help here.

So what have they told you in our Security forum when you posted up the trojan results from MSE scan? They should have given you specific cleaners to use. But an infection serious enough to disable the firewall will likely require a Clean Reinstall.

Computers cannot be handled like a hoarder with a houseful of stacked newspapers. It needs to have a perfect reinstall then be maintained perfectly. If performance slips or it's hit by serious infection then it needs to be wiped and start over. Follow the same steps for Clean Reinstall - Factory OEM Windows 7

The WDO stick must be written by the app correctly, plugged in, then tap the key for one-time BIOS Boot Menu at boot, F8 on Asus mobo's. Look under USB, Removable or HD's.

Why is AVG bloatware still installed? Do you ask for advice to ignore it, or are you here to benefit from experienced help recognized as the very best in the industry?
