Two days ago Avast triwd to update but there was an error. I rebooted my computer to scan on startup and after that no programs work. IE Chrome FF and Avast will not stRt up. Any ideas?

welcome to the forum.
i suggest you try to repair avast as a first option.
go start/ controlpanel/ add/remove programs, scroll down to avast and hit the remove button.
a new screen should come up, from there hit the repair option.
if this should not work.
try a installation from scratch.
good luck

I can not download anything as not browsing works.
Try this : Start Menu > Command (run as admin) > type in SFC /SCANNOW and run that which should deal with the corrupted files.

As AdrianH posted above please run the SFC repair, Start Menu > accessories > Command Prompt - right click (run as admin) > type or copy in SFC /SCANNOW and click enter, this should fix your problem.

Are you able to get to safe mode ? if so then open up computer and right click on C drive\properties\tools check drive for errors and tick both boxes then click start and you will then be asked to reboot, try that and let us know how it goes.

Safe mode does not work. No repair option. And system recoveries does not work.

I would normally refer this to essexboy now but he's away till the 6th of october so hopefully someone with a bit more knowledge can shed some light on this for you.

I dont think its malware vut I will try them.

Even if it's not malware the team over there will be able to get you sorted and your system at least up and running, might also pay to include a link to this thread for them to follow up what has been going on with your system.

Turns out I am required to dowload something and I cant get pass the black screen.

Sounds like your bootloader is corrupted. If your OS is WIN 7, you can try the repair option from the installation CD. Do research this first before trying.
Is the screen totally black or are text messages being displayed once you attempt to boot into Windows? If messages are shown, write them down and post to this thread.

Unfortunately, I do not havemy cd with me and a need a solution that can fix it asap because I require my computer for school.

What ver. of Windows do you have?

Windows 7 home premium x64

Are you sure Safe mode does not work? Tap the F8 key as the PC boots.
If you can get into Safe mode, then check your graphics drivers in Device Manager. Many black screens in Win 7 are causes by corrupted graphics drivers.
-
Safe mode doesnt work...
Goes after windows logo, it goes black screen.
-
Sounds to me your only option left is to try a repair from a WIN 7 Premium x64 installation disk. Try to see if someone has their disk at your school. Make sure you know your product key before doing a repair since it might ask for the product key.

I have the key. I will ask around. Would it be better to ask for upgrade or full install?
-
If you using an upgrade disc i dont think there was a repair function with that, you need the full disc of the version that is already installed on your system or a system repair disc that hopefully you created when you first got your system.

Okay. I wull try that out eventually.

Make sure when you do select the repair option from the installation disk, you first try the option to repair your start up files. I have run that a couple of times sucessfully when I borked my boot loader files when I was fooling around with my dual boot XP and WIN 7 setup.
Do make it a point in the future to create a WIN 7 recovery disk and keep it always with your PC for instances like this.

I will keep that in mind in the future. If my HDD is not fails its scan, does that mean I should still repair?

If my HDD is not fails its scan
Are you now running HHD diagnostics using a bootable CD? What is the result? Are you getting SMART errors?
HDD errors are an entire different issue.

I go into the BIOS and I run the HDD diagnostics test and it always fails.

It still goes to the black screen even when I am using the qindows disk. It goes to either Safe mode or run normal options when first booted. After choosing, it goes to the windows logo and then a black screen with the mouse.
-
I solved the last prob because my laptop had usb cd drive. But now there is no repair option available. So how should I procees?

Originally you said you couldn't boot into safe mode. Later you said the above. If you can boot into safe mode, go into device manager and check out your graphics drivers. Personally I think that is your problem. You can always uninstall the existing graphics drivers and reboot. Win 7 should find drivers for your graphics drivers and reinstall them; at least the drivers that were current for the WIN 7 ver. you have installed. If that cures your normal boot problem, you can them install current drivers for your graphics card.
Another option is to try a system restore from an archive prior to when your problems started. Not always works and can make matters worse.
If the above don't work, I am out of suggestion other than take you PC to a pro for repair or reinstall WIN 7. If you reinstall Win 7, you can backup all your important files from safe mode prior to the reinstall.

I never said safe mode works... if I did or there was a misunderstanding, I am sorry. But safe mode does not work... goes into black screen after winfows logo.

Let's back up a bit.
First, you need to determine if your HDD is failing. I don't know what BIOS checks you are running. I have built multiple PCs over the years and the only BIOS option I am aware of is tuning off/on SMART checking. I do recollect a few BIOSes that display SMART status info. Is that what you are referring to?
The only approved way of determining HDD status is first determine who the HDD manufacture is. Next download the manufacturer bootable diagnostic CD .iso image and burn the .iso image using burning software capable of created a bootable CD e.g. Nero, Roxio, WIN 7's CD/DVD creator, etc.
Then boot from the CD ensuring your BIOS options are set to boot from CD/DVD drive first or press the appropriate select boot option key when the BIOS splash screen appears. Run a quick scan from the HDD diagnostic program. If no errors are found, then run a full scan. Note that a full scan on a large HDD could take many hours.
If no errors from the above steps are found, your HDD is not the problem. If your HDD is defective, you need to have it replaced and then reinstall WIN 7 since your don't have an image backup of your existing HDD. A repair shop might be able to recover your existing data but be prepared to pay a large sum of money for that effort.

Well, in the bios there os a option to scan memory or hard disk. I presser hard disk and it failed the test.
-
I suspect the BIOS test you are performing is a SMART test.
My expeience is that SMART checks from the BIOS are not always reliable. Best you run the HDD manufacturer disk diagnostics.
Again you need to get this resolved before you do anything else.

For what it's worth...
I have been getting the same black screen and cursor that lhui describes on my Win 7 32bit PC ever since I upgraded to Avast 6 Internet Security some time ago. I have both a user account and admin account which are password protected. The black screen occurs after the login screen appears and I enter my password and then hit enter, it is as though something is interferring with the loading of the desktop. I have the boot time & PUP scan enabled.
If I wait approximately 20 seconds after the login screen appears until the hard disk activity starts decreasing, and then enter my password and hit enter, the system continues to load my desktop and all is well. With the boot time & PUP scan turned off, I don't need to wait until the hard disk activity decreases, I can just enter the password, hit enter and my desktop loads without a problem.
I am wondering if lhui has the boot time & PUP scan enabled and if maybe it is that that is causing the black screen and cursor, as in my case.
