My acer notebook will not boot up.?

There's only one guaranteed procedure to remove any virus correctly and completely.

You must remove the hard drive from the system and use it as a secondary drive in a different system, or use a new drive in that system so the drive with the virus is NOT running the Windows that makes the computer usable.

You then must update the antivirus and ad/spyware definiton files to the minute on the running system BEFORE YOU ADD THE VIRUSED DRIVE TO IT. Once You have done the update, add the virused drive and clean it completely TWICE with both programs.

The next step gives You a cpl extra opportnities to avoid this problem again. You now have to delete and re-create the C: partition on the drive, which means You can also re-size it and create some additional smaller partitions for data that will stay secure during Your next virus problem.

You can also create an extra partition for the Windows installation files, and any software installers that You need to keep around in case of system failure again. This means that next time You can just delete the C: partition and restore Windows to it the use the files already on the drive to re-customize the system. asically a homemade recovery partition without the headaches the factory version had for security copying reasons.

You should also make a re-install partition large enough to store at least a single "system restore point", and even better 2 or 3. And keep in mind that Windows XP (all versions) had an unknown size limitation of 128Gbs per partition and would cause hardware problems above that size when they acessed data there.

So if You have a harddrive over 120Gbs, You should make at least the C: partition no larger than 128Gbs, and a 500Gbs drive should be split into a 128gb C', a 128Gb D:, and the rest for software and system restores.

Good Luck!

I would recommend an antivirus boot cd: http://www.howtogeek.com/howto/38889/how-to-use-th...

Also, I had an experience trying to clean someone's computer, it wouldn't start up in safe mode. Some research indicated that the virus had injected a fake driver into the c:\windows\system32\drivers folder. It's 0kb in size. Using a boot cd I was able to go to the folder, find the file in question (name is not important, size is), delete the driver and then was able to start up the computer in Safe Mode With Networking (for internet access), ran and updated Malwarebytes.

This is the CD I used. It has a few antivirus programs integrated into it: http://www.hirensbootcd.org/download/Hirens.BootCD...

So try after you log on, get into the Bios (F2 / DEL / F5, referto manuel), and then reboot off from a re-bootable disk or drive and then add AVG or something on that and then ddisinfectit. Make sure the re-bootable disk is read-only. (Floppy is good because you physically make it read-only by covering it my a sticker on the write zone)
