can't start after AVG update - is it a virus?

The computer repair store is telling me that I have a virus based on what I described above that occured after installing AVG update. I have Dell E521, Windows XP Operating system. I run an AVG scan daily and have never had any problems with my computer prior to this incident, nor have I had any virus activity reported after the AVG scan. Is it a virus or not?

Fake Antivirus Trojan...

I can't say for sure but the update you installed probably wasn't AVG.

I have has a half dozen people in the last couple of months have this fake antivirus trojan. They get some message about needing to update or run their antivirus and then everything goes wrong.

If you can do it, download and run SuperAntiSpyware in safe mode.

It's pretty good at finding this.

Here's some info that may help...

If you can't get into your computer and don't have a back up you may have to create a Ubuntu system disk on another computer boot your computer from it back up all your files and then do a clean install of Windows.

This thing can be very hard to get rid of.

Thank you for taking the time to respond to my problem, I ended up bringing the computer in for repair. I appreciate your comments.

Firstly to check if there is any virus present on the drive check it with AVG Rescue CD:

Afterwards, find your Windows XP installation CD and get into Recovery console. Then try to use "bootcfg /rebuild" command.

Please check following related articles:

If this does not help, could you please provide us with more of the error messages displayed when you are trying to boot to safe mode?

thank you

I ended up bringing computer in for repair. I still have a question about why an AVG update would trigger such a response. Have others had similar problems OR do you think it could have been a phony AVG message that caused the virus?

Just sharing.

I've found malware that tries to interfere with antivirus apps and the results can be like you read here. It's an interesting discussion about some of today's users asking for protection software that will guard against all malware and more but today there is no such protection. Our best defense is us.
