Hi

I'm pretty much a novice at this. I run Avast, and it caught this virus apparently 4 times. They are in the quarantine chest. I have rescanned my laptop and it appears clean, but since the infection I cannot use IE7 and the laptop wont shut down properly after connecting to the internet although it does if I havent connected. I dont know if it is coincidence or related to the virus. I am currently using firefox. Also whenever avast tries to upate I keep getting an error message.

If it matters the system is windows xp.

Any advice will be most welcome.

Thanks Nick

Please describe specifically the error message you get from avast when trying to update.

When a program quarantines a file or moves it into a virus vault (chest), that file is safely held there (and no longer a threat) until you take action to delete it. One reason for doing this is to prevent deletion of an essential file that may have been flagged as a "False Positive". If that is the case, then you can restore the file. Doing this also allows you to view and investigate the files while keeping them from harming your computer. Quarantine is just an added safety measure. When the file in the vault is known to be bad, you can delete it at any time.

If the infection is not returning, try reinstalling IE7 before posting a hijackthis log and see if that corrects the issue.

Hi

The error message from avast when it tries to auto update was - "cannot connect to download43.avast.com". The number changes on each error message. If I try to update by clicking on it its says it "cannot connect to the server".

I uninstalled IE7 and reinstalled it but it still wont connect. I run the laptop via a couple of Netgear gadgets to the router and have never been able to go wireless with IE7. At the moment Firefox works both hardwired and wireless.

I have installed Sygate Personal Firewall. How do I know what to block and what to allow?

Since I did the two things above the pc is now shutting down properly. I dont know which it was related to.

Thanks
Nick

Your getting the avast error because you cannot connect to the Internet.

Most Internet connectivity problems arise out of corrupt Winsock settings due to the installation of a networking software or Malware infestation. However, since you have connectivity with FF, then the problem seems to be between IE and your Firewall and/or router.

Avast has auto updated a couple of times since my last post, so fingers crossed on that score.

Uninstalled IE7 again and whatever the default IE is on xp appears to be working normally.

For some reason I cant log a HJT at the moment. Will try again later.

Thanks for the help

Nick

Sometimes renaming the Hijack This.exe will allow you to complete a scan and log. Find the HijackThis.exe and right click on it. Choose rename and name it lastchancescan.com. then double click on it to run.
