Technical Support

If you have a technical problem with any of our products, the avast! support team are on hand to help you resolve them.

However, we would ask, before you contact the avast! support team, that you first read our Installation Guide, check our FAQ (frequently asked questions) section, or visit the ALWIL Software Forums. As many problems have previously been resolved, this could be the quickest way to find the solution.

The most effective way to contact our technical support department is by sending an e-mail to support@avast.com. Please note: we can only respond to emails that are written in the English language. Correspondence sent in any other language cannot be answered at this time, however, we have a network of resellers, partners and distributors all over the world, many of whom also provide local language support in their territory.
In any email message, please supply the following information:

What operating system are you using? (e.g. Windows 2000 Server...)
What version of avast! are you using? (e.g. 4.0.160 - you can find this information in the "About avast!..." dialog)
What version of VPS file are you using? (e.g. 0303-10, 04/15/2003 - you can find this information in "About avast!..." dialog)
What is your basic hardware configuration? (e.g. Intel Pentium III 800 MHz, 128 MB RAM)
How do you connect to Internet? (e.g. dial-up, using a proxy server, using a firewall...)
What is your e-mail client? (e.g. Outlook, Outlook Express, IncrediMail...)
Do you use other security software? Which one? (e.g. Norton Antivirus...)
What are the steps to reproduce the bug again? (such as what was the system doing at the time of the problem...)
Do any error messages appear? If yes, what exactly do they say?

If possible, please also attach a screenshot of any error message.

Telephone technical support is provided for commercial users only. Home users can take advantage of our FAQ , forums or ask for help via e-mail.

If you have any suspicious files that are not detected by the latest version of our antivirus programs, you can send them to virus@avast.com. The ideal way to send such files is to compress them as a ZIP with the password 'virus' (so that the attachment is not deleted by some other antivirus software on the way).
