We will need more information to be able to help you:
- Which OS are you using? Is it up to date?
- What avast! version and VPS file (virus database) number?
- What was the filename and path where the virus was found?
- Which actions have you taken to try solving the problem?
- Do you use a firewall? Which one?
- Do you have any other antivirus installed in your system?
- Any other security programs?

General cleaning procedure includes:

1. Disable System Restore on Windows ME (http://support.microsoft.com/default.aspx?scid=kb;en-us;Q264887) or Windows XP (http://support.microsoft.com/default.aspx?scid=kb;%5BLN%5D;310405). System Restore cannot be disabled on Windows 9x and it's not available in Windows 2k. After boot you can enable System Restore again after step 3.

2. Clean your temporary files. You can use CleanUp (http://www.stevengould.org/downloads/cleanup/) or the Windows Advanced Care (http://www.iobit.com/AdvancedWindowsCarePersonal/index.html) features for that.

3. Schedule a boot time scanning with avast. Start avast! > Right click the skin > Schedule a boot-time scanning. Select for scanning archives. Boot. Other option is scanning in SafeMode (http://support.microsoft.com/default.aspx?scid=kb;en-us;315222) (repeatedly press F8 while booting).

4. It will be good if you download, install, update and run AVG Antispyware (http://www.ewido.net/en/). Some users recommend SUPERantispyware (http://www.superantispyware.com), Spyware Terminator (http://www.spywareterminator.com/) and/or a-squared (http://www.emsisoft.com/en/software/free/) (take care about false positives).
If any infection is detected, better and safer is send the file to Quarantine than to simple delete than.

5. If you still detecting any strange behavior or even you're sure you're not clean, maybe it will be good to test your machine with anti-rootkit applications (http://www.antirootkit.com/software/index.htm). I suggest AVG (http://www.grisoft.com/doc/download-free-anti-rootkit/us/crp/0), Panda (http://research.pandasoftware.com/blogs/research/archive/2007/04/27/New-Panda-Anti_2D00_Rootkit-_2D00_-Version-1.07.aspx) and/or F-Secure BlackLight (http://www.f-secure.com/blacklight/try_blacklight.html).

6. Also, if you still detecting strange behaviors or you want to be sure you're clean, maybe making a HijackThis (http://www.bleepingcomputer.com/files/hijackthis.php) log to post here and, specially, scan and submit to on-line analysis the RunScanner (http://www.runscanner.net/) log would help to identify the problem and the solution.

7. After you're clean, use the immunization of SpywareBlaster (http://www.javacoolsoftware.com/spywareblaster.html) or, which is better, the  Windows Advanced Care (http://www.iobit.com/AdvancedWindowsCarePersonal/index.html) features of spyware/adware cleaning and removal.

8. Finally, when you're clean, check for insecure applications with Secunia Software Inspector (http://secunia.com/software_inspector/) to update insecure applications and avoid reinfection.
