False Positives It's important for you to know that
every antivirus program will, from time to time, find viruses in
files where there are none. When this happens it's called a false
positive. Avast has an outstanding track record when it comes to
avoiding these dreaded false positives. Norton has far more false
positives than Avast for example. In fact, in all the years we've
been using Avast, we've only seen this happen a couple of times.

Here are some tips for you:
1. If you
have a program installed on your computer and you've been running it
for some time without problems - the chances that a particular program is
going to suddenly become infected with a Trojan or virus is less
than your chances of being a passenger on the first commercial
passenger spacecraft to Mars. So, if you get a warning about a
program that comes from a reputable site and which has been
installed on your computer for some time and suddenly it appears to
be infected, don't panic. Use your head. Don't stick in the "vault"
- if you do, you're not going to be able to use that program.
Immediately think "False Positive"- and ignore the warning from your
anti-virus program. Always report the false positive to the maker of
the antivirus program right away so they fix it. Avast allows you to
report false positives from within the program. The sooner you
report it and the more people who report it, the sooner the program
will be fixed.
Here's how to report a false positive
in Avast -
1. Ignore the warning by clicking that
option in the warning window. A new window will open that will allow
you to report the false positive and submit a report for further
investigation. Use this option carefully - only use it when you're
sure that the program is one you're familiar with and one that has
been running on your computer for some time without problems. This
week's error by Avast caused Avast to identify many legitimate
programs as being Trojan-infected. It should have been pretty easy
to tell that this was a error in Avast's update, still many people
panicked and placed good programs "in the vault" or deleted the
program(s) completely. So, next time something like this happens,
don't panic - think first. Reporting false positives quickly ensures
that the antivirus program will be fixed quickly.
2. If you've had a problem with a false positive, always manually
update your antivirus in between automatic updates. There's a good
chance a fix will be issued quickly and if it is, manually checking
for updates every so often will ensure you get the corrected update
right away. If you wait for automatic updates you may go an entire
day using the uncorrected virus definition file.
3. Use your head. Don't panic
when the virus warning goes off. First think about what is being
detected and where it came from. There is absolutely zero chance of
Smileycons or Spyware Doctor being Trojans. If you're on a site
you've never been on before and you start downloading something from
that site and get a warning...heed it. It's probably a valid
warning. You can't trust software to protect you 100% of the time.
You need to use your common sense and good security software
together - in tandem - to be safe on the Internet.
Avast responded quickly to this latest false positive - the
corrected file was released just hours after the false positives
were discovered. Avast continues to impress us with its great
protection and small number of false positives. Be sure to manually
check for updates if your using Avast to make sure you have the very
latest definition files and program version. To do this, right-click
on the Avast icon in your system tray and click "Updating" - choose
iAVS update. After completing this step, choose "Program Updates".
After you update the program you'll need to reboot.
