to install firefox 5.0, message says avast1web rep20110101 will be disabled. What does this mean? Will it disable the avast antivirus installed on my computer?

What more can I tell you? Firefox recommends 5.0 be installed. When I try to do so, I get a message that says some addons are not compatible. specifically avast web rep 20110101. I have no idea what avast web rep 20110101 is and am concerned that it refers to the avast antivirus protection installed on my computer. I need to know if that is what the message means & that if I install 5.0, I will disable the antivirus protection.

No, your anti-virus protection won't be disabled - just the Avast Web Reputation extension for Firefox, which duplicates features that are already built into Firefox.

Check with Avast to see when they are going to have an updated version available for Firefox 5.

Does this mean that Avast will continue to scan for viruses and protect my computer from harmful or malicious internet diseases?
