I have a macbook pro. Recently, i've scanned my computer for virus's using sophos anti-virus and it says i've a virus in my/Library/Application Support/Apple/.SafariArchive.tar.gz file. my problem is, I do not know how to retrieve/delete this file. Help?

You needn't bother. It's an error caused by an unrecognized filetype. This triggers errors in many AV programs where there actually is not virus.

The file you went looking for is invisible, and that's why your could not find it. It's invisible for a reason, so you won't mess with it.

You should get rid of Sophos. It isn't needed. There are no known viruses affecting OS X.

Helpful Links Regarding Flashback Trojan and Virus Protection

1. An excellent link to read is Tom Reed's Mac Malware Guide.
2. Also, visit The XLab FAQs and read the FAQ on malware.
3. For general anti-virus protection I only recommend using ClamXav.

Again it says that the file infected is in the safariarchive.tar.gz.

What is the name Sophos uses for the infection?

That file stores an older version of Safari following an update. Most likely, you were infected with Flashback at some point and the infected copy of Safari ended up archived in that file. If that is the case, Sophos will call the malware OSX/Flshplyr-X (where X is some letter). In any case, though, there's no need to worry... whatever's in there can't hurt you, as long as you don't expand that file and try to use the version of Safari it contains, and eventually it will be replaced by a newer version of Safari by another update.
