Which AV does AOL use? AFAIK it used to be Active Virus Sheild but now it seems to be McAfee Virus Scan... is that right?

There are infected files being shared on the network all the time. LW can't control what's being shared, because you download files from other peoples computers rather than from a server

You need to make sure that you keep your AV program updated. And use it to scan all files that you download, before you open the files!

Check the links below for info about viruses & spam to avoid & the last link has more links to freeware AV & anti malware programs.
