Users duped by variants of old viruses have not updated their anti-virus software, Wraight concluded. Nor have they heeded media and experts warnings about opening attachements from
In addition to viruses, Internet hoaxes continue to sow confusion among users. The multi-lingual JDBGMGR hoax, which claimed to be an extremely dangerous virus

“Simple to implement anti-hoax policies can help limit this confusion and will prevent hoaxes from needlessly clogging up email
servers and wasting valuable bandwidth,” Wraight said.
The top 10 viruses for August, as reported by Sophos are:
1. W32/Klez-H(Klez variant)17.0% 2. W32/Yaha-E(Yaha variant)6.4% 2. JS/NoClose(NoClose Trojan)6.4% (re-entry) 4. W32/Badtrans-B(Badtrans variant) 5.3% 5. W32/ElKern-C (ElKern variant)5.1% 6.
