The infamous Klez worm has retained the top spot in security firm Sophos's most frequently occurring viruses table for the fifteenth month in a row, while 475 new viruses were discovered in April.
Two old favorites also reared their heads again--Lovegate-E and Funlove--spreading concern that individuals and companies are not keeping their antivirus software and firewalls up-to-date.
"It's no good installing the software if it's not maintained," says a Sophos spokesperson.
A new virus called Datemake Dialler also made its way into the top ten. The malware, known as a dialer, is programmed to dial a premium-rate telephone line, typically with the intent of gaining access to adult material.
"Businesses should apply strict computing guidelines to avoid getting stung by a huge telephone bill and embarrassed by these seedy programs," says Graham Cluley, senior technology consultant at Sophos.
