This is the latest in a series of monthly charts counting down
the ten most frequently occurring viruses as compiled by Sophos, a
world leader in corporate anti-virus protection.
For July 2001, the chart is as follows, with the most frequently
occurring virus at number one:
"Sircam, the
virus which has hit the headlines by forwarding personal documents
to addresses found on the infected user's computer, has affected
thousands of businesses this month - even the FBI's NIPC division
were hit," said Graham Cluley, senior technology consultant at
Sophos. "The fact that such a high profile virus is continuing to
trick users is particularly worrying - anti-virus software is
available to stop this worm, yet it is still spreading. Users who
do not want to risk their confidential documents being leaked to
all of their contacts should update their software and follow safe
computing guidelines."
1276 new viruses were discovered and protected against by Sophos
Anti-Virus during July 2001.
The total number of viruses Sophos now detects and protects
against is 66170.
