More than half of computer viruses
last a mere 24 hours.
Panda Security's malware
detection laboratory, PandaLabs, has been analyzing the nearly 37,000
samples of new viruses, worms, Trojans and other security threats that
it receives each day and found that 52 percent of them work for just 24
hours. "After that timeframe,
they become inactive and harmless
as they are replaced by other, new variants that join the list of new
specimens in circulation," according to PandaLabs.
Of course, that still means that about 19,000 Internet threats each day last more than 24 hours.
says the reason so much of the malware becomes inert in such a short
time is to increase the chance that they will go unnoticed and can be
spread through other means to other victims without being identified by
the past year, the number of security threats PandaLabs has received
has increased enormously. The company had recorded 18 million malware
samples in its entire 20-year history, as of last year. As of July 31,
however, that number had leaped to 30 million.
"This is a never-ending race which, unfortunately, the
hackers are still winning. We have to wait until we get hold of the
malware they have created to be able to analyze, classify and combat
it," said Luis Corrons, Technical Director of PandaLabs.
