Business computer users recently experienced an increase in web-based malware attacks, according to research from Cisco. The company said there was a 103 percent increase in the first quarter of 2011 compared to 2010, with a major factor being drive-by downloads used to install viruses on unsuspecting victims. Antivirus software should be used to help prevent these malware assaults.
Techworld said drive-by downloads are dangerous due to the fact that they are so stealthy. These malware schemes enable unauthorized users to get control of software and code on victims' systems, make it harder to identify and prevent.
"Drive-by downloads can strike without warning, and only some of them are avoidable. An increasing number are not avoidable," said Andrew Brandt, director of threat research for Solera Networks' Research Lab. He said advertising networks use this for viruses because it's easier to get their exploits out to many people.
With the rise of these types of attacks, computer users should take extreme precaution while opening emails and links. Investing in a good internet security program is also an effective way to help keep a computer safe.
