Security company McAfee has revealed that the most common security threats online come from USB worms and password-stealing Trojans.
USB worms are spread via USB drives and can infect a computer as soon as the USB is inserted into the machine. It can also send copies of itself to other computers on a network.
As well as infections originating from portable storage devices, the other most widespread security issues come from password-stealing Trojans.
The threats were identified in the newly-released ‘McAfee Threats Report: First Quarter 2010’.
Major news events used by cybercriminals
The report also found that those behind major online security threats are using major news events to poison internet searches. Haiti and Chile earthquake disasters, the Toyota recall and the Apple iPad have all been used by cybercriminals to manipulate search engines and send traffic to malicious websites.
Protect yourself against online threats
Trojans, worms and other online threats may be avoided by following some online safety tips.
As a rule, everyone should be wary of opening unexpected emails and should not run attached files, programmes or visit websites contained within untrustworthy emails.
Such attacks will often use language to trick users into running the malicious code, so question it even if it seems like it could be genuine.
All computers should have anti-virus and anti-spyware software installed and kept regularly up-to-date, as well as a firewall.
