Security experts have warned the emergence of a new malicious variant of the Download.Ject worm, which Microsoft has released and patched in security bulletins MS04-025.
& nbsp;
In addition to stealing information and recording keyboard tasks, the new variant of Download.Ject also performs a pop-up display of links to pornographic websites. This worm exploits one of the vulnerabilities in Windows to attack a computer, and is currently spreading fairly quickly on the Internet.
& nbsp;
Unlike the previous version of Download.Ject, designed to steal sensitive information such as credit card numbers, ATM codes, etc., the new version generates pop-up ads directly linking. Go to porn websites by changing the homepage and the IE search bar on the infected computer. IE's home was changed to a website called TargetSearch.
& nbsp;
New worms spread among AOL and ICQ instant messages from specified or unknown sources. Messages of this type usually contain a reference and a link to the individual site. When users click on these links, the system will automatically forward to a website and the computer immediately infected with the virus.
& nbsp;
Security companies are rapidly updating virus signatures for their antivirus products. According to the announcement, the system installed Windows XP SP2 or patch in the digital security message MS04-025 will not be affected by the virus.
