Security analysts from Prevx warned computer users, especially enterprise systems, were threatened by the " extreme " development of rootkit software.

More than 725,000 computers were scanned with the malware detection tool Prevx CSI Malware for a period of two months that identified many different forms of malware and spyware, according to the ratio of 1 in 6 PCs. infection. Especially computers in the system of businesses with the highest rate of rootkit infection.

According to Prevx statistics, the number of rootkit infection computers has increased from 15.6% in October to 22% in early December.

The company regularly records an attack on the university website that traces its "poisoned" cache. This website has been deactivated but the malicious code from it is still distributed through the search engine's cache.

Security firm Aladdin not only specifically search engines have distributed malicious code from the website, but said all the top three search engines today are Google, Yahoo and MSN Live have been the case. Pages cached can "live" from weeks to months until the cache is refreshed.

Most malicious websites have a copy version on the search engine's caching server. However, search engine managers have not taken any action to handle this issue.
