World’s leading search engine Google has just silently rolled out its major algorithm update code named as ‘Hummingbird’ . You might not know it but you are experiencing it already while searching the internet by using Google. Senior VP at Google said that the new algorithm ‘Hummingbird’ affects 90% of all searches, and has been in place for about a month. Hummingbird is the most significant algorithm change after the “Caffeine” back in 2010. Its been fifteen years of Google search. This major update affects on offering up direct answers to questions? So Hummingbird focuses on parsing searches as complex questions.
The Microsoft Windows Operating Systems use the AUTORUN.INF file from removable drives in order to know which actions to perform when a new external storage device (USB drive or CD/DVD) is inserted into the PC. The AUTORUN.INF file is a configuration file that is normally located in the root directory of removable media and contains, among other things, a reference to the icon that will be shown associated to the removable drive or volume, a description of its content and also the possibility to define a program which should be executed automatically when the unit is mounted.
This feature has been widely criticized by the security community becuase it is used by malware in order to spread by infecting as soon as a new drive is inserted in a computer. The malware achieves this by copying a malicious executable in the drive and modifying the AUTORUN.INF file so that Windows opens the malicious file silently as soon as the drive is mounted. The most recent examples of this are the W32/Sality, W32/Virutas and also the W32/Conficker worm which, in addition to spreading via a vulnerability and network shares, also spreads via USB drives.
Panda Cloud Antivirus is the first free cloud-based antivirus thin-client. It consists of a lightweight antivirus agent that is connected in real-time to PandaLabs’ online Collective Intelligence servers to protect faster against the newest malware variants while barely impacting PC performance.
When you open Cloud Antivirus, the main window lets you know whether you’re safe or not with a big red or green icon. Cloud Antivirus offers a Quick Scan and a Custom scan for specific folder, files, and drives, and its exceptionally lightweight. You can opt out of contributing anonymous data to the cloud, but that also opts you out of automatic threat management.
There’s a network connection proxy option should you need it, and a reporting feature that will show you what kind of threats have been detected and removed from your computer. You can filter the report by All, Last 24 hours, Last Week, or Last Month, and there’s a Recycle Bin pane from which you can recover a false positive, if you need it. The Recycle Bin is hidden behind an obnoxious “flipping” screen that rotates when you need to access it.
It takes less than 10MB of RAM when idle, and around 60MB when scanning, which should appeal to resource-conscious Netbook users. Panda Cloud Antivirus is a decent, reasonable security choice.
