免費惡意程式清除工具Norton Power Eraser

The NEW Norton Power Eraser takes on difficult to detect crimeware known as "scareware" or "rogueware" that cybercriminals use to trick you into unknowingly downloading threats onto your PC. This growing form of crimeware uses bogus pop-up alerts or security messages that scare you into thinking your PC has been infected and needs to be fixed immediately. It can be so tricky that it automatically downloads onto your PC even if you didn’t actively click on anything! The Norton Power Eraser is specially designed to aggressively target and eliminate this type of crimeware and restore your PC back to health.

諾頓的這個Norton Power Eraser清除工具主要是針對一般防毒軟體所無法偵測、清除的「Crimeware」，也就是一系列具有危害使用者權益、盜取信用卡資料或帳號密碼... 等行為的惡意程式。

透過Norton Power Eraser，可掃除深度嵌入、難以移除的各種惡意程式，但如果真的找到可疑程式的話，建議先仔細檢查一下再進行處理，避免錯傷無辜。

免費防毒軟件 Panda Cloud Antivirus Free Edition 1.1.2

Download Panda Cloud Antivirus, 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. Thanks to Panda Security's Collective Intelligence malware and goodware online database, Panda Cloud Antivirus detects more malware than traditional signature-based solutions which take longer to detect the most recent, and therefore most dangerous, variants. Panda Cloud Antivirus protects you while you browse, play or work and you won't even notice it. It is extremely light as all the work is done online in the cloud. Panda Cloud Antivirus provides you with the fastest protection against the newest viruses thanks to its cloud-scanning from PandaLabs' servers. Panda Cloud Antivirus is truly install and forget. Don't worry about updates, configuration or complicated decisions ever again. With Panda Cloud Antivirus, Panda Security is introducing a new protection model that utilizes a thin-client agent and server architecture which processes and blocks malware more efficiently than locally installed signature-based products. Traditional antivirus products for PCs rely on multiple locally installed technologies which intercept each file at different layers (entry vector, file system and execution) and scan them using various techniques (antivirus, heuristics, intrusion prevention, behavioral analysis, etc.). This process results in heavy usage of local PC memory and CPU resources, negatively impacting performance Panda Cloud Antivirus includes local and remote antivirus, anti-spyware, anti-rootkit, heuristics and goodware cache, while only consuming an average of 22 MB of RAM and 50 percent of the PC performance impact as compared to the industry average.
