Most people have some data that they would rather not share with others – passwords, personal information, classified documents from work, financial records, self-written poems, the list continues.
Perhaps you have saved some of this information on your computer where it is conveniently at your reach, but when the time comes to remove the data from your hard disk, things get a bit more complicated and maintaining your privacy is not as simple as it may have seemed at first.
Your first thought may be that when you ‘delete’ the file, the data is gone. Not quite, when you delete a file, the operating system does not really remove the file from the disk; it only removes the reference of the file from the file system table. The file remains on the disk until another file is created over it, and even after that, it might be possible to recover data by studying the magnetic fields on the disk platter surface.
Before the file is overwritten, anyone can easily retrieve it with a disk maintenance or an undelete utility.
There are several problems in secure file removal, mostly caused by the use of write cache, construction of the hard disk and the use of data encoding. These problems have been taken into consideration when Eraser was designed, and because of this intuitive design and a simple user interface, you can safely and easily erase private data from your hard drive.
Eraser is an advanced security tool for Windows which allows you to completely remove sensitive data from your hard drive by overwriting it several times with carefully selected patterns. Eraser is currently supported under Windows XP (with Service Pack 3), Windows Server 2003 (with Service Pack 2), Windows Vista, Windows Server 2008, Windows 7 and Windows Server 2008 R2.
Google has just announced something pretty interesting, that it is using its own data to detect viruses and will as of today be using Google Search results pages to warn users if their computers are infected with a specific form of malware. Users infected with the virus, which is apparently rerouting traffic to Google and other sites through a proxy, will see the below warning.
“Recently, we found some unusual search traffic while performing routine maintenance on one of our data centers. After collaborating with security engineers at several companies that were sending this modified traffic, we determined that the computers exhibiting this behavior were infected with a particular strain of malicious software, or “malware.” As a result of this discovery, today some people will see a prominent notification at the top of their Google web search results.”
Google’s Matt Cutts offers more details about the virus on his Twitter account, apparently it only affects Windows computers and hijacks Google results. “That’s how we learned about it,” Cutts says about the “results hacking” thing, without offering many more details. Google is recommending you follow the advice in its Help Center if you do receive the notification.
This is the first time major search engine turns its results pages into what is ostensibly a malware alarm. Of course this is in the company’s best interests; if proxies are intercepting communications they could also potentially access Google accounts, thus creating more headaches for Google.
