Microsoft has confirmed that hackers have started using Microsoft Excel sheets to attack PCs; the problem has been detected in all the versions of Excel including Office 2007.

 “There is a flaw in Excel sheets that hackers are exploiting. They send people a malicious Excel sheet. Moment the infected Excel sheet is opened on the computer it launches a Trojan which allows the hacker to control your PC. He can then read your mails, send mails from your machine, get data…,” says Shantanu Ghosh, Vice President of Symantec India

It’s said that even some Adobe Reader and Acrobat files are carrying malware these days. They enter your PC by hiding inside PDF files. Your computer can soon be taken over by the hacker.

Although India has not been hit, experts say it might not take long.

To Protect your PC

• Don't let your PC open PDF/ Excel files automatically. Scan such files before opening.
• Update your anti-virus.
• If your computer gets infected carefully detach it from the system and avoid opening Adobe files that are embedded on websites.

Both Microsoft and Adobe are yet to find out a successful solution for this issue.
