No one can actually give you 100% protection for your computer. But the least that you can do is get a firewall which can help you and protect your very important data. Regular updates on your PC can also help in maintaining. The antivirus software’s too having some subscription formalities which one would have to fulfill.

It’s the best that you take enough protection at first, even before your PC encounters any virus problem. 

There are a few basic steps that one can follow to keep away from the Virus attack:

• Using the Internet Firewall can be of much help.
• In case you subscribe to any of the main programs, you can get some automatic updates.
• Do not open any email attachments which you receive from unknown senders.
• Even though you receive a mail from someone you know make sure you know what the attachment is. Sometimes the person sending you the mail too may be unaware of the virus that he might be spreading.
