Always act with caution

Common sense will always be one of your most valuable weapons in the fight against viruses: always treat all data entering your computer with caution.

If you receive unsolicited files from an unknown source, through chats or newsgroups for example, don't open them. Reject these messages, no matter how enticing they might seem, they could contain a virus.
Do scan all new e-mail messages received before opening them, even if you know the sender.
Don't download from unsafe or dubious Internet websites and when you do download from the Internet, make sure the site is backed by a respected organization, publisher or antivirus developer.
Do be on the lookout for suspicious activity in your computer (increase in file size, unusual Windows messages, mail from unknown senders, or in foreign languages etc.).

Don't be caught unaware, keep up-to-date on the latest developments by subscribing to security news bulletins .
