You are responsible!
The other part of virus protection is prevention. And no system administrator or virus scanner can do that for you. You are the one and only person responsible for exercising caution to prevent this from happening. Here are the top rules of virus prevention. We suggest you print them out, staple them to your forehead, memorize them – anything it takes:
DON’T OPEN ATTACHMENTS FROM UNKNOWN SOURCES! We can’t emphasize this enough.
If you get an e-mail with an attachment from a person you don’t know – DO NOT OPEN IT – DELETE IT!
If you get an e-mail with an attachment from a person you know but you didn’t ask for it and didn’t expect it – DO NOT OPEN IT – DELETE IT!
If it really was legit, the person will follow up with you or send it again and no harm is done. If it was malicious and you deleted it – you’re safe. Virii can only spread if they are activated. As long as the e-mail is not opened and the attachment is not activated, you’re safe.
Virus programmers disguise their malicious software to make it look harmless. Therefore do not assume that an e-mail that is marked “Happy Mother’s Day” or “Funny Joke” or “Great Opportunity” or “Free ” is safe. You need to keep your guard up. If it does not look familiar, if it sounds suspicious – DO NOT OPEN IT – DELETE IT!
A virus can come from anybody – your coworker, your mom, your best friend, anybody! Therefore do not assume that any e-mail you receive from anybody you know is safe. Virii spread by replicating themselves unbeknownst to a user by sending themselves to e-mail addresses found in the user’s address book. This means that virii are most likely to get into your inbox from somebody you know! If somebody you know sends you an attachment that you didn’t ask for and didn’t expect – DO NOT OPEN IT – DELETE IT!
Do not open any attachment that has the extension .vbs or .shs! Virii don’t have to be files ending in .exe to be executed. VBS means Visual Basic Script is another programming language, one of many, that virii are written in. Virii can actually be hidden in many types of files. Often infected files are disguised to look like a text file or a video clip to trick you into thinking they are safe and opening them. Be suspicious of every single attachment you get. If you’re not sure – DO NOT OPEN IT – DELETE IT!
Please use common sense
It is crucial to be suspicious and exercise caution. The number one rule is: Delete any e-mail with attachments that you cannot say with 110% certainty that they are safe. Nobody is safe from virii, but you can help fighting them by using common sense. Remember, a deleted legit e-mail takes only a few seconds to resend. But an opened malicious e-mail can cause hours of downtime, lost productivity, unrecoverable data, and cost a company tens of thousands of dollars as a result. Be responsible, use common sense, and think before you click. The virus threat is real.
