How to avoid catching a virus. What should we do? Stay calm. A computer virus isn’t dangerous until the infected email is opened. Delete any mail you think is infected and empty your deleted items folder. Enable a firewall (защитная система). It’s an application that prevents computer viruses from infecting your computer. Update your operating system regularly. Use spam protection. Many computer viruses get into your computer as e-mail attachments. Mark e-mails that look like spam as spam so that you won’t have to get them in your main inbox and accidentally open them. For further protection, use anti-spam software. Avoid installing suspicious software. Some computer software or programs are hotspots for computer viruses, or they contain viruses themselves. If you are not sure about the publisher of the program, then don’t install it.
What should not we do? Don’t open any attachment you are not sure about, even if you have a virus scanner. Don’t forward any attachment to a friend without being sure it is safe.
