Tips & Warnings
Practice safe computing and safe browsing. Don’t open attachments from unknown persons. Back up your files regularly. Use Firefox browser instead of Microsoft Explorer. Firefox has a reputation for safety and the developers update it regularly.
Keep all programs running on your computer updated. Not every program will update automatically so you may need to update them manually. Check the manufacturer’s website for instructions and updates. Failure to update your programs is the same as keeping the back door to your home open and inviting unscrupulous people in.
Stay away from file sharing sites like Kazaa and LimeWire. They are hotbeds for viruses, spyware and keyloggers.
