I didn’t ask if you could burn CDs-DVDs, but I’ll assume “yes”. One thing I have started doing is collecting the “bootable anti-virus CDs” from various vendors. Most of them can be downloaded in an ISO format, meaning “I can get my CD burner to burn that ISO, and it will create the Bootable Segment itself.”
I am not advocating or recommending any one vendor here, by the way. “Your actual mileage may vary” should be the common excuse, because your equipment, any virus (if there is one) and the current AV-version all have factors in success or failure.
And “failure” may be merely “did not detect”, which may not mean “no virus” but ONLY means “this product couldn’t detect it”. So, I tend to use more than one.
AVG has one for free download.
Panda has one.
Kaspersky has one but it seems like it needs an existing Kaspersky installation first.
BLEEPING COMPUTER will have many other suggestions, too. Some of those hijacker viruses are sooo devious and evil. Best of luck, and obviously the best thing would be “no virus at all”.
