Why are viruses given the names that they have?

We found some unusual backdoors in the past few weeks. They seem like standard variants of Agobot, Rbot and other bots controlled via IRC. However, they contain files that work like EPO viruses.

Yesterday was hot with two new Bagles let loose. The worms were mailed using spam methods in one of the largest mass mailings this year. I hope that the weekend will mean the outbreak will calm down.

The third Bagle we saw yesterday was almost identical to the first two, except for a mistake…

We detected a new variant of Zafi today, Zafi.c. The first two Zafi’s spread widely, so we plan to keep a close eye on how things go.

It’s now the end of October and we haven’t seen any serious email worm outbreaks for months.

When I sit down to think of…

Today’s threats spread further and faster than ever before. This makes updating your antivirus databases regularly essential.

The nature of threats encounted by PC users has changed significantly over the years. Today’s threats are more complex than ever before. So is it still worth using a traditional antivirus solution?

Email worms sent the virusology trend in early spring: Bagle, Mydoom and Netsky all spread as attachments to infected emails, and all used social engineering techniques in order to propagate.
