New malicious worm spreads via e-mail

A new malicious worm that can destroy files on a PC is circulating via e-mail, the Symantec Antivirus Research Centre (SARC) has warned today.

The Worm.ExploreZip was first discovered on June 6 and has been reported in countries around the world, SARC announced today in a virus alert.

The worm propagates itelf via MAPI capable e-mail programs, sending itself as an attachment with the file name "zipped_files.exe", according to SARC. The body of the e-mail contains the following text: "I received your email and I shall send you a reply ASAP. Till then, take a look at the attached zipped docs."

"The worm then proceeds to copy itself to the c:\windows\system directory with the filename "Explore.exe" and then modifies the WIN.INI file, the program is executed each time Windows is started. The worm then utilises your e-mail client to harvest e-mail addresses in order to propagate itself. One may notice their e-mail client starts when this occurs."

When the worm is executed it also searches the drives of your computer system and destroys file by making them 0 bytes long, SARC said.

The centre has created a detection and repair patch which can be found at ftp://ftp.symantec.com/public/english_us_canada/antivirus_definitions/.

I need power and lots of it. As a Front End Web developer anything less just won’t cut it which is why the MSI GT75 is an outstanding laptop for me. It’s a sleek and futuristic looking, high quality, beast that has a touch of sci-fi flare about it.

MSI GS65 Stealth Thin

If you can afford the price tag, it is well worth the money. It out performs any other laptop I have tried for gaming, and the transportable design and incredible display also make it ideal for work.
