HOW YOU CAN GET INFECTED
Booting the computer from an infected hard disk, cd-rom or diskette.
Executing attached infected files (.exe, .com, .vbs, .dll, .sh, .bat , .scr, .pif and more) you may find inside emails.
Executing infected files (.exe, .com, .doc, .bat, .hlp, .htm, .ini,
.js, .php, .pif, .reg, .ppt, .scr, .sh, .shs, .sys, .vbs, .wbt, .xls
and more)
Previewing emails usually sent by an unknown person, because they
possibly contain destructive code in the form of .html, that is
automatically executed upon the email preview.
Browsing infected webpages (usually .htm and .html ).
Just by using the internet. To be more specific, almost every operating
system, especially Microsoft Windows, have "security holes" which are
exploited by a new type of viruses in order to infect the computer,
without asking at ANY point the permission of the user to install any
type of software.
HOW TO PROTECT YOURSELF
Make a backup of your critical files regularly, after having scanned them with an antivirus program.
Update your antivirus program as often as possible.
Scan every file you download from the Internet.
If you use irc chat, make sure you have disabled the auto-accept-dcc-files option.
Try to have a real-time antivirus monitor while your computer is operating.
Don't visit every website you are invited to by an unknown person. It may contain a non-visible destructive applet.
Disable the execution of java or active-x scr i pts within your browser.
Unhide the
hide-file-extension-of-known-filetypes option within your hard disk
explorer. If someone sends you a file called pic.jpg.vbs, you may think
it's a .jpg file and execute it!
Always have a boot disk for repairing your computer in case you get infected. Most antivirus programs offer this disk.
Try to use two different antivirus programs, using only one
real-time monitor. It would be best if one of the 2 programs is in the
top-10 antivirus programs' list you will find in the results of our
LATEST Comparative test of antivirus programs. Security is not a matter
of money, it's a matter of life-and-death for your computer!
Use a firewall program (we recommend Sygate Personal Firewall
-it has been discontinued but you can find its latest version at
"www.virus.gr/sygate.zip"- or Outpost Firewall Free or Comodo Personal
Firewall or Kerio Personal Firewall, which are absolutely FREE and
manage to protect efficiently any personal computer - NOT to be used in
corporate network).
Use an anti-spyware program (you can find a list of good and
freeware ones in the "FREE antivirus software" section of the website).
Try to update the operating system of your computer often (especially
Microsoft Windows), so that all known security holes are fixed. We
should mention that certain Microsoft operating systems do NOT allow
the user to install updates if they have not been purchased!
WHAT YOU SHOULD DO IF YOU GET INFECTED
Avoid installing an
antivirus program if you are sure you have been infected by a computer
virus. As a first choise, we advise you to use the "Free Antivirus Tools Collection" available in our website and remove the virus.
If your antivirus program detects the virus but cannot repair it, do
NOT delete the file! Try using another antivirus program, maybe it will
be able to repair the infected file. None of the antivirus programs is
perfect, still, the difference among them may be huge!
Do NOT format your hard disk! Formatting is NEVER a 100% guaranteed
solution in order to face a computer virus. Have patience, faith in the
antivirus program you have chosen and ... a bit of good luck!
