• VMyths.com - Is it a hoax? They'll know.

NOTE: If you have already deleted the Jdbgmgr.exe file, some Java applets may not run correctly. This is not a critical system file. The file version may vary with your operating system and version of Internet Explorer. If you want to restore the file, read the instructions in the How to restore the Jdbgmgr.exefile section at the end of this document.

Recommendations

Unfortunately, it's no longer a matter of "if" someone will send you a virus, but "when". These recommendations will limit the likelihood of getting infected by a computer worm or virus.

1. Get Antiviral software.
   We recommend two products. Norton Anti virus and AVG Anti virus, a free anti virus tool for US users.
   1. We primarily recommend Norton Anti virus
      No reason other than we like it's look and interface a little better and Symantec is a trusted company that we don't expect to go anywhere anytime soon (that's not always the case with free versions). NAV has an automatic update feature and if you have ever had anything wiped out by a virus, you realize it's worth your time to buy some software to prevent it. Purchase online or see their download section for a free Trial.
      Web site: http://www.symantec.com
      
      Note: When purchasing their anti virus product they also give you options to "upgrade" to their System Works or other Security Products. There is no need to do this. Save your money.
      
   2. Free anti virus Software
      Speaking of saving money and despite my comments above about free anti virus software, we have found this FREE Anti virus product from GriSoft to be just as good as any of the paid programs.
      Download it here: http://www.grisoft.com
       
2. Patch your System/Software
   Most viruses and worms on the loose today are taking advantage of well publicized"holes" in your email or operating system software. Keep your system "patched" and you'll be immune to many of the most popular viruses.
   
   1. Start here: http://windowsupdate.microsoft.com
   2. From that screen click on product updates. Download all critical and security updates. Also download any in the recommended section that look like they may apply to you. This should help your system stability (fewer crashes and lock-ups) as well as security.
      
3. Be Afraid! Be Very Afraid!
   1. Don't open attachments!
      The vast majority of viruses are executed by opening an attachment. This applies to friends as well as strangers. Unless you know this person has sent you the attachment sitting in your inbox, don't open it. A "no attachment" policy is a good recommendation for any business. Very often infected people send you viruses with attractive subjects like "what do you think of this?" and have no idea their computer is sending out email on their behalf.
   2. Scan everything:
      If you know what the attachment is, and are expecting it, then before you open it, save it to your hard drive and scan it, just to be sure the sender does not have a virus that is infecting other documents.
