Users tend to call every malicious program a virus, but the dangerous programs encountered these days are rarely viruses in the technical sense. More commonly, they are worms or Trojan horses. The general name for malicious software is malware.

- Uninstalling McAfee
- Warning!!! McAfee makes it very difficult to uninstall. McAfee has files scattered all over the hard disk.
- Error: "The specified resource language ID cannot be found in the image file" C:\WINNT\System32\...\avsmcpa.dll
- Solution: delete C:\WINNT\System32\avsmcpa.dll
- Installation & Setup
- Trial Versions
- Danger: If you install an evaluation version (e.g. v98i402e.zip), you will notice the e at the end of the filename. McAfee will not allow you to update the DAT file which includes the latest data required to detect and kill the latest viruses. McAfee hides this in the small print: "You may not, however, update VirusScan evaluation copies ... You will not be able to update your DAT files with the evaluation release." The licensed version has an l (letter L) at the end of the filename (e.g. v98402l.zip).

- "We have found that the reason that McAfee runs slow is that there are versions conflicts. Old software remaining McAfee software remaining on the system interfered with the new version. Uninstalling the old software was no easy task. It required manually deleting files and making registry changes. McAfee knows about this. They are the ones who told me what to delete and the new version automatically uninstalls any old software before installing the new." - Lee Trucks - Posted At: 13:45 GMT 2000-10-25

- Ransomware virus scam
- Symantec whitepaper - "Ransomware: A Growing Menace"
- Beware Ransomware | PCMag.com
- While it is colloquially known as ransomware, the virus is called Reveton. It's designated as a drive-by—catchable by just visiting a compromised site.
Reveton works with the Citadel malware platform, which can install other malware so that even after Reveton is removed, keystroke loggers can capture usernames, passwords, and credit card information.
- The malware often announces itself in a pop-up and (wrongly) informs a computer user that their machine has been commandeered by law enforcement for illegal activity. It will not be unlocked, the message says, until a fine is paid. The announcement looks real, but there may be spelling mistakes.
- Do not pay anything! If you pay, you will be asked to pay even more. (MoneyPack/GreenDot, Ucash/PaySafeCard/SmartVoucher, PayPal, etc.)
These criminals will never unlock your computer, no matter how much you pay. Do not contact the crooks.
- DO NOT switch off your computer normally, just hold down the power button or switch it of at the wall.
- Press F8 key while booting. This should bring up the black screen asking if you want it in safe mode. Select 'safe mode with networking'.
- Try to do a system restore to an earlier point in time. (System restore probably won't fix the problem, but it has worked for some people.)
- Remove the hard drive and plug it into another PC as a USB drive, then use an anti-virus program (Norton) to scan it as an external drive.
- Bootable CD solutions:
- Attempt cleanup using a bootable rescue CD, something that many security vendors supply for free. Of course, you'll have to download and burn the CD on a clean system.
Norton Power Eraser is a good example.
- Bootable USB solutions:
- FixMeStick 2013 boots into its own Linux installation and handles scanning for malware automatically; you don't have to interact until you give it permission to clean up what it found.
- HitmanPro 3.7 is specifically designed to fight ransomware.
- Reformat the boot drive. Reinstall the operating system. Since you always do regular backups, you can simply retrieve your data from your backup.

- MyDoom worm spreading fast,
Worm creates possessed zombie army to attack SCO website
The MyDoom worm can make a zombie of your computer
The MyDoom worm (also known as Novarg or Mimail-R) spreads via email, using a variety of technical-sounding subject lines and attachment names. If the attached file is launched, and the worm activated, the infected computer's hard disk is harvested by the worm for more email addresses to send itself to. The worm opens a backdoor onto infected computers which allows hackers to gain access.
The worm also spreads via the KaZaA file sharing network, and launches a denial of service (DoS) attack from infected computers (known as "zombies") against SCO's website between 1 and 12 February.
"MyDoom is unlike many other mass-mailing worms we have seen in the past, because it does not try to seduce users into opening the attachment by offering sexy pictures of celebrities or private messages," said Graham Cluley, senior technology consultant for Sophos. "MyDoom can pose as a technical-sounding message, claiming that the email body has been put in an attached file. Of course, if you launch that file you are potentially putting your data and computer straight into the hands of hackers."
"When the MyDoom worm forwards itself via email, it can create its attachment in either Windows executable or Zip file format. It is possible the worm's author did this in an attempt to bypass company filters which try and block EXE files from reaching their users from the outside world," continued Cluley.
- Blaster (msblaster.exe)
- Just being online is enough to get this worm. It doesn't require you to make the mistake of opening an e-mail attachment.

- Microsoft Security Bulletin MS03-026 - All Windows users should install this patch immediately.
- Windows Update (http://windowsupdate.microsoft.com/) will install the patch for you, or you can go directly to Microsoft's Web site to install the patch. Be sure to reboot your system after installation is complete.
- Installing the patch is the preferred solution, but if that's not possible, block TCP/UDP ports 4444, 135, 139, and 445 at the firewall to help prevent external exploitation of this vulnerability.

- Viruses are often delivered with e-mail attachments. Even if you know the sender, the attachment may contain a virus. You must keep your virus protection software data files up-to-date and always scan all attachments. An even safer (but extreme) solution is to refuse to open any e-mail attachment.
- E-mail Attachments commonly use these filename extensions to spread viruses:
- *.bat, *.com, *.exe, *.pif, *.scr, *.vbs, *.doc, etc...
