Malware: Defenses

Kinds of malware Viruses  Macro Viruses  Memory-resident viruses  File infector viruses  Boot Viruses  Trojan Horses  Hoaxes  Worms

Some avoidance tips Install an anti-virus program and keep it up to date  McAfee or AVG from Be wary of unexpected links and attachments Don't use P2P/BitTorrent Never turn off your anti-virus or your firewall. Check thumb drives, floppies, burned CDs and DVDs Don't accept files from unknown people when using Internet Chat programs such as MSN Messenger, IM, Yahoo Messenger, IRC.

Symptoms of a sick System Frequent crashes and system restarts slow/erratic performance Broken/erratic internet connection An active internet connection in an otherwise idle computer Stuff in your sent folder you didn't send. Missing or corrupt data/files.

What to do? Update your antivirus software. Disconnect from the internet: turn off your modem/router and wireless. (Quarantine every computer) If your antivirus found the virus and cleaned it, you are fine, otherwise:  Boot into safe mode  Do a system virus scan. Repeat until clean.

If you cannot get on the Internet... Your virus may have fiddled with a file called HOSTS Its full name is: C:\WINDOWS\SYSTEM32\DRIVERS\ETC\HOSTS on most systems (XP and VISTA, probably Windows 7 also). Its contents should only be: localhost and (in Vista, Windows 7): ::1 localhost There may be some lines with ipv6xx names on them, they are OK. Edit the file with Notepad

Operating System Security Features KEEP YOUR OS UP TO DATE; set it to check for updates periodically (at least once a week). Install and run antivirus software; keep it up to date (it should update automatically). Keep your Firewall operational. In Vista and Windows 7, (and in the MAC), every time some program tries to change the system in some significant fashion, a window prompt appears. Called UAC in Windows, it can be turned off. DON'T

More System Security Features Be sure to set up all accounts as STANDARD accounts; have a special Administrator account (hopefully called something else) for admin tasks. Windows has something called Data Execution Prevention (DEP). To set:  In XP: use sysdm.cpl, Advanced, performance, click on Settings and choose the level.  In Vista/Windows 7: system, Advanced System Setting, Advanced Tab, Settings, DEP settings.

Viruses on Other devices On the MAC: before OS X there were about viruses.; only a handful for OS X. So, not a real problem; however:  PC viruses can happily live (dormant) in MAC files.  Newer MACs can run Windows, and there, all bets are off. Unix/Linux have seen a handful of Virus, none for monetary gain. It is possible, now, to run Windows in Linux, so, again, the Caveat above applies. Also, PC viruses can exist in any file.

Viruses in Phones/PDAs Attacks against cell phones: Through SMS messages. The possibility existed. Otherwise Five kinds of devices:  Symbian Handful, spread through Bluetooth  RIM (Blackberrys) None known  Iphones, etc. None known, unless the phone is “jailbroken”  Windows Mobile Phones Too new.  Android Some apps have been malicious, but not been able to spread.
