If you have been infected with Antivirus Sentry you may have tried to remove it using add/remove programs. You will have found that Antivirus Sentry reinstalls itself on system reboot/log in. So how do you remove Antivirus Sentry? The correct kind of program to remove the Antivirus Sentry infection is antispyware. Antivirus programs will do nothing to programs like Antivirus Sentry. Look for an antispyware program that has awards. Also, it is my opinion you should not pay more than $40 for an antispyware program. There are several good programs out there for $40 or less. Spending more on an antispyware program does not necessarily mean that you get a better product. Once you have the antispyware program on your computer keep it updated and you will not have to worry about further infection from rogue programs like Antivirus Sentry.
