PCVaccine is a Korean anti-malware program that pretends to detect PC threats such as viruses or Trojans, but in reality PCVaccine has no ability to detect or delete any form of hostile software. Along with this distinct gap in its features, PCVaccine can also be considered to be malicious software itself due to its usage of totally-inaccurate error messages that PCVaccine leaves in an attempt to make you spend money on its valueless services. Due to these issues and the fact that PCVaccine may also attempt to redirect your web browser or interfere with your real anti-malware programs, SpywareRemove.com malware experts recommend that you get rid of PCVaccine ASAP, ideally by using a PC security application that can do all the things that PCVaccine claims to be able to do.

A Few Reasons Why PCVaccine isn't the Booster Shot That Your PC Needs

Although PCVaccine markets itself as an independent and reputable anti-malware program, PCVaccine bears a strong resemblance to other fake anti-malware applications from Korea, such as BoanKorea, SweeperLab, DoctorCom, BoanCop, Dr.Boan and CleanBoan. PCVaccine's looks may be that of a PC security product, but SpywareRemove.com malware analysts have found that its real functions are anything but helpful, as noted below:

  • PCVaccine will launch itself without permission and refuse to be turned off; even if PCVaccine appears to be closed, its memory process will remain active.
  • PCVaccine will resist removal by normal methods; it's recommended that you use appropriate anti-malware software to rid yourself of any PCVaccine infection.
  • PCVaccine will create fake alerts, warnings and error messages that present fraudulent problems instead of real ones, and then pretend that these issues can be solved if you spend money on PCVaccine's full version.
  • Your web browser may also be redirected to PCVaccine's website due to an altered Hosts file, changed browser settings and other attacks.
  • Your actual anti-malware programs may refuse to run properly while PCVaccine is active, thus preventing you from easily-removing PCVaccine. However, Safe Mode or another method of deactivating PCVaccine's launch routine will allow you to use appropriate software for PCVaccine's deletion.

Protecting Your PC from PCVaccine's Malevolent Doctoring

SpywareRemove.com malware experts especially recommend that you avoid any contact with PCVaccine's website, since this site may reinfect your PC or introduce other forms of malicious software through script exploits and other web browser-based attacks. Be certain that your homepage settings and other browser-related settings are returned to normal before you attempt to use your browser after PCVaccine has been removed.

If your anti-malware programs have difficulty identifying PCVaccine, be certain to update their threat definition databases so that they have a complete definition of PCVaccine if such is provided by their company. Manual removal of PCVaccine, while possible, isn't recommended in most cases, since it entails alterations to the Windows Registry and other components that may require the re-installation of your operating system if they're damaged.

For non-Windows computers, SpywareRemove.com malware analysts are glad to note that PCVaccine appears to pose little danger.
