AVG Yeah, the good old AVG, been recommended by many security experts as one of the best free anti virus out there and it has been around for quite a long time now (relatively) and with the new release of AVG 7.5 , Grisoft is (not literally) telling the world that AVG ain't going anywhere anytime soon. Things that make AVG cool: # It auto updates it's virus signature # Other than having an On Demand virus capability, AVG also offers virus protection for your emails - you need to know that not all free anti viruses offer both On Demand and Email virus protection, so any free anti virus which does offer this, it can be considered as a very generous gift :-) # It has a very good reputation for being a really reliable free anti virus application If you are interested to know more about AVG, please click on this link: Read More To download the latest version of free AVG, go here: Get Free AVG Avast! Home Edition Avast can be considered AVG's most haunting rival, most security experts will either recommend AVG or Avast or both as the best free anti virus. Personally, i can't tell which one is better in respect of detecting more viruses and protecting your PC better, but Avast can really boast about it's list of features and cool design. Avast is cool because: # Just like AVG, Avast offers both On Demand virus scan and Email protection # Unlike AVG, Avast has P2P (bticomet,kazaa,limewire and etc) and Instant Messaging (IM) protection - this feature gets a lot of extra points from me :-P # Auto Updates # Has Web Shield - a protection system against attacks from websites ( don't be surprise, there are websites made today which has a sole purpose - to make your life miserable) # Protection from network attack - totally cool for people who are connected to a network such in a University's Network As i said, Avast has a long list of features compared to AVG, so if you are keen to know every tiny miny detail about Avast, head here: Read More Then, if you are interested to get your own copy of Avast, click on this link: Get Avast PC Tools Anti Virus This AV is the new kid in the block (again, relatively speaking dude!) but sure got under the spot light really fast. PC Tools AntiVirus is developed by the same company that made the famous Spyware Doctor. Though this cannot be a prove that PC Tools AntiVirus is a good free anti virus, but it has to mean something right (the made-by-the-same-company thing) - just like cars, news models from BMW or Toyota is considered good, cause both of the car manufacturers has made many really good models before (a bit off topic :-) ) Anyway, PC Tools Anti Virus is considered cool by me (that is why i recommend it :-) ) because: # It has Smart Updates function - just another funky name for auto update # It has community support - this feature, though may seem unnecessary, but it is really totally useful when you encounter any problems with the application (hopefully there are no problems in the first place) # Just like the two above, PC Tools Anti Virus has both On Demand scanning capability and Email protection # It has Internet Guard - again, this is just another funky name for protection against treats from websites to learn more about PC Tools Anti Virus, go to this link: Read More to download PC Tools Anti Virus, please click on this link: Get PC Tools Anti Virus Lastly, just as a reminder, no one AV can give you a full protection against any attacks, not even the commercial ones can, so please don't expect much from the free ones. Practice save internet activities and probably you won't have to worry about your PC getting infected by viruses :-)
