Generally yes. Any of the large, reputable anti-virus companies will have better paid products than most of the free solutions out there.
You need to download an antivirus program. A good free program is AVG. A good paid program is Kaspersky.
Yes AVG has a free anti-virus program and also a paid for version. Another alternative which I personally use is Avast Home Free. IMO, it is better than AVG, which I have also used. Go to www.download .com and search for Free anti-virus programs.
AVG is a reputable free anti-virus program. It has paid options, but basic protection is no cost.
There are some free anti virus software available but it is not as good as the paid ones. If the virus is preventing you from being able to use your virus software you will have to go into safe mode and remove the virus manually.
Free virus scan and removal programs are adequate for most computer users and work well to catch common viruses. Paid versions offer more coverage as well as computer support.
The best way is to get an anti-virus program, and run scans with anti-malware programs every now and then. Avast is a good free anti-virus - it uses very little RAM and is powerful enough for an everyday user. Norton 360 is highly rated and considered to be the best paid anti-virus.
Free anti-virus software often provide limited services from within the program, such as a weakened search of spyware as well as the complete denial from a specific action. Paying for the anti-virus software allows these restrictions, meaning you can use anything that is available.
First, you must remember that for the most part free anti virus programs are not mint to be used for long term use, instead, they are generally only supposed to be used temporarily to get a feel for their program. Most of the time, with a free version you will only get part of the virus signatures and some of the features, but not all or it wouldn't be free. I guess however, if you just could not afford an anti virus program say a couple a weeks or so it would be better to have a free version than nothing at all; so here are two free anti virus programs for you to choose from but remember, these aren't full version the chances of you getting something malicious is still pretty good. AVG 9.0 here http://download.cnet.com/AVG-Anti-Virus-Free-Edition/3000-2239_4-10320142.html my personal favorite which I've used many times to remove viruses that even full paid version can not remove is here http://malwarebytes.org
There are a number of free antivirus programs present on the web. Here is a list of some of the best ones: Avast Immunet Plus Comodo Kaspersky Avira MSE AVG
There are two types of anti-virus software you can obtain: Paid for and free. Obviously with paid software it would be a bit more thorough than a free one (ex. McAfee and Norton). However if you are on a budget software like AVG is more than adequate as a anti-virus.
It depends if the program comes from a reliable vendor if they do then NO however free AV programs are not a refined as paid programs so they may produce false positives more often. But a some free anti-virus programs are actually a virus/trojan and they will fake viruses and try to get you to pay to remove them. and steal your credit card number if you want some free good reliable anti-virus programs i would recommend: Avira, Avast, Trendmicro, IObit, AVG, and Malwarebytes
Microsoft Security Essentials and Avast virus protection are two free solutions that are good for home computer needs. They are often more highly rated than paid antivirus solutions.
