Безопасен ли avast.com?

I uninstalled your antivirus avast, your antivir is fine in it's job but it's officialy an annoying nagware which became even more annoying and more aggressive in it's ad popups. Installing avast.. it's like installing adware which will block other adware and be the only active adware on your pc and nag you few times a day with it's offers. You're disappointing avast.

This website is the website for a Czech computer security company called AVAST Software s.r.o. It offers several software programs for download or for purchase; they include a free antivirus, a paid-for version of that antivirus with an extra "SafeZone" feature, which is similar to Bitdefender's SafePay, a security suite which includes a firewall, and a beefed-up version of that security suite, called "Avast Premier", which includes even more features than the security suite. From a technical standpoint, this website is virus-free; in fact, it is the website of a trusted antivirus vendor.

Very good anti-virus software. Malwarebytes and Hitman Pro make a great team with it. It is bundled with Dropbox, but that's not a bad program (Dropbox is actually very useful in my opinion) and you have the option to opt out of installing it. I don't really like how Avast charges tons of money for alternative software. It seems that they push it way too often.

I've been using avast! for a long time, and it's the best AV I've used. It has good virus definitions and additional tools for keeping you safe that most antiviruses (if not all others) don't have, such as SafeZone and Sandbox. I also use Malware Bytes with it, and they both keep my PC safe.
