Avast
Czech security software company

Avast Software s.r.o. is a subsidiary of Gen Digital. It is a Czech multinational cybersecurity software company headquartered in Prague, Czech Republic, that researches and develops computer security software, machine learning, and artificial intelligence. Avast had more than 435 million monthly active users and the second largest market share among anti-malware application vendors worldwide as of April 2020. As of 2025, parent company Gen Digital had approximately 4,000 employees worldwide.
Avast was founded by Pavel Baudiš and Eduard Kučera in 1988 as a cooperative, initially known as Alwil Software. It later rebranded to Avast, and in July 2016, acquired competitor AVG Technologies. At the time, AVG was the third-ranked antivirus product. It was dual-listed on the Prague Stock Exchange and on the London Stock Exchange and was a constituent of the FTSE 100 Index until it was acquired by NortonLifeLock in September 2022.
In July 2021, NortonLifeLock, an American cybersecurity company, announced that it was in talks to merge with Avast Software.

Why this record matters
“Avast” is worth following because a concise public description often conceals a longer documentary argument. Here, Avast, Czech and security provides the most credible route into that argument.
The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated Sep 6, 2026. The linked authority identifier is Q2247432. 1 of 2 selected statements include explicit references; 1 carry qualifiers and 0 use preferred rank. The first chronological checks are 2020, 2025, 1988 and 2016.
Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
