Yesterday, 26 August 2019, I downloaded what purported to be a free McAfee program that offered protection against browser hijacking. I have not been able to find it with the other McAfee program on my Chrome extensions page (WebAdvisor, etc). It said that it would flag up any attempt to hijack my browser, and explained what hijacking was and its symptoms, such as slow-running browsers using up vast amounts of memory. It also said that a message would appear, something like 'Do you want your browser to be hijacked?', and warning against dubious sites.
My Chrome browser has been slow, using up large quantities of memory, hence my interest in this program, and it still does run slowly. Can anyone advise whether this program is genuine, or whether I've managed to download a fake, some malware disguised as a legitimate program. I can't find this program on McAfee's free download pages. Unfortunately, I CCleaned my PC yesterday evening, so I can't look back at what sites I visited.
Madhan called me this afternoon and we discussed the question that I raised. It seems fairly certain that there is no problem and no need to take action other than carrying out routine virus checks and checks with McAfee download tools. My thanks to the team for dealing with this.
