Re: How Many Anti-Virus Packages Does It Take?

Like many people I used Norton for years until it slowed my computer to a crawl. I then switched to Kaspersky.

Interestingly Norton used to pop up with notifications of viruses that it had found, especially when renewal was due, but Kaspersky found more than 200 infected files that Norton had been ignoring for years.

Re: How Many Anti-Virus Packages Does It Take?

At the mo, I just use Windows Defender. I dallied with Malwarebytes, which said that it had founder several trackers, but it seemed to cook my cookies. So don't use it at the mo...…….FWIW..

Re: How Many Anti-Virus Packages Does It Take?

I am just in the middle of updating my daughter's PC as she needs some real CPU muscle for her animation degree course (installed a new motherboard with an AMD Ryzen 7 2700 X - it has 8 cores, each of which can run two threads, so that's 16 threads!).

I did initially install Bitdefender but that interfered with Firefox and I am now trying Sophos Home, which seems OK. I am also trying the free version of Zone Alarm to replace the Microsoft Windows firewall. All of these come highly recommended by reviewers at the moment.

I also use Malwarebytes simply as an extra though only run it manually from time to time.

I used to get Kaspersky free with Barclays Banking, but they dropped them after all the alleged hacking by Russia.

I now use Sophos, which was what we used at work.

Re: How Many Anti-Virus Packages Does It Take?

I used Sophos for a while and quite liked it. However, the (paid) version that I had did not intercept incoming infected email attachments, (these are supposed to be dealt with on the main server before they reach client machines). The result was that infected files were downloaded and remained undetected on the email client until they were executed. Only then did Sophos act to block them.

I never use A/V. It's a virus in its own right!

Re: How Many Anti-Virus Packages Does It Take?

I used to subscribe to a security newsgroup some years ago. The consensus there was that if a virus is detected on your system, your system is essentially toast and it's a flatten and rebuild job!

The argument went like - the virus is in your system and a sophisticated virus will alter and hide itself to avoid detection.

I also ask myself 'In whose interest is it that computer viruses exist and new ones pop up now and again? Who's making a lot of money out of computer viruses?' The conclusion I always come to is that it's the anti-virus companies, and it wouldn't surprise me if they are also the source of many viruses.

That very problem was one reason I had a very old XP laptop that I used for e-mail and would open “suspect” files on that. With only a 20GB hard drive, which I could easily swap for a clean one, I effectively had a “dirty” system for the internet, completely separate from the work place systems.

File content was only ever transferred by ascii text files, once the system had been fully Sophos swept. In all the time we used that system only two files were flagged as “suspect”.

Well, here's my train of thought...

1) A/V always lags the viruses. They are not a guarantee of immunity. The worst of recent viruses have caused havoc before AV caught up - e.g. the Wannacry attack that brought down a lot of the NHS computers.

2) If you're writing a virus, there are tools (and web-sites) that will help you work around all the common AV packages out there. In a word - if you're determined then AV won't stop you.

3) They hook themselves into all sorts of places within your OS. They can cause performance issues, apps to fail, annoying pop-up to appear etc.

4) AV programs themselves can be targeted by virus writers; and because they hook into the OS as privileged programs they present a nasty backdoor mechanism for viruses to exploit.

5) On occasion they will flag harmless programs as containing viruses.

6) Most viruses don't get onto people's computers via complicated means - they are installed by users failing to apply common sense precautions. I'm talking about things like running EXE or similar files from e-mail attachments, downloading software from dubious sites - that sort of thing. A good sense of scepticism is better than AV in my view.

7) Many AV companies are Russian

If you run your PC behind a router with known PCs and users on its local network then I think the risks of infection are very low so long as you exercise basic common-sense caution.

If you connect to public, open networks (coffee shops, airports) then a good inbound firewall is the best protection you can have. This will stop potential hackers/infected computers getting access to resources on your machine via open network ports.

This is an interesting article:

Re: How Many Anti-Virus Packages Does It Take?

Thanks for that info Paul. Do routers have firewalls etc? What about your provider, I use PlusNet. Do they have any system to reduce the risk?

Couple of years ago I did get one of those Ransom notes, but I reckon it was a scam, as I got out of it just by switching off the computer. It came with a dubious site were I was downloading "Free" software. After that I now am prepared to pay a reasonable price for software...

I can see that the A/V companies really stoke the virus threat, but if I did get one...…………

A recent problem with CCleaner was that some one had managed to attach a virus or whatever to the download site. Alas I got that one on the wife's computer. She has yet to forgive me...………..

Routers do have firewalls but you still need one installed on your PC because the PC firewall works differently, managing accessibility to and from programs on your PC. In turn, thos programs will need to work with the router firewall if they send and receive data outside the local network.

Viruses and other malware can get through firewalls by being packaged as attachments or within other programs. This is why you need real-time defence and that is what ant-virus software does.

Above all, be sensible with file attachments and don't install and run untrustworthy software.

Finally, keep regular backups in case something goes wrong!
