This PC CAME with Avira antivirus software already loaded in. It was ineffective. My dentist told me to use Skybot as well as Avira; so now I have 2. Is that OK? Do the systems counteract each other? Also, after downloading Skybot, my PC CRASHED and NOTHING was responding. The machine could not even log-off for about 7 hours. Should I delete Avira or leave it?No it is not okay and please stop starting new threads every time you logon here. Haven't you noticed the mods keep closing them?
You need to either:
1) follow directions or
2) stop posting or
3) reformat and start from scratch (probably your best bet at this POINT)4) stop taking advice on PC maintenance from your dentist. 5)LOL...

It is better to use one antivirus than two. It may slow your pc performance.ADVICE cmatt give out


Running two anti-virus problems can cause several problems. The main concern is that the programs will "*censored* heads" and this can cause them to not PROPERLY scan, detect, and remove infections. Also, running the two together can hog up a lot of resources. Having more than one program on your computer is fine, but you should only be running one of them at a time.
