drealmer7: Again, I recommend CCleaner! There was actually a time where that was all I used, without even MSE, and it kept me virus free with no anti-virus software for many years.
CCleaner will not remove any rogues, ransomwares, backdoors, keyloggers, rootkits and bootkits. It's a "cleaning" tool that removes temporary files, purges the browsers' cache, history, sessions and cookies, and fixes errors in the registry. It's an extremely helpful application
(which I personally use), but it's not enough to ensure a proper protection. It will never replace a good antivirus / antimalware.
I highly suggest you to download and install
<span class="bold">MalwareBytes</span>, it's one of the best antimalwares, it's free and it will not interfere with your current antivirus. Other useful applications are
<span class="bold">AdwCleaner</span>,
<span class="bold">Kaspersky TDSSKiller</span> and
<span class="bold">Dr.Web CureIt</span>. For power users, there are also
<span class="bold">MBRCheck</span> and
<span class="bold">Combofix</span>, but you need to be very careful when you use them! For safe browsing,
<span class="bold">AdBlock Plus</span> and
<span class="bold">NoScript</span> are very helpful, as well as checking URLs with
<span class="bold">VirusTotal</span> before visiting obscure websites. One of the best antiviruses is the common sense!
I'm not recommending MSE, it's one of the weakest antiviruses.
<span class="bold">Avira Free Antivirus</span> is a better choice, as long as you uncheck all their offers
(Avira SafeSearch, Avira SearchFree, etc). If you're willing to pay, I strongly recommend
<span class="bold">ESET Nod32 Antivirus</span>, which is lightweight, reliable and fast, and offered in 32 and 64 bit versions. It can be installed on older computers without slowing them down.
