What type of anti-virus should I use if I wanted to regain back some megabytes/ram/storage

Any ideas? I have "CleanUp!" but it's not very helpful

[Aura]

Cleanup! isn't an Anti-Virus ?
ESET Nod32 is a good leight-weight Anti-Virus in my opinion, but you have to buy it.

To delete useless junk you can use CCleaner

CCleaner is a freeware system optimization, privacy and cleaning tool. CCleaner is the number one tool for cleaning your Windows PC. It protects your privacy online and makes your computer faster and more secure. Easy to use and a small, fast download. Run CCleaner regularly, suggestively after you are done browsing or using your system for the day as it cleans temporary files such as cookies that may prove harmful.

Running items like CCleaner or Temp File Cleaner (TFC) to clean up temp files is a great start. Then from there you can run items like AdwCleaner and Junkware Removal Tool (JRT) to remove any toolbars, junk programs, etc. Once you've done all that, get a light weight antivirus like Eset or MSE.

The above users gave all great recommendations. OP I suggest on following through with one of the other.

Oh my bad, didn't understood your question that way. In this case then, everything Grim suggested will do a good job and fit your needs.

I love Eset and recommend it to you. New version is really awesome and the thing I love most is It doesn't effect pc speed.

You can use WinDirStat to find out what's taking up the majority of your space.

In my opinion CCleaner is best. But, ESET is ok, too...

Is it a lot more worth it to get a paid version of ccleaner or will free be enough?

No temp file cleaning softwares are worth buying.
